Good morning, I have a 419A Nulling Voltmeter that I just finished replacing all the electrolytic capacitors in. This cleared up my 'after warming up no operation' problem. However, I also had to

Basing my replies on what's available for the 16500 and 165x series: 1) Don't think you'll find schematics, they may have existed only as internal documents never to be released. Tektronix did about

List, You may want to have a look at this link http://alytus.auksa.lt/esr/esr_meter_schematic.pdf I've been thinking of building this one myself. Chuck Lippmeier <rpgroschen@...> wrote:

HI Group, Just wondering if anyone has seen schematics for this series of logic analysers/scopes and if anyone has any info on programming these units. What OS do they run? Can one write programs for

Nice Job! Cheers!........................................................Don C.

I recently got laid off at my job and decidet to go out on my own as RF/Microwave consultant, if anyone has a need for consulting work in this area including microwave T+M contact me

This a very long shot, but if anybody can help me getting a piece of the trigger hybrid for a 54121A. HP part number 1NB7-8130 I recently got a 54120B with the 54121A but they took a the

9000 calculators are not all that big, most sweepers like the 8350 and wiltron boxes and even the old 8620 has GPIB (on the 8620 as option) the software requires certain equipment but since its HP

Hi, Those interested on a low-cost alternative to evaluate ESR, without the trouble of building a dedicated instrument, could find this page an interesting reading:

In reply to your comment below: The test voltage across the leads is under 100 mv and capacitors do NOT need to be out of the circuit to test.... ac power does not in any compromise the functionality

The XR 2206 data sheet is here: http://pdf1.alldatasheet.com/datasheet-pdf/view/80496/EXAR/XR2206.html This device is available at Jameco for $3.59 and has a frequency capability to 1 mHz with high

Well, it's a big deal if I don't have room for a 9000-series calculat

Hmm, I wouldn't say that, when you can get a whole parts unit minus the CRT and cables for $810 (e.g. item 140172731962). What are the requirements to calibrate a 70000 outfit, by the way? A

I'm glad to hear I'm wrong about the schematic availability! If I don't see schematics from any of the usual manuals vendors, or from Manuals Plus, and if they're not available at Agilent, I assume

I have been told by a SA person at Agilent that the 70900A is no longer supported or even repairable. If you're putting a system together from various pieces, you should try to find a

Recently I had to troubleshoot a loop lock-up failure in a HP 8662A. The problem turned out to be a defective tantalum electrolytic, which was obvious when measuring its ESR. The ESR tester I used is
