Greetings Everyone. I have a question for those of you that have spent some time with an HP 8566B or similar Spectrum Analyzer.
I've noticed a side to side jitter on the active signal trace from time to time, up to 250 KHz each way (!!), and an occasional momentary drop-out of the trace. This is only periodic, and seems to correct itself after a few minutes, or if I do an instrument preset, or re-configure the SA from the controller. The phenomenon seems much more stable when viewing a span under 5.0 MHz. I have the 462 Option and have done the cal-check on the 6dB resolution band-width filters, and all other self-cal routines I can. I've also checked and changed most of the interconnecting cables. I also have the Preselector and Quazi peak adapter, but bypassing these doesn't seem to change the problem, and neither does playing with the SA and Video bandwidth settings. I thought I'd pass this on to see if anyone out there's 'been there done that', and have any ideas on troubleshooting this, before I find myself with some down-time and repair bills I can't afford right now. Thanks in advance if you can drop me a line. Best regards, Rob. Protocol --------- This message is coming from the emc-pstc discussion list.
