Are there any test points on STEVAL-D25R16B for me to connect S11 of NANOVNA to?

Hi, 

May I know the available test points on  STEVAL-D25R16B for me to connect S11 of NANOVNA to ?

Also, which of the register values (space a and b registers) are essential to set the board to high impedance (VNA mode) before connecting the nanovna to the test points while the board is powered?

Thank you!

Best Wishes,

Cindy

Hi Cindy,

please check the proper antenna matching app note for details how to perform such measurements.
