I found my RFIV box but not the cable, so I wired it up and its working. It seems noisy. Just measuring my load references I get about +/- 1db noise. If I use a bridge, I get a ruler flat line. Also, changing references dont change the noise on the RFIV. The noise peaks are still there so its in the cables or RFIV unit. Granted I'm not using the top of on the box as I haven't found it yet. I have some cheap reference loads and when I use them the noise shifts with their readings. I have to play with it more, of course.
Any config errors that can cause the noise to be higher in RFIV mode?
thanks
Jerry
