I have read a little on these devices over the past few months, and decided that for ham radio use, if they worked as well as people seemed to think, the small size, internal battery etc. Would make it ideal for field antenna work.I really wasn't expecting that much at this price. However, it arrived in a nice looking box with fitted internal compartments for cables, connectors etc.My first quick play with it impressed me. I was suspicious about using a square-wave and using harmonics for the higher ranges, but if you forgive the reduced measurement range, that actually works pretty well. Not as well as my bench VNA, but that cost just a tiny bit more.

The biggest potential problem is the number of sample points. Being fixed at 101 points is rather limiting for wide-band scans.

That said, its not that usual outside of microwave use that wide. I ordered this think it couldn’t do that much or be very accurate for the small price they were charging but I was blown away with how well it really works. I compared it to a Bench VNA and it was so close I couldn’t believe it. For ham radio field use and around the shack it is perfect. It does have one small problem, the case it touching the display and if I squeeze the case any amount at all the menu pops up but that should be a easy fix just take it out the case and file it down some or I may print a new case. Glad I bought it. There are so many versions of the nanoVNA out there, from different sellers & manufacturers, including many on Amazon, with different cosmetic appearances, different build details and different included accessories that it is hard to choose which to buy.

Worse, it is difficult to tell if a given seller is accurately representing what he is actually shipping.The AURSINC nanoVNA is the 'real deal', exactly as described in every detail. I ordered early November 2019, and received it a week later, along with other things from the same Amazon order (I'm cheap and use free shipping!) Mine has firmware compiled October 18th 2019, apparently based on the GitHub version of Oct.

7th, so nice recent firmware for those, like me, who use only the basic functions and will likely never flash new firmware. (I do flash firmware on similar devices, but reluctantly.) It has the 'D2'.

I have only had this device for a short time (. You'll want to google it when you receive it, cause there are no instructions. (Though it's pretty darn intuitive if you've used other vna's.) There is a HUGE user community and a lot of options.

There's NANOVNASHARP software available for PC and Linux, if you want to use your PC to control it. Works fine standalone. Comes with dummy plugs and open plugs, and passthrough cables. You'll probably want to buy adapters to get connected to big coax cables.

It does everything my $700 vna does, and more. This one tool covers HF, VHF, and UHF. The photo is a simple SWR chart for one of my fan antennas. Awesome results about ten minutes out of the box. Would have only taken five if I had watched any of the YouTube tutorials first.

Short story form is that if you have a need to analyze transmissions in the RF Spectrum, I highly recommend this device or one of the many other models created by the same company. For specifics, read on!In my initial research, I was concerned that this product being comparatively cheap as it was and coming from such a small operation, would be an underperformer. Reading a few reviews I ultimately decided to take the plunge. I compared several models, and seeing the cost difference between the several base and combo models, I chose the 6G Combo as it covers all the frequencies included in other models with what I consider to be a small increase in price for all this coverage. I have not been disappointed. This model (6G Combo) has the capability to analyze signals in the 15-2700 MHz as well as 4800-6100 MHz. This is an excellent handheld spectrum analyzer for the money.

I’m using it primarily for the ISM 902 - 928 MHz Band, and adjacent frequencies to observe potential interference. As an out of the box test, I set my radio to transmit on 914 MHz, and found the resolution on the RF Explorer to be very accurate. The tuning is very intuitive, as there are only a few buttons to choose from.

I would highly recommend this analyzer to those who need a very basic, portable and inexpensive device to take out into the field or do light work in the lab.Update: I’ve decided to purchase the Touchstone Pro software for $49.00 after trying the free version. The software is very intuitive, and the paid version allows for a lot of added functionality such as data logging, pdf reports, and extra modes and charts. If you need to show.

In reading the reviews it seems like a lot of negative reviews are coming from folks who don't really understand what they're buying. This isn't a tool for average consumers trying to figure out if their microwave oven is making them sick. It's really much more designed for professionals who know a lot about RF equipment and how to work with it.As a standalone handheld unit it's a bit of a challenge to use. The interface isn't all that great and the display is very low resolution. But one area where it excels handheld-only is in wifi analysis mode. It's basically the popular 'wifi analyzer' app in a handheld version (see photos). Works great for looking at wifi channel congestion.I think the best use for this tool is attached to a laptop and using the various free software provided.

There are two tools - RF Explorer and Touchstone Pro. I waffled for a long time about spending over $500 for a PAR meter, but I am glad I finally did. Yes it's a bit pricey, but if you want to maximize your growth potential and yield, this is a must have in my opinion.

