ADVANCED NanoVNA V2 Plus4 — 50kHz to 4.4GHz Vector Network Analyzer (4GHz without using hamonics)
The NanoVNA V2 plus4 is a two port T/R (transmission/reflection) VNA antenna analyzer which can measure the S parameters S11 and S21 of a two port network, or the reflection coefficient (S11) of a one port network.
Support PC Control
- Support PC software control, computer software compatible: Linux, Windows (7 or above), Mac OS. The VNA can be more compatible with PC and antenna measurements, when measuring the frequency.
- It works well with a computer to print out Standing Wave Ratios, Smith Charts and other Antenna related information over various frequency ranges
The NanoVNA V2 has two channels, CH0and CH1, corresponding to ports 1 and 2.
CH0 is the S parameter S11, while CH1 is the S parameter S21.
Each trace can be set to display data from either channel.
To change the channel used by the currently active trace, select
DISPLAY →CHANNEL →CH0 REFLECT or DISPLAY →CHANNEL →CH1 THROUGH.
Configure the measurement frequency range: Select STIMULUS > START and STIMULUS > STOP
Calibrate:
- Enter the CAL menu and connect a SMA male-male cable to port 1 of the VNA.C
- Connect the OPEN standard to the cable end and select "OPEN". Wait for menu highlight.C
- Connect the SHORT standard to the cable end and select "SHORT". Wait for menu highlight.C
- Connect the LOAD standard to the cable end and select "LOAD". Wait for menu highlight.S
- Select "APPLY". Calibration should now be active and you can start performing measurements.

Update: 21 Feb 2025: The customer service is fantastic. The unit I have has an issue. After working with Aursinc, they resolved the issue. I highly recommend this company. They stand behind their products.The firmware needed to be updated and after the obligatory calibration, works perfectly. I use this along with several other devices and build and check my antennas, baluns, un-uns, and filters. Very cool.

I purchased this unit because of it's claim of exceptional dynamic range (90dB+) and I think it can achieve this level of performance. It is well built with a nice metal case and the display is bright and clear. If you need to make measurements on active devices, then this NanoVNA is probably a good choice for you. On the downside, the number of measurement points when operating w/o a PC is limited to 201. Also, it does not play well with the available SW. I tried 3 different SW options starting with the recommended SW but it is very limited and tedious to use (QT). NanoVNA Saver works pretty well but it's UI is clumsy and I was getting frequent crashes. The most feature rich SW for my needs is NanoVNA App, but it would not work at all with this model. I did update the unit to the latest firmware but it still would not work with NanoVNA App. Carefully consider the options before choosing this NanoVNA.

The equipment is well made. I have not had a chance to evaluate the functionality yet, I would expect it to function properly for it' s intended purpose.

This VNA gives you just enough dynamic range to tune duplexers for repeaters. If I can't see the bottom of the notch, I can center them. I have tuned bandpass / reject duplexers on VHF to 900 mhz systems with ease ! Definitely worth it's weight in gold.

This little unit worked ok but it is hard to get it set up to do what I needed.I am accustomed to using the bench version and while this looks like they are on the right track, the display is only fair. Needs improvement.
