And if you push the bypass button?? the problem goes away? I've seen similar but it was another manufacturer.

The data is showing evenly spaced discontinuities at 44MHz, 58MHz, 72MHz, and 86MHz. There may be others at higher frequency but if so they are subtle. By "discontinuity" I mean the data takes a sudden jump upwards, with the magnitude of the jump being different at each frequency. The testing is being done with the typical HP 856XX rack that everyone has. Does anybody have any ideas what the problem could be? I suspect our aging HP85685A pre-selector, based on the nature of the issue we're seeing, and on its history of unreliable operation. Thanks for your help, Jim Eichner, P.Eng.
