HP 9100 9100b Calculator actual HP schematics and instrument logic-flow chart
hi, I found the following actual HP 9100b schematics and instrument logic-flow chart to be very helpful in troubleshooting the HP 9100b Calculator. { the actual downloads might take some additional time to load, but are good }. These, along with Tony D's "pencil"? schematics, are good. A number of other HP Calculator, Computer manuals, schematics, etc. are found in the 3rd link { below }. rick

Re: 8341A *restoration adventure*
RubenRubio -
Yes it is a bit more difficult, but basic measurements can be easilly made with what you have - just be careful of the power levels.
Based on the diagram you have shown, you need to set the 8341 for 100 MHz output, them measure the power out of the 3.8Gig oscillator, and the power output from the band 0 power amp. You could also check the low band power amp ouput at 1 GHz, but the 200 mHz measurement should be enough for diagnostic purposes.
Output for the high band power amp can be done at 2.3GH, 4.5GHz, and 6,9 GHz - that will give you a good idea as to the YIG+AMP performance.
If you find the 3.8GHz oscillator is working, and no output from the band 0 amp, check the input to the amp, and then the input to the modulator. Straight forward but tedious with only a power meter.
Yes - An an 8566A or B is an excellent choice, They are my favorite spectrum analyzers - and they are repairable - some of the laer units are not as repairable.
Cheers!

Yeah that's for sure
In the service pages of the RF section I hope to find those power figures of the modules, yesterday I was reading some pages about this section and I studied the block diagram, and the lack of output power in amplifiers or oscillator can result in this behavior. Until I can get a spectrum analyzer (hopefully an 8566B, but they are very expensive) I will keep working with what I have. The adjustments ask for an ancient scalar network whatever test set I don't want to buy...

Re: Removing the Adhesive From Hell
Brad, I feel your pain on the dried masking tape adhesive, just be glad they did not use filament?reinforced packing tape as that is 10x worse of a mess to deal with. I have seen where applying a light coat of WD40 to the adhesive and letting it sit for like 15 minutes?can work quite well(it's great for removing price stickers and most permanent marker stains as well)l, then it can be wiped off and cleaned with denatured alcohol.? As always try on a non conspicuous area first.

Hello--
I'm restoring an older piece of equipment that was festooned with
tan-colored
masking tape. I'm able to scrape away most of the crumbling tape-- but
not its adhesive.
Applying Goo-Gone works but not well (softens the glue) snd it doesn't
remove
do a good job of removing adhesive from one's fingers.
Recommendations are welcome.
Thanks, and 73--

Re: [TekScopes] Removing the Adhesive From Hell
If the part can withstand the heat, I've found that pouring/soaking in boiling water will help loosen some adhesives. I've used that recently on some residue on metal parts. Goo-Gone is my go-to but sometimes it needs a bit of "help".
Thanks,

Re: Removing the Adhesive From Hell
I use a variety of methods and solvents. A very good one for masking tape is to tear up a paper towel and fold (2 layers) into a size a little larger than the tape. Saturate it with WD-40 and go away. Next day, the tape is usually soft enough to come away in one piece. A similar method for removing Sharpie writing uses bleach on the paper towel to lift the ink from the paint. Used it many times, but YMMV.

Re: Replacing missing button cap(s) - HP 339A
We do need to nip this conversation in the bud. While it is tangentially on-topic, it's not likely to be tolerated for long. If I were watching it as a moderator rather than participating in it, I'd be waiting to pounce.
You've misinterpreted the "direction" (for the lack of a better way to articulate it, not enough coffee) of my point. It's not a matter of someone dictating to you what you can and cannot do with your stuff, it's a matter of you making good decisions about what you do and don't do with your stuff.
To illustrate my point: If I just happened to be the owner of the Mona Lisa, I would take great care of it. I don't particularly like the Mona Lisa; I think it's a fairly unattractive painting of a fairly unattractive person and I just don't see the appeal. But I am aware that most of the rest of the world practically worships it, and I would take great care of it for THAT reason. If I really, really needed a dartboard, I could certainly use the Mona Lisa as a dartboard. Of course, because I own it, I can do whatever I damn well please. But would I? Of course not, because (in this context at least) I am not an asshole. This is the difference between "ownership" and "custodianship".
That's the best I can do today to illustrate the point I'm trying to make. The degree of importance of an item to a person or persons is immaterial (Mona Lisa vs. an HP 141T), the logic is the same.
This mailing list serves many purposes for many people who are interested in HP gear for different reasons. One of those purposes is to try to preserve that gear.

