Respected sir/ madam

I have query regarding the testing of Nordic Semiconductor ASA- Direction Finding Antenna Board (PCA20054) using VNA (Vector Network Analyser). Please kindly guide me about the procedure of testing this direction finding antenna board using VNA.

Thanking You

What do you want to test?

In case you want to measure on the antenna with a VNA, you need to set the antenna switched manually. Please refer to the schematic for the logic levels in the ANT SEL pins. You will also have to proved the board with 3.3 V.

I want to measure S- Parameter of the direction finding antenna board.
