Hi everyone,
the nanoVNA V2_2 (SAA-2N) has finally arrived. I wanted to use it to fine tune the four-cavity filter (BPF) at 2200 MHz, I was thinking of connecting CH0 to the 2nd LO input of the TR503 and the CH1 to the IF output of the oscillator at 2095 MHz, or it is better to connect the CH1 at the mixer output, by disconnecting the semi-rigid cable from the input of the oscillator at 2095 MHz ?
First of all I put the cables and adapters together and connect them between CH0 and CH1 and perform the calibration of the nanoVNA by setting the center frequency to 2200 MHz and the span to 20 or 30 MHz.
Honestly I am not very familiar with VNA, if you have any advice and suggestions I would be grateful.
Thank you.
-- Cheers
