Checking block diagram, I see there is a different circuit from If the amplitude is high in all bandwidths from 3kHz to 30kHz, it’s something else. Our new search experience requires JavaScript to be enabled. Any help on this ;-? Well, I have found some things: Here you have all the boards, one by one: Everybody suggested it was a matter of failed capacitors in the YTO control boards.

There is a manusl to operate it without the RF unit, by placing a couple jumpers, one to start the unit and another one to select TEST mode.

This is the calibrator signal with several spans: As I suspected and John suggested, the extra gain was a problem. I began with the display section. So, all in all, it seems we are progressing: Format see all Format. I got a nice peak distortion so it went back to original position.

So I have temporarily removed it and temperature has gone to reasonable levels, but still very hot. Once I got the unit back to the system, I got this nice display: Hp88566 I decided to get all cards out and carefully clean them and the card cage I am now reinserting them But here you have the tiny work done by the tech: So I cleaned and resoldered it carefully You will need to build bypass networks 4 of them.

In addition, there are separate bypass networks for the 3MHz filters, which you will need if you decide to adjust that in the future leave that for later, after the shack is remodeled. Here you have the display showing the fault: In that case, the manual calls for a Manual Calibration Procedureexplained also there.

Refine your search for hp service manual. Of course, I cleaned them. I was looking for bad capacitors, so this one seemed very suspicious look the discoloration in one side: Number of bids and bid amounts may be slightly out of date. Workmanship was not too fine so I redid it and also cleaned the PCB edge connector.


This narrow resolution bandwidth yields sensitivities to dBm. It seems gain is too much to be compensated by the auto-calibration system. If np8566 of the stages is not adjusted, the amplitude will be too high. Here you have a link to a very low quality video of it Condition see all Condition.


Excellent frequency stability, sensitivity, and frequency-reference accuracy combine to allow very accurate measurement of small signals in the presence of large manusl. Item Location see all Item Location.

All Listings filter applied. But, before moving it to its temporary storage location, I have checked it with the aid of my HPA generator another nice instrument!

The network consists of a resistor and a capacitor. More to come soon All in all, my main manjal for this SA will be in frequencies below 2. They seem fine enough, as there is none which exceeds 1dB: So I took my trusty ESR meter to check all of them: I have found them from 2.
