Hello! Some of you will probably remember my query for an IC in the display section of my HP-8558B. Well, thanks to the help of several List members, I knew...
I've found these items for sale and the owner who bought it at a sale claims that ii was a lab system that works together. Prior to this I was lead to believe...
The 8444 was designed to work with the 8554. The 8558 is from the next generation of spec-an's, so I have no particular belief that it's compatible. I hope...
Hello! I have an small jewel and it is no less than an advertising catalog from HP, published 1/76 (publication is HP# 5952-9212), when both HP141T series and...
The 8554 has a fixed frequency third LO output at 500 MHz. The standard 8444 works with it FB and uses that third LO output. Option 059 8444 has a 500 MHz...
Hi Gang, I'm looking for a replacement CRT front cover for a HP 5371A. It works just fine without it but I'd like to find one. HP PN 05371-80004 MFG: H-P ...
[Jose Gavila and Dave Brown pummel me with facts] Thank you, gentlemen! Jose, is there a scan anywhere of either of those documents? Sounds like something...
Hello Dave, ... I don't know... what I have are originals and in mint condition; I found them inside an HP8558B manual I bought some years ago (just in case...
hi i need operating system for hp54540a best regards hp_agilent_equipment Moderator <hp_agilent_equipment-owner@yahoogroups.com> a écrit : Hello, Welcome to...
I have an HP 140T/8555A/8552A. When I added an 8444A-059 I made up a cable to pipe the 500-MHz 8555A LO from the 140T aux connector to the 8444A. I thought...
Brian thanks for the pointer. I wonder if was a level problem caused by loading? Maybe someone knows. tnx Hank ... From: "Brian Beezley" <bb@...> To:...
... loading? I don't think so, Hank. Both outputs are intended to drive the 8444A input. And there really wasn't a problem with either source. The 8444A was...
That's a possibility. Another possibility is feedthrough of the generated tracking signal back into the analyzer via the new 500 MHz path. Without a better...
hi i need operating system disk for 54540a for X-Y operation best regards Dave Brown <tractorb@...> a écrit : For a free running 500 MHz oscillator,...
Hi, I wonder if anyone has the manual for the HP410 voltmeter that has the later model amplifier board fitted (LM308 op-amp and dual J-FET). I've downloaded...
Hello Don, Joe and the Group, a friend gave me a 410C with the photochopper. When I first used this instrument my hand kept looking for the "ZERO" knob that...
... I don't have a 410C, but peering at the schematic, it is not dissimilar to the 3400A - nuvistors, photochoppers etc (although later ones subsituted an FET...
My 410C is the model with the OPAMP, and I used to have another that was the photochopper model, and both stayed rock solid on zero. There is no need for...
Hi John, I`ve come to the conclusion that the 410C isn`t meant to zero exactly, because of the way the feedback is organised. I don`t think that not being able...
. ... surprise ... Yes I agree, tweaking the rear panel adjustment shouldn't be a frequent operation if the instrument is working correctly. Just interested to...
... Hello Chuck, thanks for the reply, who knows how many people have owned the instruments prior to me and what has been sprayed on the switches. All sorts of...
... Hi John, The AC probe, is one of the best and worst features of the 410 family of meters. It is nice that it is reasonably accurate from about 25Hz...
Hi, Just one more thing regarding the 410C using an op-amp and two input FETs : If the warmup drift annoys you, it is probably possible [Sacrelige to the...
Hi, Has anybody made use of an HP3712A IF/BB receiver for something other than its intended purpose. They frequently appear on eBay in the UK but usually don't...
