Isolation

Post by Guus » Mon Apr 27, 2015 6:34 pm

Dear forum members,

I was wondering if the Red Pitaya has isolated RF inputs and outputs? That is, if they are all referenced to the same ground or if each input or output has its own ground? I would need to measure voltage on the input and across a random resistor, thus it should not short out through ground on the device like an ordinary scope would.

Kind regards,
Guus

All 4 RF connectors share a common ground. The analog ground is also shared by the input and output circuitry of the channels.
