Nothing...QRP simply asked for RESET readings, so I figured that both ports should be left completely open.

I don't know why the request was made, and I am pretty new to all this...

I posted a new thread because it seemed to me that we might want to discuss what these LOGMAG displays are supposed to mean.

If the ports should be terminated for this test, I can repeat. I believe that I have purchased a good piece of hardware. This request was because I commented that I was having more difficulty calibrating -Q than -H on the same platform. It may well have simply been that I was too new, and reporting what I saw, without understanding what state the device was in.
