I restored one of those for someone about 15 years ago and wrote a Windows GUI for it. It needed Intel HEX via RS232. Very cool, but incredibly slow.

Does anyone out here have the original software for the Stag PP28 programmer?
I have one saved from the skip years ago, it has been unused since...

[maginnovision]

My 1082 came in today. Accuracy is better than the display for sure. That number is accurate.

Edit: It's all warmed up now, mostly sits at 0.00000 to -0.00004 so this is actually an outlier.

One more edit, I bought 16 LM309K's. Mostly gold but 2 steel as well. At $4 a piece I figured why not.

Couldn't find any info on it, and it said Fluke, so I obviously had to buy it.
I guess its just a signal generator they built to easily demo their frequency counters.

Sold my old one 1xPA8700@550Mhz gean and bought a new PA-RISC workstation 1xPA8700@750Mhz.
It's what I daily use for everything, so more Mhz makes the difference.

Beautiful 

I'd suggest that you contact Fluke to see if they are willing to provide any information. Guess that trying the phone number in the sticker is out of the question by now. 

Seems that your photos could be a rarity to be found on the web, so... can we expect any "take it apart" in the mean time.
If any intervention was done over the years, some caps are gone by now. But if you intend to restore it, please take some photos before doing anything, just for history record purpose.
Glad you grab that piece of gear.

Just a guess but it does have 'Counter Demo Aid' on the bottom of the Fascia. I would think it is just that made to demonstrate and sell other gear. Occasionally Badged gear turns up as an unknown and some of that was used for internal production and testing.

Always cool to see internal/demo equipment. I also vote for more pics and teardown in its own thread.

A ball point+capacitive touch pen+ruler (1cm/div, 0.5cm/div, 0.33cm/div and 1"/div)+level combo from a sales rep. Pretty good building quality, full anodized aluminum body.

What is the internal cartridge

[tautech]

What is the internal cartridge

I don't know. It seems it's not designed to b refillable.
BTW, while I was trying to open it, I discovered it also has a flat+phillips screw driver set in it.

I'll take it back. It's refillable, with a 2.75" metal refill.

Pics ?

Is it a promo gift from Keysight?

Nice.

So it's ESD safe too?

Though they might look alike, I doubt that the build construction and materials of the Aliexpress pen has any similarity with the Keysight gift pen

It's like Rotring and Redcircle

Looks like a Monteverde Tool Pen.

The ballpoint pen version has got the level, there is also a pencil version that doesn't.

Look more useful than they are, however. At least if you're actually looking for something to write with .

I picked up a HP 5316B Universal counter off of Ebay.  Made an offer.
It comes with an original printed manual.  We'll see how it goes after it gets here.  Check caps and make a OCXO for it.

Bought a HP4440B decade capacitor from eBay, 40pf-1.2uF:



The construction looks very nice:



Double shielded: The outer case and then inside an aluminium box. Works without problems. Accuracy much better than the usual 10% you get from normal capacitors. It was worth the $200, I could already use it to fine-tune a Qi receiver.

They are a nice bit of gear toward a reasonable Calibration Box for some general purpose LCR meters. I stripped and cleaned mine as it had a bit dirtier face than yours here https://www.eevblog.com/forum/testgear/hewlett-packard-4440b-decade-capacitor/msg1376042/#msg1376042

[Jeroen3]

Does this count? I did buy and assemble it...

The Prusa i3 MK3S.

[dirtcooker]

The brand is shown as Hiltand. However, I purchased one and the unit I received appears to be a genuine Kunkin. The unit performs well, the battery capacity function is especially nice and allows setting a low voltage limit, CC and CV work well. CR mode has some strange behavior, I need to test more to see what is going on.

Boy could I have used this Jul, 2014.  I built a L-C meter from scratch but couldn't calibrate it any better than about 5-10% for lack of a standard.
How do you know how accurate it is?  What do you have to compare it with?

I have a HM8018. Some measurements, with the fine-tune knob at 40 pF, measured with my shielded Kelvin probes and 100 Hz measurement frequency:

- 0 pF (plus the fine tune knob and the cable etc.) : 48 pF
- 100 pF: 150 pF
- 900 pF: 951 pF
- 12.3 nF: 12.36 nF
- 765.4 nF: 765.5 nF
- 1.1 uF: 1.100 uF

Looks like it is dead on. I guess the trick is to use high quality capacitors, which doesn't need to be very accurate, but with very good long term stability, and then trim each capacitor with parallel variable capacitors. You can trim each of the bigger capacitors, as shown in the schematic in the manual linked in the article from beanflying. I didn't trim it so far, but maybe the seller did.

[maginnovision]

I got an RV-622A which I can't find any actual data on. Initially I was disappointed with the accuracy because dividing my 7.090462V reference by half resulted in more than half. Then I remembered this DMM is only 10Mohm in 30V range, the Datrons are the Gohm DMM I have for up to 20V. Any ratio that allows me to stay in <= 3V range is just about right on. For this picture I set it to Ratio with the value of the reference(just measured) as the reference voltage. Pretty much perfect but I already feel like I should have just bought a 7 decade kelvin-varley divider. Maybe later when a 720A isn't so expensive especially now that I have a perfectly good divider.