HP8330A radiant flux meter service manual anyone?
I found a HP8330A meter plus 8334A detector and they seem to be OK, apart from noisy readings on CAL and measure.
Searching the web for a user / service manual has so far been a dead end, apart from an article in HP Journal 1971-07.
Even a mere circuit diagram would be very helpful. It boils down to a chopped DC nanovoltmeter, but it would be nice to get
it working properly because of the broad wavelength response and direct readout. Cheers, Hans

54615B Agilent Scope Amplitude Low When Measuring 120V AC
From: Bostonman
Date: Sun, 14 Nov 2021 08:02:21 PST
I have an Agilent 54615B scope that works fine, except, the other
day I measured the AC line voltage (119.8V on a meter) and got
318V p-p on both channels.
I used another oscilloscope and confirmed the amplitude to be
approximately 340V p-p.
At low voltages such as the probe calibrator of 5V, the scope
measures correctly.
It has passed on the self calibration, and, from what I see in the
specs, it shouldn't have such a huge error at high voltages.
Does anyone know if this is normal of does something needed
adjusting?
Well...
Assuming a good undistorted sine wave (unlikely but later...)
119.8 x Sqrt(2) = 169.42V Pk.?? (Was the meter a "True RMS" type or
just any-old meter, DMM or moving needle!? Plus what is it's
supposed and/or proven accuracy.)
x 2 = 338.84V pk to pk.??
BUT!?? If the mains waveform is at all distorted (Highly likely)
it is probably "flat topped" (because of the thousands of low
power non corrected rectifier/capacitor input power supplies hung
off the line, not just in your premises.
So you indication of 318V p2p is in the ball park.?? Only some 6%
adrift.?? Not to bad in truth for a mains power reading taken with
two different instruments, without knowing the distortion factor /
harmonic content due to poor power factor loads elsewhere, and how
said instruments perform in the presence of such distortion.

Re: 54615B Agilent Scope Amplitude Low When Measuring 120V AC
The probe is generic, but I tried a newer model Agilent probe I believe. As for the coupling, I believe just DC.
The other scope is my higher end 54831.
I was unaware specialized probes should be used for measuring AC lines directly. What do you suggest?

But, given the current political situation, there are many, many Libs just waiting to pounce on this argument, and take it to the extremes to suit their Lib, anti tech agenda. If we do not watch carefully, all the time, then we wake up in the CHAZ. Well as this very much Lib, but very pro-Tech, I'm willing to admit that there are things in life that I care about, like well-engineered test equipment, and it makes me angry when morons destroy it. It makes me even angrier when they do it to prove how manly they are, exercising THEIR AUTHORI-TAY over it, etc. People are on this list because they like, use, love, are curious about, or whatever, HP test equipment. I think I'm probably not the only one in this 5K-person list that gets angry about crap like this. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Re: Replacing missing button cap(s) - HP 339A
What a fascinatingly stupid discussion. And I will prove it so: Desired, rare, sought after, beloved implies valuable which equals $, money, moolah, cash, cheese or whatever lingo you choose.
?
However I have found the ones who cry the loudest and beat their breast in anguish are the cheapest, stingy-est SOB's on the face of the earth, generally. Not casting aspersions on the folks currently engaged in discussion, as I know you to be fine folks.
?
And there is nothing sacrosanct about test equipment, no matter who makes it. It was designed for an economic life of 5-7 years. The stuff are MERELY tools used to perform a job. And when tools wear out, or are superseded, they are discarded.
?
I have seen literally MOUNTAINS of HP & Tek go to the shredder. Uncle Sam just don't care.
?
And complained about it, have tried to get guys to go in with me to buy the stuff out to save it, move it, store it, but no one with cash, time, energy or SPACE ever steps up.
?
They want to pick it out of the dumpster. Which is fine, god bless you for your luck, but rare.
?
So its no big deal. Really it isnt. We are dinosaurs clinging to our "goodies" which are rapidly becoming not worth the space they take up. My engineering students couldnt care less for these boat anchors. Apartments are small, and costly. And they do not have the attention span to learn how to fix things
?
Take it from someone who still has mountains of the stuff, and realizes that all things eventually "go away".... I just brought back to the school a VERY large pile of TE that was donated, and have realized, while testing some of it, that almost all of it is probably sick or bad, or useless. All while hoping there is enough useful for the labs to have made fetching it (gas and time) worth it.? And there is not enough of me to fix it all.

Re: Replacing missing button cap(s) - HP 339A
Hello Dave,
sorry to step into the fray here. You are an old friend, and I know how you meant it, and in principle I agree with you.
But, given the current political situation, there are many, many Libs just waiting to pounce on this argument, and take it to the extremes to suit their Lib, anti tech agenda. If we do not watch carefully, all the time, then we wake up in the CHAZ.
Or, like in some countries in Western Europe, where an architect can prevent a legal owner from changing a buildings design because, muh art.

If you want to scrap the instrument and turn it into little
metal shavings, you can, and nobody can do a thing about it.
That isn't really a custodial relationship.
I get touchy about this subject because I have seen numerous
cases where people that do not have any stake in some thing,
be it a house, aircraft, computer, test equipment, cars, or
another, attempt to force the owner not to employ that item
in a way that the non-stake holder feels may cause it harm.
They never seem to have the money to buy out the owner, but
always want control, at the owner's expense.

Communism and socialism are based on that very idea.
The belief that personal ownership does not exist, but
rather people only have stewardship of their "belongings",
carries forward to the logical conclusion that people
are not the owners of their bodies and minds.
That condition is known as slavery.

They're not paid to consider the intrinsic value of that to
anybody. It doesn't contribute to how they are judged, which is
the corporate bottom line.
For a scrapper?
What are the pieces worth? What can I get for these useless
cables I've cut off, they're all copper, aren't they? Manuals?
What's the price of used paper per ton? How much gold can I get
