Re: Retrofitting 3.5mm connector from HP 8485A sensor onto an existing HP 8481A sensor - possible?
I think it is likely to work - BUT, the assembly and disassembly will be (at lest) challenging. The thermistors may be similar, and possibly the thermistor board in the cartridge (you need to check

Re: 33210A load waveform over Ethernet
Hi Peter, I don’t have 33210A, but it’s same thing with an 33220A. I used the free Agilent IntuiLink Waveform Editor software. In the File Properties menu, I chose the number of points;

Re: OPT 003 (48-440 Hz compatible) fan (full size "Muffin" type fan) - replacement requirements?
If it is from a 8660, don't be tempted to go with a lower power fan, HP had some reliability problems with early 8660A & 8660B, this lead to them offering a free upgrade to a larger size fan in 1974

Robert, Adrian - thank you both for adding to discussion - this information helps because I also have OPT 003 in old HP 8660 series synthesizer (also very heavy machine) so good to have these

33210A load waveform over Ethernet
Just wondering if anyone has experience loading a one-shot retriggerable waveform over Ethernet into a 33210A arbitrary waveform generator. I'd love to hear the Reader's Digest version of how I can

Re: OPT 003 (48-440 Hz compatible) fan (full size "Muffin" type fan) - replacement requirements?
The difference with the option 003 is that a *DC* fan is fitted rather than the mains (50/60 Hz) AC one in the standard unit. This give you more choice of replacment fan. Take the old one out and see

Re: OPT 003 (48-440 Hz compatible) fan (full size "Muffin" type fan) - replacement requirements?
What is the problem with it? I had a very noisy one of these fans and any 400Hz capable replacement was very expensive. In the end I simply took the old one apart and replaced the two bearings. They

Re: Retrofitting 3.5mm connector from HP 8485A sensor onto an existing HP 8481A sensor - possible?
From experience, the 8481A series does not perform up well beyond 18 GHz. The response drops very quickly towards 19/20 GHz, and at 26.5 GHz, the response difference is more than 3 to 4 dB. The N

A bit of a follow up on this. I think the point about stereo microscopes giving indication of depth is invaluable, and exactly the kind of information one hopes to get on here. But I will say I also
