I realized a couple of hours after sending the initial post, that I was incorrect with associating Calibration with the Port Extensions. Here is, I hope a better explanation of what I am trying to do.

Hello, I have an HP 382 that I use to control an HP 3048A system. Currently, I have a disk image containing an HP BASIC 6.3 installation that I serve to the 382 with HPDrive. This works, but there are

I used a little hook like the ones you can buy at a hardware store and glued it into a small plastic rod Sent: Friday, May 27, 2022 1:29 PM To: [email protected] Subject: Re:

Most of my (many) items of HP gear arrived in the UK from the USA so I've met this issue a few times, what I do is: Check that nothing is bent/twisted, take a pair of thin(ish) nosed pliers - with

Tom, Give it a tug - they’re in there pretty tight! I just pulled one to be sure and unless someone has damaged something it should pull straight out. Steve K.

there is small hole on card use a hook and pull, swinging the card from side to side There is no locking except fuse lever

As I recall, there should be a little hole in the small PC Board. Hook it with a Small Screwdriver or anything else you can hook it with, and pull. Regards Bill Lauchlan Sent: Friday, May 27, 2022

Hi folks, mayby I'm stupid, but I need guidance. I want to make sure my HP85101 is set for 220V before connecting it to mains and powering it up. The line module seems pretty much standard across the

Hi George, This is not an issue with the loads being disconnected. When the overvoltage condition exists, HP advice is to bypass the safety shutdown and measure the voltages. With the normal loads in

I used this one for a similar job, worked fine, didn't need to modify the matching networks, https://www.digikey.ca/en/products/detail/macom-technology-solutions/XF1001-SC-0G00/5872554 You won't get

Hi Dmitry Whilst I share your concerns may I say that the HP fault finding guidance is based around having a set of their 8622A or 8623A PCB card extenders available. Under most circumstances using

I replace the 75 ohm resistors that are in series with the output connectors with 50 ohm. The Inputs on the amps that I convert are high impedance, with loop through so I can easily configure a unit

Dmitry, It always puzzled me that the manual advised you to bypass the over-voltage protection shutdown in the situation of a potentially damaging over-voltage condition. Seems to me that is only

Hello, During a recent repair my 8662A went into shutdown due to the high input voltage at the linear regulator (A7A1) input. Service sheet 56 directs one to ground the collector of A7A1Q16 and then

Hi Stephen, do you still have the 5265A for sale? im in Australia, thanks Ben

Yes 8478B is a transfer power standard for 7mm connectors . It’s very stable , the matching is not the best but with a good VNA are used as transfer standard on most national lab. The efficiency are

If it was used in a standards lab it more than likely has option H01 which guarantees a VSWR < 1.05 at 50MHz , usually either the 8478B-H01 or 478A-H75 or H76 are used for the power level accuracy

This one came from an auction at McDonnell Douglas plant in St. Louis - It was in their standards lab - a long time ago. AFIK the "B" version is the only one available from HP Cheers! Quoting Lothar
