Hi,

I have a working Madell ML-859 pump station. Does not include desoldering gun or accessories. $10.00 plus shipping. Please respond off-list.

Hi all,

Really strange. I feel like HP made the 3324A later than 3325A.

I saw the pictures of 3324A that having a dot matrix VFD display and new "HP logo", so 3324A seems to be a generator later than 3325A.

Hi all,

My 3325A has the attenuator board marked as "03325-66523 Rev B" which uses 4 yellow "PRINTACT" Latching Relay (12 BW4LD).

I think Patrick's attenuator board is the newer "03325-66523 Rev C" which used the relay made by Aromat (Japan). I think Aromat is being merged with the Japanese giant Panasonic.

It seems to me "Rev C" is a cost down version because it is not longer having the gold plated PCB.

P.S. Really wanted to know the model number of the Omron relay used to replace the original Amron relay.

I have a 8601A for sale in very nice shape as well as a tektronix 465/DM44 and 453 for sale. someone suggested I post here. would be happy to send pictures. Thanks

Hi,

I have 2 sockets coming, Thanks to all.

Hi all,

My trusty HP-8640B (the first unit I got years ago) has suddenly stopped working :-(. I used it last time yesterday night and worked fine but today, upon powering it up, it shows an all-zeros blinking display and does not generate any output at any frequency nor setting. Any hint of what is happening? (BTW it is NOT a pushed-in LOCK button problem)

Thanks for your help!

Regards,

JOSE

Hi,

I wnt to use my IP-5220 to run power test on an SC501 and found the isolated outlet bad again. I had noticed earlier that some power cord did not make reliable contact with this outlet. I took the outlet out and found the power pin was smashed flat. Of course I damaged the socket body removing it from the chassis. Not a problem thought I. My manual says the part number is 434-148. No vender number though. Much to my surprise I have not been able to find a replacement part. The socket fits in a 1 inch square hole. The only thing I found fits in a smaller rectangular hole. If someone knows how to find a replacement please let me know. An interesting sidenote, Whoever built this unit did wire it per the instructions. They wired the isolated(3Amp) in parallel with the non-isolated(10A) socket.

Perhaps one of these connectors will be what you need.
From www.mouser.com, catalog numbers 693-4300.0701, 693-4300.0702 or
693-4300.0703

Cheers,

Leviton 1374-1 is the socket - had ne go bad in a power strip. Fits a .95" x .95" square hole. Add a -W if you want it in white. 5 bucks max at most industrial suppliers.

Hallo Guy,

we are talking about the IF section PowerSupply (85662A) yes?

I concur with Jose, and can add that the +15V is the one you should concentrate on, because this is used as reference for -15V and 100V

Besides the foldback current limit there is also a thermal shutdown circuit influencing the 15V supply.

Marc

Hello Guy,

I know this is a very general message but I think
it may help you... those HP multi-voltage
supplies usually have one of them as a reference.
If it is bad, all of them will show wrong
voltages. I am guessing the reference may be the
100V one (if I recall it right, on HP-141 series
it was that way, but of course they are ages appart)

Have you followed the Service Manual PS
troubleshooting section?. For sure it will be
clear there which one is the reference PS.

If I have some time later, I will check the 85662
Service Manual but now I am in a hurry and must
leave, so sorry for this so-generic message.

Good luck!

JOSE

the Power supply 100V is now 60 volts and the

Tim,


I do not have choice. The prices to get a good working SA is outrageous for my limited budget. I have been very glad I can afford to buy a broken SA.


I only wish to restore at least one of the broken HP8565As first. Then, I wish to get the display digitized so that I can get rid of the CRT and that I can capture what has been measured and displayed on screen. No matter what I will invest, I believe will be a lot cheaper to get a working SA.

Thank you for giving the tips about EMC. Actually, I have bought that book very recently for my current job as an electronic design engineer at a R&D company.


I just measured the display dimensions. It is a 5" display. Should be easy to find a replacement, provided that I will need to design the circuits behind the LCD module first.

