I'm curious about this coax aspect if it's on the 3 leads - not the RF.? As far as I recall, those 3 are just single wires, no coaxial content.? DCA/DCV/OHMS/COM - all single wire.? Only the AC

Looks like I need to make a homebrew power supply, considering the cheapest replacement power supply is 250 dollars on eBay. Is the power supply frequency synchronization pin basically useless? The

Looking for a p/n 1251-0135 card edge connector in new or serviceable condition. Please contact me off-list if available: whitreeve@... Thanks -- Whitham D. Reeve Anchorage, Alaska USA ---

Try audio cable. Many musicians have gone to computer based mixers and have plenty to spare. Probably cheap on ebay also. It's super flexible.

Hello to the group. I have several operational 5360s and they are reliable. But when they break it can be a heck of a job to figure out. Thats because they truly were (I believe) the first computing

Thanks all,? my only interest is in the test leads, not the RF probe. I'll just focus on finding a suitably sized and flexible coax to fit, as it does not seem impedance is a concern here.? Was

The probe that comes with is? 11036A AC Probe (to measure AC from a few 10 of Hz to around 1 GHz?)... but with not very good accuracy at the low and at high end frequencies.... at the 'sweet' spot it

At 500mV and up, the 410C's input impedance is 100M. Barry - N4BUQ

I used to have two; both worked partially. The counter was nothing special but, connected as it was to what amounted to a 9100 programmable calculator, it could do impressive work. My two 5360s had

So I ordered some N28F010 150 Intel Flash Memory IC's from Ebay and will be attempting to replace the 1st Flash IC to see if this solves the issue. I'm assuming that the error is indicating the memory

I got one of these from a group member in the SF Bay Area years ago.? It needed a little cleaning, but worked perfectly.? However, the last time I powered it up, I noticed it wasn't behaving

AFAIR, 410c has input impedance is 1 or 2 pf, at 10 Mohm.

I don't know if this helps, but it's always a good idea to check the health of all the 100k ohm and 150k ohm 1206 packaged SMD resistors on the little plug in fan controller board if you have an

David, I found one at Apex Electronics (a surplus place in California) some years ago, and eventually found a manual as well. ?I've yet to attack it, though, and have also spent years on the lookout

That shows operating system A.03.01. The last version is (I think) A.04.01 and if you use the firmware updater it will update the OS as well as firmware if that box is checked. Not something for you

I have one, as does a local partner-in-crime, both not (yet) working. They're supposed to be pretty amazing counters in many ways, but one of HP's more complex and ambitious designs. They're very

I got the board to successfully boot on the bench. (Just the processor board, not the rest of the instrument). With my benchtop setup, I couldn't get the device to boot, but after shortening the

What happened to the 5360A counters? Not seen any for sale in the UK for years, I was warned they are very unreliable, but this doesn't put me off adding one to my collection. David

Some pictures for reference (not for sale), grounded shell versions from both Switchcraft & Tower, the bagged one is ungrounded one from Tower. I've seen them broken from being shipped with the cord
