desertcart.com: [Upgraded] AURSINC NanoVNA-H Vector Network Analyzer 9KHz -1.5GHz Latest HW V3.7 HF VHF UHF Antenna Analyzer, Measuring S Parameters, SWR, Phase, Delay, Smith Chart : Industrial & Scientific

Review: Excellent budget tool (SD Card 'Fail write' error seems can be solved) - I use it for my hobby to make/tune HF/VHF/UHF antennas, HF baluns, ununs to measure SWR (it's nice to see a graph for entire band), insertion loss, reactance, Smith Chart and there is more parameters I didn't try/don't know about yet. But there are lots of good videos on youtube about how to use nanoVNA. Of course there are better much more expensive options for antenna tuning, but I'm on budget and it's excellent tool for the price. This unit does has some limitations: - microSD Card is a nice feature to save screenshots/data files, but I had problems with that. I returned first device because of 'Fail write' error (I tried different 16GB/32GB/128GB cards with no luck). I reordered nanoVNA again, and got the same error. But it looks like there is a solution I found in nanoVNA groups.io. This device does not support newer SD cards. So I found an older slow 16GB SD card, formatted in FAT32 on Windows, inserted SD card in device powered off, powered on device and it looks like it started to work with SD card. I tried the same card before and it didn't work. Not sure maybe it's because originally I inserted the card with device powered on or it had some format issues, but now it finally started to work. To be on safe side I would power off nanoVNA before inserting/ejecting the card. - Only 100 points of measure, so if I set entire 3.5-30MHz band device has a step about 250kHz that is not enough to tune multiband antenna to exact frequency on each ham band. Also device must be re-calibrated for each new band range that is not very convenient. However a good thing that several bands can be saved as a preset, so it's manageable. - Small TFT screen is okay for me, however it's hard to read data in a sunny day, so not the best option for outside. Also sometimes graph covers text, so text is unreadable. - Questionable reliability. It's packaged well and has nice cables, but it's not built like a tank. It's more for indoor use. If I had unlimited budget for my hobby I would get RigExpert for outside use or considered more expensive nanoVNA model with 400 points of measurement and probably bigger screen. But, for the price this model is a way to go for me. It does work and helps me a lot. Overall excellent value.
Review: Awesome VNA meter. - Should have bought this a long time ago. I recently purchased a cheaper version of this without the case. For a few bucks more. I suggest you buy this one with the case and the ability to take a microSD card. Item came well packaged and it works straight out of the box. There are a numerous tutorials on YouTube on how to calibrate the meter. I suggest you watch them as it is pretty easy to do and take a a few minutes to do. This is just another tool to add to the ham box. It also a very useful tool to test out antenna to show you what band is the antenna is cut for and the SWR you're getting back to the radio. Don't solely rely on this. But it's a great tool to give you a baseline where the antenna "sweet spot" its at. I tested several HT antenna you can clearly see where the band or bands the antenna is at. Great and awesome tool for ham operators. Very well made and happy with the purchase.

## Features

- [UPGRADED NanoVNA-H] New HW Version V3.6. It is upgradeable as new firmware is developed. With MicroSD card port now can have the measurement data or the screenshots saved in the it at anytime. Added battery circuit management, more secure. Redesigned PCB, you can connect to mobile phone with Type C-Type C cable (original PCB needs OTG cable), see a clear HD image on your phone. Added a ABS case, which is protective and dust-proof. Disply: 2.8 inch TFT (320 x240)
- [IMPROVED FREQUENCY ALGORITHM] The improved frequency algorithm can use the odd harmonic extension of si5351 to support the measurement frequency up to 1.5GHz. The 50K-300MHz frequency range of the si5351 direct output provides better than 70dB dynamic, The extended 300M-900MHz band provides better than 60dB of dynamics, and the 900M-1.5GHz band is better than 40dB of dynamics
- [MULTIPLE FUNCTIONS] The default firmware main function is used for antenna performance measurement. The TX/RX method can measure the complete S11 and S21 parameters. If you need to obtain S12 and S22, you need to manually replace the transceiver port wiring. The CH0 output level is increased to 0dBm when using the fundamental wave, resulting in more accurate reflection measurement
- [SUPPORT ANDROID PHONE & PC SOFTSARE CONTROL] Designed a practical and simple control application on PC, you can download touchstone(SNP) files for radio design and simulation software. There is a PC interface that adds functionality and lets you work interactively on a bigger screen. Supports time domain analysis function (TDR). Compatible with most Android mobile phones, convenient for connecting to mobile phones. Support Windows Computer Control
- [STRONG AND SECURE POWER SUPPLY] This VNA is battery powered or USB powered. Built in 650mAh battery, could work for 2 hours continuously. For longer measurement time, kindly connect an external power source. The product interface displays battery usage, providing a clear understanding of the power status

## Questions & Answers

**Q: Regarding,  "I could not find any concise instructions. If you google the device there is a ton of info about it. ..." Can you give some that apply?**
A: I did not either but I did google the NanoVNA which is the same and. Saw several YouTube videos that allowed me to calibrate and use the VNA to measure SWR and actually sweep a frequency range of my choosing along with displaying the graph of my choice

**Q: Does it have a touchscreen?**
A: Yes it does!  To invoke the menu touch the bottom right hand corner of the screen.  It is preferable to use a plastic stylus to touch the screen - I use a cut down 5.5mm diameter knitting needle.  The point needs to very blunt (definitely not a sharp point) and well rounded.  This particular model of the nanoVNA is probably the best on the market currently!

**Q: Can this tool be used instead of an regular  antenna analyzer like a Rig Expert?**
A: Yes.  It can produce an SWR plot like a Rig Expert Antenna Analyzer.

**Q: Can this measure spurious emissions?**
A: No,  this is primarily a passive network analyzer for measuring Q, R, L and C, using active pulses for analysis.
You would need a spectrum analyzer and suitable attenuator for measuring any sort of emissions.

### ⭐⭐⭐⭐⭐ Works great.
*by V***P on November 2, 2025*

I didn’t want to spend hundreds of dollars for an antenna analyzer that I might use a few times in my entire life. This was inexpensive and it works fine. It seems like it would be very complicated and difficult to use, but there are lots of videos on YouTube that show how to use it, and if you just follow the steps, it works fine and is not difficult at all.
