A General Radio 1422D dual range variable would meet the specification. Needs the calbration chart though. The earlier 722D would be OK if calibrated and used at same temperature. Not many units neet

Hello Group,I un-soldered the EEPROM from my HP8753C and went in and modified the necessary bits and I was able to enable options, 002, 006, and 010. I soldered in a IC socket and copied the original

Here’s the deal: HP (and later Agilent) locked these options behind firmware codes tied to the instrument’s serial number. Back in the day, you’d buy the upgrade, call up HP with your serial,

Jinxie, do you happen have keyword for unlocking HP 8753E? Bill? W7AAZ

Is this what you need? Model Number: HP 8753C Serial Number: 3317UO1709 To add : 002, Harmonic Analysis 010, Time Domain Analysis (Std on 8702D), enter the keyword: 3 H T 6 U K Z Z Y 2 M M Note:

Hi. Glad to join this group. I have a HP54502A in fairly good condition I want to fix for my workbench. It fails on A/D test (pass D/A and rest) on CHANNEL 2 only. I have no schematics, just the SM,

Yes, besides the variable 722D, there are fixed caps also. Those can weigh just 8 oz and 4 inches long so more shippable to Nippon.

Yes GR used polystyrene for cap standards. Can you borrow some GR gear to use as a reference to put a good value number on some stable caps to use in your lab? If not I have an extra GR 722D that

Capacitance standards from General Radio are readily available at places like eBay. Barry - N4BUQ

I've recently been tweaking my 4276A LCZ meter, and I am now at the point of needing 100pF and 1000pF capacitor standards. All the rest of the things are easy, I can measure resistors etc to

It happens! I'm okay with that, especially since they were a high chance they were defective anyway. I'll update soon, at least for the supplies and clock.

Hi All, Today (22 Feb) had access to the HP 8670B unit that started this conversation. I've attached three internal photos with close-up of any identifying information I could see. Did some RF
