Re: OT: Wanted: .pdf's of SAUGAMO Silver Mica dipped molded Capacitor ?---? Data Sheets or Catalogs ?

 

Have you looked at mil-prf-39001 document? The CM158300J would probably be the military part number.

Some precision here would be appreciated.

Just to be clear, is this company called Saugamo or Sangamo? I remember Sangamo very well, a well established maker of capacitors and watthour meters. I never heard of Saugamo. Is Saugamo a mis spelling or mistyping of Sangamo or a separate company or a changed name or what? Some precision here would be appreciated.

Sangamo and Saugamo both seem to be the same company in springfield illinois. I think maybe the county and company name changed at some point.

Re: HP 3852A firmware update issue

Maciej,

Excellent to hear, glad it is all working!.

?

Also I checked my other 3852A and it also has 4.22 Roms in it.

I’m hoping to sell this one. With switching, i/o, ?cards and 5.5 digit dmm.

?

Regards

Nigel

Nigel and all.
Got my unit running 4.22. Used w27C512 for U58 and U58 and AM27C256 for the rest.? Self test reports no errors. Now I need to figure out why I don't see A23 signal anymore on the logic analyzer.?

Re: 8557A/8558A Switch Board Assembly - Contact Fingers

 

The contact finger repair on my 8557A is complete!? I am pretty close to getting this repair wrapped up.? I now have the timebase working and pretty sure the frequency and amplitude switching is working, however, I still need to figure out the orientation of the knobs on the frequency/div & bandwidth/resolution stacked switch.? I was hoping someone who owns one of these units could tell me the settings of the frequency/div & bandwidth switches when they are set all the way clockwise (or counterclockwise).? I would greatly appreciate it!

Two months passed between when I first diassembled the front end of this plug-in and now.? So I forgot how the switches were oriented.? I apologize if this is a dumb question or that it should be intuitive.? I have never used a spectrum analyzer before this repair and never had the 8557A when it was in working condition.??

This repair definitely tested my patience.? I had to diassemble and reassemble the front at least 4-5 times to get things right so far.? But I think I finally have it right!? Added some photos.? I believe the peak is just LO feedthrough because there is no signal applied.??

Thanks for everyone's help with this!

If I may be forgiven for mentioning this for the second time in a few weeks... I just went through this exact same repair with the 1GC1-4210, made my own board, and have traced a (very limited) area around the divider, documented here? :

Also have a YT video about this E4402B that should be easy to find.

Could you tell me what you see? in the System (2) -> Show Hdwrd page, at the line “50ohm 3GHz input” ? I'd like to compile a list of hardware revisions and correlate to the type of divider IC used.
