Hello,

I appreciate the earlier reply. What are the limitations to the voltage offset of the second channel when running two channels off of the same signal? (see previous message) That is, if the first input is DC zero centered, can the second input be DC offset relative to the first input? In other words, I need the most accuracy at one extreme of the signal output, so I want the second channel to be DC offset about -10V from the first.

Thanks!

-Steve

Hi,

You are not able to do this type of offset with Picoscope.

The only type of offset that can be done is 'Offset Null', which allows you to work at low input voltages, and remove any small offset on the ADC input. This is done by shorting the inputs.

Best regards,
