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 because all the magic happened on a hybrid circuit which is NLA from keysight and was around $1800 when it was. As to the comment on GPIB it's very popular still as it's a universal interface with a defined interface which is vendor independent and every piece of gear we've bought recently has included it as a standard option. Yes instruments are coming with Ethernet but that's mainly for remote front panel operation. It's useful when you can send a field tech with an instrument who's a local in country have them connect and then you can drive from the comfort of your office and transfer results for analysis But for data collection and production LabView and GPIB still rule the roost.

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

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: http://www.ebay.com/itm/EIP-578-MICROWAVE-FREQUENCY-COUNTER-10Hz-TO-90GHz-INCL-SENSOR-/111503803566?pt=LH_DefaultDomain_0hash=item19f62504ae 73 Alex On 11/21/2014 2:29 PM, paul swed wrote: David a free opinion and thats about what its worth.

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