Yummy; it's nice to come home after walking eight miles to the Post Office and back and have my eyes greeted with HP and Keithley gear.
Glad you enjoyed. Then here is some more HP stuff too. This is what that Keithley you saw before was sitting on.
This is the HP 89410A DC-10MHz Vector Signal Analyzer
Its quite the boatanchor this one, all 25kg(55lb) of it. This one was showing a NV RAM self test failiure, but all it needed was a new memory battery (Lithium coin cell). Quite conveniently the CPU board that has it can be slid out the back of the unit without taking off the top cover. Same for a few other boards in that computer cage like GPIB/Serial card, Video card etc. From what i remember i found a Motorola 68000 in there.
It makes quite a clicking racket on boot as it goes trough its self test, switching what sounds like 10 relays trough a cycle that repeats about 3 or 4 times. Pretty loud fan in there while the thing still gets pretty hot as it uses 100s of W of power. So you get the full on boatanchor experience right here.
In return you get dual true DC to 10MHz spectrum analyzers and a DC to 10MHz signal source that can be used as a tracking generator, all on a full color raster CRT with VGA output on the back. The ports on it can be 50Ohm, 75Ohm or 1MOhm with AC or DC coupling (Much like a scope). The noise floor goes down to -140dBm and allows a RBW from 3MHz to 0.003Hz. If you also have the RF section (HP 89441A) for it that can make it go to 2600MHz. Or alternatively you can use a IF converter section that lets you tap it in to the IF section of a HP 8566B (22GHz SA) to analyze modulation on radio signals higher up.
Quite a modern bit of kit with the HP badge still on it.

Thats way beyond my level but still a nice bit of hardcore porn, but then thats the real beauty of TEA and GAS, its not always about having the need for, nor the ability to use a piece of test gear, more about saving it from landfill, restoring and adding to a growing collection, amen.

Well i happened to score it for about 250 bucks and is my only spectrum analyzer with a built in tracking generator so it can be quite useful for sweeping the frequency response of things. Its low noise floor and DC friendliness also means you can use it to characterize power supply noise or test audio ADCs/DACs with it.
The signal output port can even function as a arb waveform generator but getting the waveforms to it is not very convenient as its eater floppy of gpib. Tho there is a option for a base10 ethernet card. But i already got a old Tek waveform generator that does it nicely with a comprehensive built in waveform editor (But it takes a lot of electronics to get 1GS/s back in those days)

Jammie bastard! *

Yes I agree, I watched Daves vid and then went on Ebay and purchased this one, I must say its an extremely handy tool, makes light work of removing parts for testing, replacement or just harvesting, hand pumps and desoldering braid, forget it, get one of these, job done.
Absolutely, I've got the same one twinned with a soldering station and it's great - I've even found that it beats wick for cleaning up SMD pads, I just drop a dash of fresh rosin core solder onto each pad, then suction it up and voila, beautiful clean, flat shiny, tinned pads in no time at all!

That's a nice score, Berni! And nice job on getting that 617 working — a convoluted power situation, indeed.
Anybody here think of a rational use for these...or should I consider them harvestable?
I'm sure all those HP fan boys would take em of your hands for a consideration

Kind of hoping so. This is 1960s stuff, with very low bandwidth. I hate scrapping stuff, but I just can't justify the space here.
WastelandTek, it's helpful to add your country in your profile so folks have a sense for things such as, in this case, potential shipping costs when they see your country's flag in your posts.
Those two units look to be in great condition and would work nicely for audio. The 353A patch panel is often found in a three-instrument enclosure between a 200-series oscillator and 400-series AC voltmeter.
Oh what is this?
I've got three emails that announce delivery of items i bought recently. I caught myself having a guilty conscience about that and at the same time noticed thoughts creeping up how to hide that from my wife. There's still no abbreviation for that..
The last instrument (3437A) is still residing (and being serviced) on the floor of our living room because I temporarily ran out of space at my workbench.
She'll have to cope with it somehow. I hope that doesn't hurt me too much.
The seller of the 3335A is really fast and the Agilent 8110A from across the pond is now in germany ..
edit: Just received the announcement of the desoldering station being delivered tomorrow, too. *gulp*
I find Isopropyl wipes get almost anything off plastic and rubber cases.
I've finally got my hands on some 70% isopropyl, as I was out and every shop seems to be too, but no dice. I don't know how carefully strapping a meter into a soft case and putting it aside can leave marks, but they are on there and aren't coming off.
All the rubbing and scrubbing seems to have lightened the marks, but also affected the surrounding area with some very minor scuffing. It seems stupid to spend as much as another cheaper but properly nice meter would cost on some spare parts, but it seems I'm going that way. I just can't stand this.
For practical bench work* I acquired an Oltronix B300D Power Supply today:
The offer was too tempting..
It's time too end the phase being off and to start going to work again. Being off with just one arm broken (and being capable to use the other arm for ebay) is just becoming too expensive.
And I don't know how much longer my wife tolerates packages to be delivered on a daily basis.
*- having ones hands in electronic equipment or on bare circuit boards doesn’t require gear with GPIB.
I reschedule my deliveries for when she is out

Sounds good indeed.
Problem on my side is: We're both employed and I'm longer hours at work than she is.
Have them delivered to work and then you can bring them home and sneak them indoors when the coast is clear. One thing crosses my mind with all these acquisitions is that I'm sure the national reserves at The Deutsche Bundesbank must be dwindling rapidly

When I was married, I got the stuff delivered to work. (Mainly because someone would be there to receive it, but keeping things on the down low from SWMBO was an added benefit...)

Bad timing fail for me in that department. My HP supply is due to arrive on Monday. She’s out tomorrow and in all day on Monday and I’m out.
