Re: [time-nuts] HP 5342A (18 GHz) vs 5352B (40 GHz) frequency counters

I've got a few of the 5342s their weak point is the sampler. It can be fixed if you have a die bonder all of mine have the option 1 which is either a 10544 or 10811 depending on vintage The 535x series are nice counters I've got a couple. The bad thing is parts are even less available

I am looking for a microwave frequency counter and won an auction for an 18 GHz 5342A with the GPIB option today @ £200 (GBP). I have just paid for that. I also have the chance to get a 5352B 40 GHz counter for £500. That has GPIB as standard. In the short/medium term I don't see much use for a

David a free opinion and thats about what its worth. The 5342 counter was a good counter but very old now. I used to use the 5342s for satellite work and always wanted one for home. But given its age circa 1980 I believe, maybe it works or not at all frequencies. I would simply go with the 5352b

Dr. Kirby, The 5242A Option 001 (high stability) used a 10544 oscillator, which. IIRC, is electrically interchangeable with the 10811. The 5352B Option 010 (high stability) uses the 10811 oscillator. Cheers, Dave M Dr. David Kirkby (Kirkby Microwave Ltd) wrote: I am looking for a microwave

I have one of the source locking EIP, which works up to 90GHz, but used only for 60,xx GHz only, they are sometimes relative inexpensive available on e-bay, see here:

The manual stated HP5342A have a option 001, it's a HP10544 OCXO with PC card connector(A24), but when I opened my HP5342A, there is very limited space, I doubt it's whether can contain a big 10544 OCXO in there. So I always use a external 10MHz to feed my counter. Hui Zhang At
