Thanks for the help with the previous problem, but now there is a different problem. The E8257D is an option 550 and when the software tries to run the high band adjustment it fails. I've noticed that when it runs through the -3dBm test it runs very quickly and the power meter will drop dramatically in the higher frequencies (usually a drop between -10 or -11dB above 30GHz), but when the next to tests (-13dBm and -18dBm) run, they are much slower and show no significant drops. I've run something similar by hand and have not seen any drops that badly. The equipment being used switches up, I consistently use the 8487A power sensor, but I switch between the E4419B and the N1914A power meters (same problems with both meters).