Until now I was merely guessing about the height to place my lights and just going by the manufacturer's recommendations. It is nice to finally know for sure what level of light (PPFD) my plants our getting.This unit is very well made and easy to use. I did not buy the extender wand, but plan to fashion one. Even though I can hold the sensor under the plants easy enough, I see now it will be easier to take readings being able to hold then sensor with an extender of some kind. Especially as the plants grow and get spaced further apart in my grow. I've had this for a while now. Very useful for adjusting your grow room LEDs especially any more,as the quality of some LEDlights have come a long way.in the current age of buyingChinese.Their burplelites,so to speak aren't the only option out there especially since they are basically a joke.

Oops sorry getting off topic.the meter is valuable because with good old made in the USA LEDs you can actually dim them down because they're so tuned to best spectrums you save substantial money in electricity. I know my lights that I bought from Forever Green Gardens are so powerful that they need to dimmed because the plants grow so fast I almost can't lift the light up fast enough. Infrequently, my HF amateur radio is blocked (overwhelmed) by radio frequency interference (RFI) from my neighborhood. A field strength meter is not sufficient because I cannot assure what I am reading is the RFI frequency. My hope is to identify the specific RFI with my RF Explorer, locate the source, and resolve it. So far, I had one incident, but the RF Explorer antenna was insufficient to pickup the RFI signal and then the RFI signal dissappeared before I could use a different antenna. Bottom line: it clearly presents signals in a graphic format for the HF spectrum I need.

I am pleased. The following problems add up to make RF Explorer into 'a chore to use' when you do not have it connected to a computer with analysis software. Problem #1:.Bug: Switch bounce.When manually selecting a frequency via cursor position, the frequency decrease button (left arrow) often jumps by 2 or more cursor points instead of 1.

Seems like a poor design or poor hardware quality regarding the 'switch bounce prevention' circuit/DSP. Problem #2:.Poor Design: Frequency steps.The manually-selectable cursor point on the RTA display has 111 horizontal positions instead of 101. 110 steps (i.e. 110+1) is not a user-friendly count if a user wishes to match up the cursor points with a known frequency interval between cursor steps. The +1 is to account for the start of the range, such as on a 1-dimensional line graph.For example, you cannot inspect from. A fantastic piece of test gear!

I am new to spectrum analyzers, but am learning fast. Don't count on the owner's manual to do you any good, because there isn't one packed with the unit, nor a CD containing the same.

Even though they say one is supposed to be in the box. As with most Rigol equipment, you have to go on line to get one, and then it is hard to read. You do need to be cautious with what and how you hook up to other equipment, to prevent damage to the analyzer.my biggest fear! I am getting more comfortable with it all the time. For the price, this more than fits my needs.My only complaint is the owner's manual and in knowing what features are turned on, and what are not. It's all there, you just have to.

If you need a spectrum analyzer, this one is a very good choice if you don't have an unlimited budget. I contemplated buying a more expensive used one on an on line auction site, but you never know what problems you will get with a used piece of test equipment. This was actually a lot less money than many people were asking for well used equipment. It is easy to carry around, which is handy. Some of the older spectrum analyzers are only portable if you happen to be a weight lifter.

The color display is very easy to read and offloading an image to a memory stick makes it easy to integrate them into written reports, once you get back to the office. No regrets here. It is a good spectrum analyzer, but it does have some hidden caveats that need to be addressed before purchasing. Extended resolution bandwidth, Enhanced measurement, SWR capability are all modules that must be unlocked (ransomware) by purchasing them. I was not satisified with Rigol's way of doing business in this fashion. Contacting their domestic support also was fruitless concerning this issue (no response, at all).

The price is attractive for 1.5Ghz capabilty with a tracking generator. But this is shadowed by the fact that you must 'unlock' all the other features by PURCHASING them. Rigol made a poor business choice with this option.

2. Jack penate everything £5 new zip code.

You might want to look at other analyzers that have these features inheirent to them, before purchasing this unit. 50 years in RF, and this device would have made so many things easier, if it had existed back then:) But it is in my toolkit now, and gets used just about every day. The 110dBm noise floor really is accurate (but you won't see it with a wide IF bandwidth, folks) and the user interface behaves itself well. The latest (beta) Windoze software has a screen dump now - very useful. Oh, but I could have done so much more with this portable Peak-Hold (storage) SA when I was developing those WiFi antennas two decades ago. I use my HP 8569B for making accurate measurements, and this device to tell me where to look. I don't have to lug around a 50lb precision HP instrument any more.

My advice to newbies is buy it - just buy it - and read the manual from font. Wow.just wow.as a nerdy kid I always wanted a spectrum analyzer but was always heartbroken seeing the giant older ones that looked like massive computers with handles and then seeing the price tag. Fast forward to when I purchased this as a birthday gift for myself (with my friends and family wondering what the hell was wrong with me! More on that later!).

