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

Dave et all These manuals are all for the "mixed technology" ( Tubes + Transistors) version of the 410C The all solid state version started at serial number 0982A22339. The Manual Lee needs is

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

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

Max - not the 8551. It came with an 851 display on top. you can google it. will

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

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

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).

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

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

Thank you for your response. I would prefer both AM, FM and SSB but economic compromises may have to be made. FM at a minimum. As to the frequency, I was assuming that I would be able to use

It's not free, but PrintCapture http://www.printcapture.com/ does exactly what you are looking for. Based on my experience, it's an excellent product. I bought a copy and use it with some older HP

Hello Community, many HP instruments (spectrum analyzer, oscilloscope) have a dedicated plot menu for outputting vector trace data and a separate print menu for outputting list data, texts or raster

Once the BWO has been replaced with the YIG upgrade kit thats no longer an issue- does this one have that upgrade applied? 73 Dave, ZL3FJ Christchurch, NZ

What frequency range are you looking for? I usewd a DEI R-1037F telemetry receiver on the 227 MHz IF output of an AIL 757 SA. Do you need AM / FM / other? -John =============

I am looking for a shortwave radio to use as a demodulator for my spectrum analyzer, so I can listen to the signals I see. I don't have a shortwave receiver right now. Can someone make a

I've used a piece of clear tape on the inside edges of the c-frame - works great. Steve Sent from my iPod

I have decided that I would prefer to have my GPSDO in a retired HP full width, 3-1/4" high enclosure so it can go in the stack with all the other stuff. Does anyone have a beyond repair instrument

Another problem with the 8551 (besides its' weight and therefore very high shipping cost) it it's use of a BWO. They have a limited lifespan, and new old stock are like hen's teeth. I got a nice one

Hi Jarmo, maybe you have one cell stuck, due to magnetization of the small actuator... Can be locked to the ceiling of attenuator case. This appened to a good friend of mine, Art iw7jwy. So the
