The Fluke/Philips PM6654C is actually a very nice counter. Both of mine have the high stability timebase. Here's a photo of the counter and some of its friends.
This pendulum is looking very similar to
my Fluke PM6681:
Oculus....your PM inbox is full, tried sending you this msg:
"My package to you seems to have dropped into a black hole. Last scan was yesterday in Memphis, TN with a delivery date of today which seemed like a bunch of BS considering it's last location.
But now, no delivery date and recent scan.

Hmmm. I've had USPS packages show up out of the blue way faster than I expected...will let you know if I get it. I deleted some old messages.
Looks like that I have a sweet spot for R&S PSU
There is another one on the way to me, a NGT 20:
It will fit nicely with my NGB 70/5 and NGB 32/10 (once this is repaired)

No argument from me. It oozes "engineer built" and not "marketing driven". More like some engineers having a coffee in Eindhoven going "oeeehh! Let's add this too".
Anyways, broken unit is going to the Captain. The other one is still on the Bay.
They share equal ancestry.
Made originally in Sweden: Philips Scientific.
OCXO's have a long history which started with the PM660x series.

No, no, no. It's the other way round. Your Fluke PM6681 is looking very similar to my Pendulum CNT-81 !
That was mostly aimed at Robert, I guess. I'm not trying to push it down your throat. I've dangled it in front of you, if you don't bite I'm not gonna chase you
Not sure why you think the reason it's not being bought is the heritage. I agree that's a big reason people don't buy stuff, but this *is* an HP machine
My bad, I was biased by the two Anritsu.
Quick update regarding the R&S NGB 32/10:
Today I pulled out the power module and checked the semiconductors. All good, except for D203. This one should be a 1N4006 but for some reason I've found a GI826
I measured the Uf and found a value of around 0.25V, reverse was okay. Checked the datasheet and found that the Uf is starting at around 0.6V (as usual for a silicone semiconductor) and 1.05V@5A. I removed the GI826 and replaced it with a 1N5408 which is imo the much better replacement for a 1N4006.
I will put it together tomorrow and see, if the fuses will blow again. Will also check the capacitors but I need to order the replacements.
Pictures will follow.
Anyway, bed time....
Time zones and work delaying responses :-(
The biggest problem with the 8922x is that - it's BIG. and while the SA works I would not call it full featured or high accuracy. Only 10MHz to 1015MHz, fixed span/bandwidth, very limited maximum span (4MHz, 10MHz overrange) <70dB dynamic range, 2.5dB accuracy etc). The signal generator is CW only too. Yours is an S so not even FM demodulation. Better than nothing, but a R&S CRTU will give a full featured SA to 2.7GHz (same 10MHz lower limit), colour display, full function signal generator (100kHz to 2.7GHz) 50W input capability and power meter in a smaller, lighter box for a similar price.
Which boat anchor? The one Tony linked to or this one ->
If you're talking about mine, the TL;DR is that it listed for 600€. This included eBay and Paypal, so outside eBay 525€ through a bank transfer. 500€ round would be OK for me. Still includes 21% belgian VAT so if you are VAT registered ex VAT price is 425.
if i knew about the 425,- .. i would not have bought the Ansitsu but this HP one for sure... if that helps you to make a choice...it has a TG!
Err no, the 8922x does not have a tracking generator. It has a CW signal generator. The pseudo tracking generator Scalar network analyser software for the similar vintage 8924C (and 8920B) does not work on the 8922x as is. You might be able to write your own though.

At least Fluke updated their industrial design when they aligned with Philips
(This was before I repainted the case. The blue helped but not much)
The Fluke 7260A is just plain UGLY and no matter how well it worked, I wouldn't own one. Plus they wouldn't stack well which is a requirement of mine. . One old Fluke counter I always liked was the 1953A.
it is ok to think "what an ugly baby".
but you don't say it out loud when the proud mom is standing right there!
edit full disclosure.......i DID own a 7260a.
edit 2 further disclosure.......i sent it to med. only because it was just begging to be blue.

What, you get sleep at night??

Ah, it's actually less wide, less high and slightly deeper than a CMU200/CRTU
.. and while the SA works I would not call it full featured or high accuracy. Only 10MHz to 1015MHz, fixed span/bandwidth, very limited maximum span (4MHz, 10MHz overrange) <70dB dynamic range, 2.5dB accuracy etc). The signal generator is CW only too. Yours is an S so not even FM demodulation.
Granted. Still makes sense if you don't want to spend too much and are looking for a single instrument to cover a lot of bases.

No argument there. Even though there's a marginal added value in some of the audio features.
EDIT: it doesn't have an HP sticker though. That seems to matter a lot to a lot of people.
Update on the 4265 stack. Recapped a PSU of a unit that doesn't have a trace. Racapped about 90%, couldn't find the small caps so went with it. No change. Then took that PSU to another unit that mostly works but has a jittery readout. When opening up that machine, it was obvious someone already worked on this machine. Fan was replaced by a regular axial fan. Some caps have already been replaced.
This part of the board has clearly seen heat. In addition, the diodes are clearly corroded. Looks like a previous owner has already replaced the offending caps (didn't bother to get them flush with PCB though).
He also replaced some RIFAs but he didn't bother with the ones under the shield.
Other side of the board. Left upper corner has been hot, clearly. At the bottom its clear RIFAs have been replaced. Anyhow, plugging in my recapped board
The red and black caps are new, the blue ones original (can't find the Farnell envelope
).
The readout is actually no longer jittery, just dim. Works fine otherwise. Unfortunately, the trace cuts out for a fraction of a second from time to time when you leave it running. So close, yet so far away
