We are applying 3.3VDC to VPS, which gives about 3.2VDC so VPI and VPSD. After using a spectrum analyzer, we are able to see an output signal from the board. Our problem is now that we are not seeing the expected gains. When we set the software parameters to all of the highest gains, we see an output gain of about -8dB, when we are looking for 60dB. When we lower the gains, we see the board respond, for example, when applying a 30dB gain to the board, we get a -38dB output gain.
Thanks,
Bill
