Output attenuator for P1.7
In Leiu of the remote attenuator setup as in the original I have a 4 stack DAVEN attenuator that I want to re-resistor for use with this 1.7. What value do I need to look towards building to equal the impedance of the original 1.7's attenuator?

I use a 10K ladder on the output of mine with the gain resistor at 700ohm and the input pad settings @ 9.7 dB.

Thanks Mark! I had a sneaking susposcion based on the original iunits output impedance that it needed a fairly low impedance attenuator.