This little guy is simply great, I had read about it and heard about its small start and its simplicity and knew I had to get one, I'm big into all sorts of technology and radio frequency communications is a huge interest of mine and I got the 3G model (15-2700 + 240-960Mhz modules) and it came in a very secure but simple package and was straight to the point. The rechargeable battery and USB port for charging and computer connection is a mini USB port which. I have the 3G and use it for ham radio and other non-professional purposes. For me it is perfect. It is sensitive and accurate and for this price that is unusual.

I can remember using spectrum analyzers that were as big as a small refrigerator and this does about the same things for me in a really compact package at a fraction of the cost.I did have occasion to contact the company on an issue that ended up being an Amazon shipping problem and a real person answered and could not have been more helpful.One way to check these types of SAs is to scan the 1400 to 1427 Mhz frequencies since there are no transmissions allowed here since it is used for radio astronomy. They call it (1420 Mhz) the H Line or hydrogen line to us non astrophysicists. 1420 MHZ (21 centimeters) is where the WOW! I just purchased this and we have not actually had the chance to put it into real field use yet, but I have experimented with it and it is easy enough to set up. Be warned, to me the photo makes this case look larger than it is. It is pretty small and one complaint I have with it is that its padding seems to be glued in and if you want to purchase the rubber protector for the instrument, it will NOT fit in the case unless you cut the foam to be wider and a little longer.

It will fit, but it is not easy to modify since the padding is glued into the case. Note: like others have stated, this unit will not charge via the USB port unless the On/Off switch is in the ON position. The manual clearly states. I'm happy with the RF Explorer 6G combo. The case is small but sturdy. I wish the case had room to include the USB cable. Unfortunately, the case is too small.

When connecting the RF Explorer to a computer, the USB cable plugs into the bottom of the RF Explorer with one of the small format USB connections. In this scenario it's not easy to find a good way to hold the RF Explorer straight up (hands free) so the antenna is free and clear. I purchased the RF Explorer Holder with hopes this will allow me to keep the antenna up while I monitor the computer software during testing.

There is a 1-2 second delay executing computer commands from the software to the unit. Normally this is not so much of an issue, but occasionally I had the software hang on me during testing. In these situations a simple. This is for the Hima NanoVNA-F, large display unit. I don't always leave feedback, but I really like this device. As most of these, there's no real documentation included, but there's a lot online.

This was not the cheapest unit available, but I wanted to make sure I got something I wouldn't regret. I believe I made a good choice. This is a pretty solid assembly, and comes with calibration cables, and loads, all packed in a foam insert, plastic storage box. It also comes with a data/charging cable for USB. It has a long life battery, and charging status indicator. It also works well with the Windows plotting software (available free elsewhere). At first it's a little intimidating, but with a little patience and practice, it's well worth it.

I expect to use this a lot more than my expensive antenna analyzer. I compared them, and they're.

Recently bought this and use it to tune ham radio antennas. It’s very easy to use and conveniently sized. I like that I can save all the most popular frequency ranges to test. I like that it continuously sweeps but wish I could stop that and do one sweep at a time to compare. Most of all I like that it’s accurate. I tested this against my RigExpert and it provides the exact same reading on all my antenna but cost a fraction of what the rig expert did.For basic or portable antenna tuning needs this will suit your needs well.

I’m sure it has a ton of other features that I can use too. I had been sitting on the fence to acquire one of these for a long time primarily because it did not cover 1296MHz where I have and will be spending more time on antennas. A few days ago I took another look and noticed V3.4 2.8 and 4” versions released on Alibaba and now here.Yesterday I received the 4” version NanoVNA-H4. It came nicely packaged as shown in the pictures. It had a Jan 1, 2020 build date using the hugen79 branch, one of the 3 main builds I spotted so far for NanoVNA, and the one specifically developed for this new version hardware. Jan 18th a new build of firmware was released.There is a known bug that if you use a center frequency above 1GHz it may lock up.

If this happens you can power cycle to return to normal. Use start and stop rather than. After watching YouTube videos while waiting, I was calibrated and checking SWR on my antennas within 20 minutes! It comes with upgraded RG-216 cables, a very nice case, calibration ends and a stylus on a wrist strap that is very handy to keep from dropping it. I ordered various SMA adapters and a longer cable. I turned off all info.

Except SWR for now to unclutter the screen, This model also has a working battery indicator and a battery that should last all day. It worked instantly with the software for the 2.8 inch NanoVNA on my Windows 10 64bit system. I don't have the best eyesight and can read it fine, so happy I spent my money on this rather than an expensive one like the Rigexpert or MFJ! If you are a Ham, just get it. I look forward to learning more about the other advanced functions.

