Hello group,
After year of a good service our HP 8565E is getting some illness. I have tried to look to 8560x service manual which was available, but the error numbers, which the 8565E gives are not there.
I am getting following error:
ERR 340 SAMP AGC
ERR 338 LOMA AGC
ERR 319 WARN COA
ERR 351 setrl
some of the texts could be wrong read, the errors display one over each other and they are not easily readable.
The frequency display seems to be unstable, jumping erratically in the range of 100Mhz around the correct frequency.
The errors are seen just after switch up, when displaying full sweep, and after some time it is when greater span is used (above 100MHz), below that span it seems to be stable.
I suppose it is something with YIG or frequency synth....
I will appreciate, if somebody could interpret those errors for me, or even better, if somebody knows a reliable source, where the service manual could be bought or downloaded.
I have looked to Artekmedia, but I have not found it there.
Thanks for reading and will be gratefull for any info,
OK1VAW, Vojtech, Prague.
