3562A Analyzer
I've been restoring a 3562A analyzer for a couple of months I bought it off ebay relatively cheap as it had some water damage. It's working fairly well now, but I have a couple of startup errors, one

Re: HP 8551 Spectrum Analyzer FS or trade?
In theory, but I have yet to find one with the YIG mod. Or, to be more accurate, most people selling them only have the main unit, or it and a display, but none of the cables or filter- they don't

Re: HP-IB / GPIB Printer Emulator
I found a distributor web site in Germany that shows the product: http://www.stcsweb.de/eng_oldiesmicroplot50a.html I also remember that it did a good job, except that it didn't know what to do

Re: HP-IB / GPIB Printer Emulator
Martin, Before I found 7470.exe, I used to print to a laser printer with a standard parallel port. I used an adapter made by a company called "Intelligent Interfaces". I think it was called

Foam conductor problems
I've added some pictures under "3561A repair" to document a problem with my SA. All the electronics check out after replacing some parts but some of the buttons and most of the LEDs were not working

Re: 3457a on the way
I had one, and it was a good meter. I sold it to a friend, who has never used it, and now I need it, so he is going to sell it back to me. Neither of us can remember what I charged him for it first

Re: DIY: Repair of HP Step Attenuators
Measure the coil resistance and drive voltage.? It may be that the drive is weak and it's not getting enough coil current, either due to coil resistance increase or drive signal decrease. Bob

Re: New Spectrum Analyzer Discussion
I think maybe you misunderstood my posting. Or I didn't write it well. I mentioned I have an HP and an avcom but they are not what I am discussing in my posting. The spectrum analyzer I am talking

3457a on the way
So I have a 3457a on the way that passes the self tests. What are the odds of it actually working when I get it? What should I look for as a general failure for these devices? I always assume

Re: New Spectrum Analyzer Discussion
The prices I see at: http://www.tscm.com/avcom1.html make this an expensive spectrum analyer. You were lucky to get one for $250, if the basic price is $3375 I think I'd rather keep my HP 70000

New Spectrum Analyzer Discussion
I see there is some discussion about an older large spectrum analyzer. I thought I would share my experience with a new very cheap but quite useful spectrum analyzer. I have an HP 8558B and an Avcom

I'm one who works with the dark side of the Force, that is, digital. I have no spectrum analyzers at all, although it might be nice to get one one day (and I am sufficiently space limited to not want

Re: DIY: Repair of HP Step Attenuators
All, I wonder: I have a sticky microwave relay in an HP 8593A. If the relay has been closed (ie for LOWBAND) for about five minutes and is opened, it won't close again unless it's had a chance to

Re: What is a good shortwave radio to use with HP 8568B SA?
A converter with a software defined radio does sound like a good idea – if I can find something that will work with my Mac or linux machines, that sounds like an easy way to go. I will look at the

Re: What is a good shortwave radio to use with HP 8568B SA?
Duh! A USB SDR dongle with an up converter! The thought never entered my mind. What great way to go. I was thinking more strictly hardware (with my limited mindset). The funny thing is, I have one

Re: What is a good shortwave radio to use with HP 8568B SA?
Pretty much any shortwave radio that tunes 21.4 MHz and the modes you want should work. Sensitivity is not an issue as the IF output on the rear is a high level (you'd likely need an attenuator).

Re: What is a good shortwave radio to use with HP 8568B SA?
Try one of the emergency radios with AM-FM-SSB. Or, a $20. RTL-SDR USB dongle on your computer with a Ham-it-Up HF converter between it and your HP 20mHz output. All-mode 0.5 - 900+ mHz plus a bunch

Re: HP 8551 Spectrum Analyzer FS or trade?
Hi Daniel. If I remember correctly, and more and more lately I don't, the 8551 came with different front end modules for different frequency coverage's. What is the frequency range of yours? If it
