Connector miskeyed?? Off by one?? bad? Any idea what line is shorted?? Resistance with the power supply off but plugged into the backplane? Guesses. Harvey

I have an 8711B where the power supply runs when out of the chassis but when plugged in it keeps trying to start as if there is a short. I have determined that the supply acts this way when the small

These MXA options are ridiculously expensive for a hardware that is included on analyzer. Ing. Patricio A. Greco Taller Aeronáutico de Reparación 1B-349 Organización de Mantenimiento Aeronáutico

Ok, *that* is compelling functionality. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Here's the datasheet for the N9020A? MXA analyser Keysight N9020A Datasheet (testequipmenthq.com) ( https://www.testequipmenthq.com/datasheets/Keysight-N9020A-Datasheet.pdf ) It may be the case that

And hopefully they will stay there, until there's a *real* need to move to something different. It hasn't been a limitation for my work, but see below.

All of the 15-20 year old E4440A PSA analysers are still in use at work despite the ~2 minute boot up time. There's quite a few MXA and PXA analysers at work as well. A fairly decent analyser will

You won't be able to set up the power supplies by themselves, the other rails depend on the -150V rail, which has the voltage reference tube. Pulling the 6AQ5 (V17 in the pdf manual) would be enough

The startup time of the 70900B in my lab is about 9 seconds. This is what happens when something is effectively a solved problem and all that's left to "improve" is the production cost. And, well, of

This is getting a bit silly now. The boot time for the classic Agilent E4440A PSA spectrum analyser is quite long This was the industry standard spectrum analyser since 2001 until the PXA/MXA

Please forgive the off-topic post, but I know of no greater concentration of technical knowledge than this one. I am looking for documentation for some Physik Instrumente piezo nanopositioner

Not me, I know enough to have stayed away from it for my whole career. I'm not a patient man. Ignoring its fragility and instability, many of its problems can be sidestepped by not connecting it to a

And yes, it needs a rather 'stiff' 10 MHz ext ref, I think I feed mine 12 dBm or so (subtract some coax attenuation though) Wilko

I'm looking for the system software for a HP 80000 [2900A]. If anyone has the 3.5" disks but not the equipment to read them, I can copy the LIF disks and archive them for posterity. (My recollection

Does selecting the selftest display 75 000 000 ? Without a reliable 10 MHz clock int or ext the CPU does not run. Essentially nothing works properly. The switch for int/ext has been known to become

True, many Windoze things may be run using wine +....otherwise lets keep it that way as virus writing by the "disruptors" is minimal...let them go after Apple and MS...and lets not forget big brother

That's a pretty laughable statement today Jim. Even my CPAP machine (which is also certified as a hospital ventilator) runs Linux. It was easier to get it through FDA certification than Windows, from

I'm a design engineer. I've held a ham radio license since I was a teenager in the 1980s. I don't think that's relevant to this conversation. You'll find that most people with more than a passing

Thanks David, all precious suggestions. I'll get a light bulb of suitable wattage and start disconnecting the HV section. I am still confused about how to interpret the board connection on valve
