Just purchased HP 3586B--EBAY
I waiting to get it, I 'm pretty excited, but also concerned it will need repair. In the listing I note is the display has error code of CE-1. The manual says, "Operator error, Attempt made to

Re: Frequency calibration?
You need to investigate, and measure Allen Variance, a better indication of the quality of an oscillator. What you will most likely find is the GPS disciplined oscillator, though very good in terms

Re: Frequency calibration?
I liked the story about the man with 3 watches. This is what measurement is all about, making a conclusion of the data that you have. The measurements give you an indication of the precision you have

"Not very expensive" as in "compared to buying a particle accelerator" ? ;)

Re: Some HP 8341A questions
Hi, I was able to remove theYTO from the instrument and test it with the aid of a spectrum analyzer and a few power supplies. Mine needs +20V, -10V, and

Re: Frequency calibration?
We need extreme freq stability for our master freq reference for a particle accelerator that is 770 meters long. The original 46 year old oscillator was first a HP107BR special that was at 6.289xxxx

Re: Frequency calibration?
Thanks to all that responded. I am playing with a receiver for Navtex. Problem there is that the nearest station only transmits for 10 minutes (max) every four hours so that makes tuning the receiver

Re: RF Voltmeter?
It's similar to the HP 3400A and the Ballantine 323. The HP 3403C is a true thermal RMS meter, with 100MHz bandwidth.

Re: RF Voltmeter?
The Boonton cables start to have high resistance in the shields, allowing signal ingress ion. The Boonton 91 is a tube model (The only schematic I have is for the 91CA). It has a 50K balance pot

Re: RF Voltmeter?
I have wanted an rf millivoltmeter for some time.? I was using my HP410B which is fine except it won't measure down to the millivolts. Then I realized that my HP54542A oscilloscope has great

Re: RF Voltmeter?
Apples and Oranges. The Boonton 92 is a specialized RF Millivoltmeter. The HP 410 is a general-purpose VTVM whose AC probe works at UHF. “Not quite as sensitive” – yeah, by three orders of

Re: RF Voltmeter?
Michael, I think you are right. From the spec, the Boonton 92 seems has better sensitivity than HP410C, I don't have neither Boonton 92 nor HP410C so I can't comment on which one is actually

Re: RF Voltmeter?
The Boonton 93 is a True RMS Voltmeter, usable to 20 MHz. Maybe he meant the model 92?
By Michael A. Terrell · #86164 ·
Re: RF Voltmeter?
Is Boonton 93 more like HP3400, HP3403?

Re: HP AN/USM 281A Oscilliscope needs repair (San Antonio TX)
Ok, I re-read your original post. Thank you for your patience. I used the calibrator sockets on the left side of the screen with 1 piece of wire in the negative and 1 piece of wire in the 10v socket

Ok. If I can find any of my 32MB ones, I will try it and let you (and the list) know if it will recognize additional memory. -Dave [hp_agilent_equipment] wrote:
