HP8566 MANUAL PDF

Temi I hope at least you can see something! There is a way to operate it without the RF unit, by placing a couple jumpers, one to start the unit and another one to select TEST mode. So I cleaned and resoldered it carefully In that case, the manual calls for mahual Manual Calibration Procedureexplained also there. So I decided to get all cards out and carefully clean them and the card cage I am now reinserting them In previous steps, signal keeps inside the graticule but in this one, it is all over the hp of it So unit kind of works!!!.

Temi I hope at least you can see something! There is a way to operate it without the RF unit, by placing a couple jumpers, one to start the unit and another one to select TEST mode.

So I cleaned and resoldered it carefully In that case, the manual calls for mahual Manual Calibration Procedureexplained also there. So I decided to get all cards out and carefully clean them and the card cage I am now reinserting them In previous steps, signal keeps inside the graticule but in this one, it is all over the hp of it So unit kind of works!!!.

The network consists of a resistor and a capacitor. But here you have the tiny work done by the tech: Here you have the display showing the fault: Turn off email alerts.

Here you can see the displays for both adjustments: So, all in all, it seems we are progressing: And, yes, all were OK except for the suspicious one, which was open: Once I got all cards in again, I fired the unit Each stage has to be adjusted while the others are bypassed with those networks.

Jp carefully cleaned the edge connectors, added some contact cleaner, reinserted them and hoped for the best I got a nice peak distortion so it went back to original position. Show only see all Show only. I hope you enjoy it! More to come soon Here you have some pictures of the unit which were put on the eBay listings: Right image come and went by barely touching the cards, specially the A6 one.

All Listings filter applied. Make sure you build the correct one for your vintage boards. Once cleaned, display unit showed a nice test pattern consistently so I decided to connect it again with the RF unit It is the Z-axis circuit. The exceptional frequency stability of the Hewlett Packard A make measurements with a 10 Hz resolution bandwidth easy.

Excellent frequency stability, sensitivity, and frequency-reference accuracy combine to manuaal very accurate measurement of small signals in the presence of large ones.

Here you have all of them, one by one: This is the calibrator signal with several spans: Number of bids and bid amounts may be slightly out of date.

The network is described in the manual. I will investigate what is happening exactly at that moment, as previous steps run fine, in order to try to correct the hp and have the unit finish the procedure. They seem fine enough, as there is none which exceeds 1dB: So now I need to find how to modify that gain Someone had been here before, as there were some test pins with globs of solder.

As kanual was still heating, there were some errors: Here you have a link to a very low quality video of it So I will investigate more about this Format see all Format. It seems gain is too much to be compensated by the auto-calibration system. Here you have all the boards, one by one: Items in search results. TOP Related Posts.

Then I have seen that someone had replaced air filter element with a foam which is clearly not good for that purpose, as it manal airflow a lot. Checking block diagram, I see there is a different circuit from So I have temporarily removed it and temperature has gone to reasonable levels, but still very hot. There is one adjustment in each of the five filter stages. Condition see all Condition.

It is so heavy that engineers at HP had to split it into two units so that they could be moved by a single person relatively easily. Even so, the two units weigh in at more than 50 pounds each. And because it is so heavy, shipping damage is common for these used units if you could buy one locally, it is probably the safest way to go. Mine is also no exception. My units arrived in two separate boxes.
