It probably isn't up to the quality of HP/Agilent gear, but I have a Leader LCR-0745 that works for me. It doesn't have BNC connections on the front, but I am...
Manual contributors: It has been brought to my attention that a recently uploaded manual on my web site was a "cleaned up" copy of an Artek Media scan. I will...
Can anyone point me to a copy of the hp1742A service manual on the web, please ? I have one that used to go dead after a few hours on, but now doesn't start at...
I have a 8640B on the bench with a bad 44.6 volt regulator and I'm wondering what I can use as a sub for Q3 (one of the power transistors on the back panel...
I don't have a current favorite, but scan through page 1240 of the latest Digikey catalog where it shows NPN TO3 transistors by ON Semiconductor, and you will...
Darn , I used to have the cro and the full service manual, sold the whole thing some 10 years ago - damn good cro though, have settled on a pair of 1631's...
Yeah, mine's got the "Time interval multimeter" (ha! they mean 'delay offset voltage measuring mutimeter'!). Actually, that's why I got it - it was sitting at...
290278960138 on ebay is at 8 hours to go and 15 dollars, i dont know the piece of equipment you hqve my self, but it looks like one of the boards has some to-3...
actually, the guy says: "have a Lot of 3 Agilent / Hewlett Packard Model 8640B RF Signal Generator Boards up for bid. They include the: 08640-60049, (Reverse...
I saw Lothar's post yesterday, and although its not a precision instrument, in the sense of HP etc, I do have kits available from my website for an engineered...
Hi George, Before you power it back up with a new transistor check that the supply rail is not shorted. I purchased a dead 8640B just a year ago. Two of the...
... I have a Genrad (General Radio) 1657 that works well. It doesn't go to 50MHz, only 120Hz, but there are other members of the Genrad 165X/168X/169X LCR...
This thread has stirred up some useful stuff; it really made me wonder if my sources are up to par. I used the direct comparison method contributed eatlier; 3...
The IFR communications test sets I've looked at have poor phase noise compared with an HP8640B or, for that matter, even an 8657A. I have some data on a few...
I've read the instruction book several times, either I keep missing this or its not there or I am too dumb. On the capacitance dial there is a red scale which...
If you set the frequency to a prescribed value, you can measure inductance directly off of that red scale. There should be a table with frequencies, and...
Armed with Internet info and pertinent manual pages copied I got busy earlier today. The PS was fine, display worked but the output was down about 45dB. The...
what do you expect from IFR AKA MARCONI ! ________________________________ From: Pete <peterawson@...> To: hp_agilent_equipment@yahoogroups.com Sent:...
... instrument, in the sense of HP etc, I do have kits available from my website for an engineered version of the VK3BHR LC meter. It is a very good little...
All, I recently fixed an 8562A with a problem in the CRT HV module (A6, pn 5062-7089). The problem manifested as a lack of the 110v supply to the Video driver...
