About NanoVNA V2

NanoVNA V2 is a low cost 3GHz T/R vector network analyzer designed by HCXQS in collaboration with OwOComm. The V2 hardware is a new from-scratch design and is not based on the original NanoVNA by edy555. Compared to the original NanoVNA, V2 does not use harmonics for measurements and achieves higher dynamic range.

Buying

There are several manufacturers of the V2 and resellers on Aliexpress, Tindie, Taobao, and eBay. Performance varies.

Basic usage

VNA basics

A VNA (Vector Network Analyzer) measures the frequency dependent reflected and transmitted power of a high frequency network (RF Network).

The NanoVNA V2 measures the following:

• Reflection coefficient: S11
• Transmission coefficient: S21

The following items that can be calculated from these can be displayed:

• Return loss
• Insertion loss
• Complex impedance
• Resistance
• Reactance
• SWR

Required components

To use the NanoVNA V2 for one port measurements (e.g. antenna impedance), you will need the following:

• NanoVNA V2 main unit
• SMA cable, male-male
• Calibration standards: Short, Open, and Load

Performing measurements

The basic operation and menu structure of the NanoVNA V2 is identical to the original NanoVNA.

• Configure the measurement frequency range:

  Select STIMULUS > START and STIMULUS > STOP.

• Calibrate:
  1. Enter the CAL menu and connect a SMA male-male cable to port 1 of the VNA.
  2. Connect the OPEN standard to the cable end and select "OPEN". Wait for menu highlight.
  3. Connect the SHORT standard to the cable end and select "SHORT". Wait for menu highlight.
  4. Connect the LOAD standard to the cable end and select "LOAD". Wait for menu highlight.
  5. Select "APPLY". Calibration should now be active and you can start performing measurements.
