Just to set the record straight, the 8644, 8645 and 8665 were all developed at the same time as part of what we called the Performance Signal Generator family. They share hardware but there are differences between them. The 8643 is an 8644 with a different power supply and without the 140ns frequency discriminator option. The 8664 is an 8665 without the output section to operate above 3 GHz.
The 8645 was designed for fast frequency hopping applications. The 8644 was a general purpose generator covering the same frequency range. The 8665 with its YIG oscillator extended frequency coverage to 4.2GHz (A version) and 6 GHz (B version). All three utilized a single loop fractional N synthesizer with frequency discriminators to enhance phase noise performance.
These generators were designed at the Spokane Division of HP. One other generator followed which was the 8647. It was a low cost generator that used the signal generator hardware developed for the 8920 test set. Around 1992 the RF signal generator charter moved from Spokane to Santa Rosa so Spokane could concentrate on cellular test. The 8648 used some of the 8647 design but the RF hardware was different and was designed in Santa Rosa.
To be complete, the 8640 and 8660 were designed at the Stanford Park division and their production was moved to Spokane when Spokane split off from Stanford Park. The 8642 was designed in Spokane to be a programmable replacement for the 8640. The 8642 was a multi-loop synthesizer design that used fractional N synthesis in a low frequency loop.
The 8662 was designed at Stanford Park and the 8663 was in development when it was transferred to Spokane. These generators had very good close in phase noise performance but were worse than the 8640 or 8642 at higher offsets.

Guys,
The 8664A and the 8643A are from different subfamilies of generators- so while some circuitry is the same or similar - the factories leveraged existing circuits all that they could.
The 8640B ->8645A, possibly even the 8648A are in one subfamily - analog oscillator with lots of digital control. The 8660A -> 8665A are in another subfamily - full digital synthesis and digital control. Check the block diagrams for both series.

I had exactly the same problem on the CRT of my 181A oscilloscope. I
repaired it by putting the delaminated flex cable together with some
2-part epoxy. While the epoxy is curing, it is vitally important to
pinch the cable as thin and as flat as possible, so that it remains
flexible. I held it with two pieces of cardboard, secured in a vice. Hi Joel, Yes it does, thanks for the reply. I'd be interested to know what your ribbon cable looks like. Was it removable at the CRT end, or integrally connected? I can see some very difficult aspects to this repair. If it's delaminating along the whole length then the whole length would need to be reglued, but a perfect seal would only be needed in the gap between the 7.5kV conductor and the others? I am also thinking that slicing the 7.5kV part away from the other two and heatshrinking it along its length would also work. I might even be able to avoid removing the entire CRT this way (it took me a few _hours_ to remove a broken CRT from a 1335A plus I'd be very worried about damaging this one. These CRTs now seem to be unobtainable, period). Never attempted anything like this myself so it is great to hear from someone who has resolved it before! --Toby
I hope this helps !

The 8664 charges the battery when plugged in, at least mine did. I replaced them anyway.

Re: Performance verification on a HP8510C
Hi Job, You are welcome, verification process is basically having VNA to measuring all components in a calibration kit and then compare the obtained S parameter data to the HP factory supplied data (with verification kit) to see how much it is off. I think by measuring the verification kit component and look on the displayed S11, S21 you should already know if your cal kit or system is ok or not. You don’t really need to run the verification program, unless you have other serious need. I strongly suggest you to download full manual in my previous link and read section 8 for more detail. Good luck. ? ? Best regards,?? Steve Cheng? ??????????????? North American EMC Certification Services Inc.

Hi Steve,
Thanks for highlighting the requirements. I guess I was hoping for a more
modern solution. Unfortunately it seems the commercial HTBasic package is the
only option in that sense. At least I have not found indications otherwise. I
better first get hold of the software disks and see if I can figure out what
they do.
Best regards,
Job

Dear All,
The HP8664A is in the same family as the HP8643A, with many modules common.
On my HP8643A, the battery only seems to charge when the generator is switched on, not when in standby.
I, too, had calibration errors when I bought it.
There were two causes:
1. An internal connector that was not properly seated.
2. The battery issue.
These days, I switch it on for a few hours every couple of weeks- that ensures it holds last settings and does not get stuck in the cal. errors problems.
I’m sure the battery could do with replacement- does anyone know where the battery is and what is a suitable replacement type?
Other than this issue, this is my chosen generator for reciprocal mixing measurements, as it has very low amplitude and phase noise for a synthesised generator of that era- I believe it was made for testing aircraft landing systems (ground segment- it weighs so much, an aircraft might struggle to take off, unless it was a B52).
Regards,
Alwyn

Re: Performance verification on a HP8510C
Hi Bill,
I will have the 3.5mm Verification kit and I have a cal kit. So it is up to the software to make sense of the data disk of the Verification kit. I do not believe it is in the controller as there is a 2 disk set (08510-10033) for this purpose. But before I go after it I want to know what I do with it as I do not have a HP9000 system.
So far I understand that to use a NI GPIB-USB dongle with it you need HTBasic ($$) to run it. So maybe it would be better to understand what the data is on the data disk or what the verification software does and replicate it in Python or so.
Best regards,
Job

Re: Performance verification on a HP8510C
I do not believe the verification SW ran natively on the 8510 - if
there is any verification software that does, I have never seen it. There IS diagnostic software that rns natiely. maybe that is what you
are thinking.
