Hi experts,
I am quite new in this forum.
My situation: I´ve got error messages on the HP8563A, #301, 317 and sometime 334.
I have bought a used one in UK and then replaced the existing one.
I have passed the routine of YIG alignment in the service manual, but I don´t get the lower frequency position with 3.02 GHz adjusted with the spindle poti.
So I put the jumper on A14 back to it´s original position and I tried (try and error) to get at the lower band a sweep from 10 kHz up to 2.9 GHz, all the time monitoring the LO output with another SA. Frequency flatness is quite good and also the measured LO-level of apr. +14dBm. No error message is present.
By pressing full span, I get 301 and 317 error again. what are the correct values in the frequency analysis menu ?
Has there any calibration code to be typed in after having changed the YIG ?
I ask for good guidlines from people, having had the same problem .
Kind regards from "cold" germany
