Re: E5052A Power On Test (3.3V Bus Supply)
Hi, Jeremy. Let me take a look around the labs here at Raytheon. Might be an E5052A or two that I could fire up. Give me a couple hours. Jim Ford Laguna Hills, California, USA

HP 8660B/86602B developed output stability problem, getting-started suggestion(s) request
My HP 8660B/86602B (owned since 1995 - I've owned it longer than it's initial life in industry, I believe) failed to produce a stable output signal when powered up a few days ago (it has worked

E5052A Power On Test (3.3V Bus Supply)
I wonder if anyone here has experience or access to an Agilent E5052A signal source analyser? Mine is about 20 years old and is recently showing signs of unreliability. The main symptom is an

Re: Accurately measuring 1000pF and 100pF capacitors, to calibrate 4276A?
I use a Boonton 76-3A precision decade capacitor for my calibration checks. I originally picked it up for calibration of an old Boonton 72BD meter (0.001 to 2000 pF capacitance range) but it now also

Re: Accurately measuring 1000pF and 100pF capacitors, to calibrate 4276A?
If you need accurate measurements, I do have an Andeen-Hagerling 2500E which can measure C @1kHz to better than 5ppm and 8 digits resolution even at 10pF. I rarely get it calibrated but its still the

Hi Jinxie, Thank you very much for replying. I am currently in the process of attempting the upgrades: I did receive some feedback on the subject - I just need to ensure that I take the time to

Re: Accurately measuring 1000pF and 100pF capacitors, to calibrate 4276A?
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

Re: 8753C VNA option upgrade
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

Re: 8753C VNA option upgrade
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,

Re: Accurately measuring 1000pF and 100pF capacitors, to calibrate 4276A?
Yep, I'm in Japan, so shipping is a consideration.. I don't have access to any standards here, besides what might pop up on Yahoo Auctions or the like.

Re: Accurately measuring 1000pF and 100pF capacitors, to calibrate 4276A?
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.

Re: Accurately measuring 1000pF and 100pF capacitors, to calibrate 4276A?
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