The accuracy of this tiny handheld device is impressive.I was working on an antenna and used this side by side with my Comet CAA-500 MKII antenna analyzer and found that it's highly accurate and also that my antenna needs work.This is a feature/function packed machine and does a lot more than most people will ever need. As an antenna analyzer, it works great and despite the low price, it will read a much larger frequency range than my much more expensive Comet as it covers all the way out to 900 MHz.There are so many features that I went down the YouTube rabbit hole just watching videos on how to use features that I'll never use, but have the capability of doing now as this miniature device is fully capable of doing things most antenna analyzers don't do.The only thing that I'd like to see that this doesn't have is.

I am fairly new to the HAM world, and wanted something to analyze my antennas, especially the DIY antennas I have been planning on creating out of some metal coat hangers. This product fit my need for a good price, and it was the upgraded version of the NanoVNA. There are some great YouTube tutorials on the product if you would need any help.The product shipped very fast, and came EXTREMELY well packaged. It felt like I was opening my old HyperX Cloud 2's (sorry Beyerdynamic, they beat you here). While I am still new to the NanoVNA and Ham world, this product really allows me to build up proficiency and to analyze whether my antenna's totally out of whack, or if I am screwing up elsewhere.

If you're like me, having a relatively cheap piece of mind really goes a long way. I would recommend this product to any. I'm very impressed with this vector network analyzer.

I'm using the NanoVNA-F to analyze the SWR of my ham radio antennas, which span from 1.8 MHz to 450 MHz. The 4.3' screen is easy to view and large enough that I can select options on the touchscreen with my index finger. Because it's portable (18 hour expected run time on 5 AH rechargeable battery), I can take it up on the roof to fine tune a nine band vertical, or measure SWR in the convenience of the ham shack. Accuracy is outstanding and definitely better than the radio's built-in SWR meter.

While using the VNA in the ham shack, I typically run PC software (NanoVNA Saver) to graph each band's SWR, which I can then save or print. The number of data points can also be increased using NanoVNA Saver. Does NOT work with any smartphone app like the smaller H version does. The android app worked very well with the H.Such a shame, this unit has a much better build quality and the big screen is such an improvement over the H. This is the deal-breaker for me and I am returning it.These are different creators, and different chipsets, so expect different feature sets to be available for the different series.I expect this version to mature and I'm sure there will be a phone app at some point. I'll stick with the H for now.

I am very pleased with the performance of this device. The only way a really expensive VNA can beat this is in resolution. There are only 101 data points on this screen, but that is still enough to tell me what I really need to know.

I compared this against one of those really expensive analyzers and they both gave me the same answer (within the tolerance of the number of data points) at 106Mhz to know this little device going to work just fine. The screen is a bit small and takes multiple stabs with a stylus to get me where I want to go, but when I connect it to a pc with the software it does even more than what the small screen can do and very easy to use.

I may never touch that expensive VNA again. Used this device with a WS1228b LED string lights, microphone module, and Arduino NANO to make a colorful audio spectrum analyzer display for music display. There are a ton of Arduino schematics and sketches online, such as FASTLED, NEOPixel, etc. It is a fun audio project utilizing the MSGEQ7 integrated circuit! I decided to buy this board and IC rather than just purchasing the IC and adding the two additional components, the additional connectors, hookup wires, etc.

The jumper wires and connectors included with this device make it very convenient to quickly reconfigure the device for different inputs (microphone versus audio jack input). The artwork and quality of the circuit card construction are also very high quality. I also like that the IC is mounted in a socket and easily replaceable as needed. I purchased this as a tool to assist in placing wifi APs in larger networks. Little did I realize how much I can do with it and how useful it is. The first job I took it out on I discovered a rogue SSID but couldn't find the AP. Just a quick walk around the office and I found an AP tucked behind a file cabinet.After setting up a new AP I did another scan and could chose the correct channel by using the area less used.

Again I discovered another wireless device that was using the channel I would have normally used. Found a lot of extra traffic and noise as well.

I can't imagine setting up any wifi without this tool. And that was the first day!!I have been impressed by their support and company. These boys are STELLAR!I recommend this unit to anyone who has. This product has a lot of potential but the documentation sucks. For example, documentation on P4 of PDF manual refers to a key feature that's not available on the latest app.

The rest of it leaves a LOT for you to try to figure out. This suppose to make RF easier to understand - why make features and UI obscure?The application notes in the blog on their web site are way too short and don't really get to the punch line. Some youtube videos showing exactly how to configure the app and use it to solve problems would have been great - nothing worth watching there.Too bad. Considering returning this product. Android based free Wifi Analyzer was MUCH MUCH better.
