  • 2020 NEW UPGRADED VERSION:The S-A-A-2/NanoVNA_V2 uses a similar user interface to the NanoVNA, but with a different technical architecture, the S-A-A-2/NanoVNA_V2 does not load the initial calibration data at startup, and does not automatically interpolate the calibration data after the user changes the frequency, and must recalibrate or call back the calibration data after each startup and frequency change. Please read the user manual carefully before use to avoid damaging the device.
  • IMPROVED FREQUENCY RANGE: The improved frequency algorithm can use the odd harmonic extension of si5351 to support the measurement frequency up to 3GHz. The 50K-1500MHz frequency range of the si5351 direct output provides better than 70dB dynamic, The extended 150M-3000MHz band provides better than 60dB of dynamics, and S11 noise floor (calibrated): -50dB (up to 1.5GHz), -40dB (up to 3GHz)
  • COMPACT & POWERFUL: The default firmware main function is used for antenna performance measurement. The TX/RX method can measure the complete S11 and S21 parameters. Can be controlled by PC via VNA-QT software,supported for Linux, Windows (7+), Mac OS planned
  • POWERFUL BATTERY SUPPLY: This VNA V2 is battery powered or USB powered; Built in 1950mAh battery, could work for 6 hours continuously, if need extra working time, it can be connected to power bank or power source.
  • Package include S-A-A-2 host (with battery) x1, Micro USB data cable x1, 30cm SMA male to male SS405 RF cable x2, SMA male calibration kit - OPEN x1,SMA male calibration kit - SHORT x1,SMA male calibration kit - LOAD x1,SMA female to female connector x1

It can display the parameter I prefered but I am not sure it's trurstable or not.The 2 port calibration always failed and I don't know why.It can be used if you don't need precise data.

You don't want this one.

NanoVNA-Save will connect at first and then crash once the calibration process begins and will never connect again.

If you can get by with that display alone then these (in general) makes a decent indicator but I don't trust this one on 2m. 70cm and shorter appear realistic, nice notches where where they should be. But 2m is all over the place. Irony being a broad sweep looks believable so maybe i'm introducing noise and don't know it.

USB sting identifies vendor as DEMO!
-- 04b4:0082 Cypress Semiconductor Corp. CDC-ACM Demo

So at this moment I think I have a new to me demo board who won't play with NanoVNA-Save. Amazon is full of cheap knockoffs and I believe this is one.

Late Edit: I gave it an extra star. USB interface is garbage, wont play with either NanoVNA-Save or NanoVNA-View but screen measure values are repeatable. Fully charge, not half-charged, and plugged in is about the only way to use it.
