Re: ebay vendor "hstate"?
Thanks Dan,
I tried not to cast any aspersions with my post.? I probably should have waited till I got a reply from you.? Unfortunately, I've been punked a couple of times in the past year on ebay and I thought, here we go again.? Apologies if anyone got a bad opinion of you as a result if my post.? You did what was necessary.
I'm looking forward to getting it.? My 8640 just can't do what I need for this measurement.

I recently obtained another 8642A. It works fine, and even is in calibration, but it is obvious it was made with parts from more than one unit. The serial number label says option 002, rear connectors, but it does not have option 002. The connectors are on the front. I do not really care, as I said, it works perfectly as far as I can tell and it is within a couple tenths of a dB in output level to my other one at every frequency and level I have checked.
My question is, when options are installed or removed by a third party, should the label be updated? On the next CAL, can the option 002 just be blacked out? Mark

Re: Looking for 8563E Schematics for A2 and A6
Hi George,
The most reliable quality source of course is Dave at Artek Manuals. But like many HP instruments there were variants that used modules that were electrically equivalent. So Dave only has what he has access to or manuals that people have loaned him to scan.
The A2 and A6 modules are different enough from the ones depicted in all of the clips that I have or have seen. .It appears that the 08563-60020 power supply is a signal PCB design that is very different from the later 08563-60094 version that used individual modules for regulation. The A2 card has a reset generator circuit that is also quite different than the other variants. It is the combination of the power good signal from the power supply and the reset generator on the A2 board that I want to verify and troubleshoot, In order to do that it obviously would be best to have the correct schematics.
Best regards,
Sam W3OHM

For reasons that I will not go into I have recently been spending a lot of time trying to find schematics for HP switch mode power supplies, what a frustrating experience.
What I can say is that the 08563-60064 schematic can be used as a basis for fault finding other similar power supplies.
The input stages are common in a range of models, the problems occur in the control circuits.
A word of warning, do NOT work live on these SMPSU without an isolation transformer in the incommoding mains supply and most, if not all, require a minimum load to operate. There are lethal voltages present (370VDC at very low impedance).
I suspect that you already know this, but, if you do not I can provide the correct CLIP numbers for your serial number.
Where O where do you get the CLIP's from?

I have the schematic and layout for 08563-60064 power supply is that will help. You might try 8561 or 8562, very similar.

FS: HP RF Signal Generators
Hello All,
I have for sale three HP ESG RF signal generators. I have checked them all for basic functions (frequency, power, and analog modulation). I have not tested the digital modulation modes in the ones that have it. Because I have not checked out every function or calibration, I am selling all AS-IS. These have all seen some use with dings and scratches in the case and panels. LCD displays are all good.
I can deliver to the Berryville Virginia hamfest on August 6.
1. Agilent E4431B ESG-D - this is 250kHz to 2 GHz, with digital and analog modulation. It has options 1E5 (high stability time base), UND (dual arbitrary waveform generator), option 1EM (rear connections. The RF output has been moved to the front). Price is $750 plus shipping.
2. HP E4421B ESG - this is 250kHz to 3 GHz analog modulation. It has option 1EM (all rear connections - nothing has been changed.) Price is $600 plus shipping.
3. E4431A - ESG-D2000A - this is 250kHz to 2 GHz, with digital and analog modulation. It has options 1E5 (high stability time base) and 1EH (baseband generator). This has all front connections. Price is $650 plus shipping.

Re: ebay vendor "hstate"?
Thanks Jeremy,
Something happened in my order that just didn't make sense compared to his feedback, so I was a bit concerned.? But, he's already taken care of it, so no worries.? Sorry for troubling the list.

FS: HP 8901A Modulation Analyzer
Hello All,
I have for sale an HP 8901A Modulation Analyzer. It is in nice shape for its age.
The 8901A measures AM depth, FM deviation, PM rate, frequency, and RF power. The frequency range is 150 kHz to 1300 MHz. This unit is working (i.e., it agrees with the power, frequency, and modulation that my signal generator is putting out) but I am selling as-is because I have not checked every function and cannot guarantee calibration.
Price is $175 plus shipping (this is really heavy so shipping will be expensive.) I can also deliver to the Berryville Virginia hamfest on August 6.

Hi everybody Has somebody the schematic diagram or service manual of this old power supply. 15V 1.5A. Thanks a lot Dominique

I have no way of knowing for sure, But I would bet against it
Hakan can chime in as he has the most complete ( that I know) set of

Re: E4406A Input Attenuator
As a follow-up, I removed the relay from the RF Board and then just bridged the Cal & RF input pads using a piece of wire. The unit passes its self-tests with the wire bridging AT1 (pad 2) and the 50MHz Cal pad (pad 8) , it also shows the RF input very close to what the signal generator is putting out (only 50Mhz as I'm using a piece of wire held in my hand).
The one strange thing was that the control voltages for U38 were +/- 9V rather than +5v & 0V, I'm not sure if that is indicative of problem further up the chain that could have been causing the relay to fault.