There sure to be problems when I start working with this project. I am not denying the fact that there are always problems for some project no one has ever attempted or done. But I will not be getting anywhere if I only talk about my plans and worry about all of the possible problems but do nothing about them. Setting a high goal may not guarantee success but will land me at a higher ground than where I currently am.


I do not have much expectation about the performance of this HP 8565A because it is already old and has been beaten up.


Currently, I just need some tools for me to work on some RF projects at home. If I have to get accurate results, I will then bring my projects to test with those modern test SAs at my company. So, accuracy or stabilization may not so important for me.

Amos

Yep - might have to read up on the EMC - have a google for Henry Ott.
Be careful you don't over invest in the SA. They are good but the YTO
drift will still be there. If your tube is really suffed you can always
use the signals on the back for your CRO or pc sound card. A good pro
stereo sound card with 24bit digitising would do a good job. Software
required.
One thin that could be worth investigating is auto stabiliser circuit.
It locks to the 2000th harmonics of a 1MHz VCXO - changing this could be
intresting.
Yes those lcd panels are too expensive - cheaper than a new 8566b. They
hook into the video display and read the vectors into a raster. The
8565a is a fully analog SA with a bit if digital to control sweep and
display parameters.

Tim,

This email is to respond to your earlier email about having some VGA kit to replace the CRT.

I have an idea. Since all the display section does is to take the signal to be display (y-axis) and sweep the screen with sweep signal (x-axis), I can make up a digitized circuit that does the same thing as what CRT will do and connect the output to a LCD module that fits right into the window of HP 8565A, I can have a cheap solution for replacement of CRT tube circuit.

My idea came from here:

.

About the normalizer part. I am thinking about build up something based on the same design of normalizer in SMD and place the circuits inside the large cavity where CRT is in. I can then have all the functions I need in the same box. I am thinking about changing the weird AUX connectors to some easy to get connectors from Digikey (same pin numbers, same dimensions.)

Hi Amos,
Try this link


My understanding is this: The 8565A was basically squeezing a 10
MHz-22GHz 141 specAn into one small box. It has a YTF in front of the
mixer to remove harmonics and noise. It is a completely analog
instrument with some early discreet logic for control.
The 8569a/b is basically the same rf section with the analog storage
tube replaces with a low speed digital oscilloscope. This is done to
allow the slow sweeps to be digitised with the slow ADC technology
available at the time, while the higher frequencies required for zero
span could bypass this for display on the tube as a cro.
It is not practical to convert an 8565a to and 8569 by replacing the
display section. This was accomplished with the 8750 normalizer..
The rf section is slightly different with better dynamic range and noise
floor - but not too different.
If the display or tube is shot, you could use the normalizer and a
normal oscilloscope. Slow sweeps can be captured woth a pc sound card
and there are some projects on the web.

Good luck

Tim

Hi Eugene,

hadn't seen a 3324A before, interesting.

Looks like a redesign with newer components, and not much change in the specs.

The diffs I see are:

- sweep: the 3324A has multi-interval sweep
- resolution of the 3324A is 1mHz, for 3325A it is 1uHz
- I don't see AM/PM modulation on the 3324A

To complicate matters, there is also a 3325B:

- looks like the 3325A
- has 1uHz resolution
- has multi sweep
- has AM/PM modulation
- has an internal AM/PM modulation generator

Marc.

Or, if you prefer:

ftp://ftp.bluefeathertech.com

If you're sending something for upload, though, you'll need to send it
to me in an E-mailed file attachment.

Thanks.

John,

There is already one there. It is a .RAR file.

On the 'Manuals' page, search for '8350B'. You will find 'HP 8350B

I did not upload it but it should be the same. If you have any
problems, I can send you mine as a .ZIP.

Jon,

I have the images and, IIRC, I put them together in a .ZIP file that
I emailed to someone on the list several weeks ago. I believe he was
able to unzip them and burn a set of EPROM's to upgrade his 8350B.

I would be happy to send that to you if I can just remember which

Just curious, why would you want it on a CD?
