I have an HP 8563E with S/N 3301A00591, I am getting a Err 317 319 334 351 353 356 459 561 562 564 565 error after the SA boots up. Anyone have this problem before? Can someone give me some guidance to fix it?
Please any help greatly appreciated.
Please any help greatly appreciated.
Have you looked at the list of errors for the 8563E? The first errors are YTO errors; 317, 319, 334 etc. Do you have another spectrum analyzer to check if there is any output form the YIG oscillator?
If the YIG is bad then you could get this type of errors. Often when one error is found there will be a lot of other errors in the list, so it's important to figure out the origin or first error since this will trigger a lot of new "errors". If you're lucky it's the control of the YIG that is bad.
First - be very careful when you open the spectrum analyzer. Deadly voltages are present so please DO NOT do this if you don't have the proper skills!
Check the voltages on the YIG and be very careful when you are measuring so you DO NOT short circuit anything! If the YIG is broken old ones can sometimes be found on Ebay, but before you buy any please check if there is any power output from your YIG! You do that with another SA.
