Hi, I am trying to locate a set of manuals for my 8505A network analyzer system. I need: HP8505A Opt 5,7 (3 volume set) HP8501A HP8503A Opt 1 I have found some...
Anyone know if a CLIP (component level information packet) was ever issued for the E4411 (ESA-L1500A)? In particular I'm ultimately looking for schematics or...
Hello, I've got a shorted transistor in the RF assy of an E4411A spectrum analyzer. I'm looking for the mfg/mfg pn. It is a surface mount device, 4 gullwing...
I finally got an HP rack from a flea market! It's the newer kind, that does not use unistrut. It came with some rack slides. The slides won't fit any of my...
I believe the part I am looking for to fix my E4411A is a HP (Agilent) ATF-21186 GaAs FET. The '21186 went out of production in 2001, so I'm trying to hunt...
Hi: I'm trying to reverse engineer an RT-1444 which is the remote control add on for the PRC-104 H.F. radio. It uses a 40 pin microprocessor that I thought was...
HI all, have just joined this groupin the hope that someone may be able to help with problems with my HP5245L. I have replaced all of the electrolytic caps....
... Don, it seems that you might have more than one problem going here. I can't address the others but realized that 50 Hz was your line freq. ("Furphy" was...
I am looking to do some interfacing to the 50-pin connector on the back of a (non-GPIB-compatible) HP 8620C. This looks very much like an old-school SCSI...
The connector on the back of the 8620A is a 18 pair connector that is the same as the one used on the centronics printer cable. The connector on the back of...
Thanks for the confirmation on the physical connector type, guys. I'll go ahead and buy some SCSI interconnects. I am hoping to come up with a PC interface to...
It would be far cheaper to look for some old telephone connectors. There are probably dozens of scrap cables and connectors laying on the ceiling tiles of the...
I'm going to be using this beast for event counting. Would be interested in operation instructions, or tips. Prefer, naturally, a manual - paper, electronic,...
Good morning, I recently bought three HP power supplies, the 6263B and the 6267B and all experiencing the same problem. I do not get any voltage out of them; I...
Rick, Is is possible that these power supplies use remote sensing? If so, you need to connect the output terminals to the sense terminals. If these are not ...
Rick, I am not familiar with these particular supplies, but I have found that with the HP/Harrison supplies (such as the 6200, 6286, ...) there is a serious...
Gentlemen, I just received a 355C attenuator I won on ebay. When put to the test the attenuation is all over the place. Traced the faults to two of the micro...
Hi group: I was lucky enough (?) to obtain a pile of HP 8153A lightwave multimeters in a pile of other equipment -- but no plugins. They do not give any...
Hi All, I just purchased a 54200A scope and have figured out how to generally work the scope but I'm sure that if I don't get a manual I may be missing some...
Bob-- I had one of those scopes. Finding a manual was really tough--I finally tracked one down (xeroxed) from an outfit in Italy that handles manuals. But it...
Bob They seem to be hard to find-at a reasonable price- I think manualsplus have one listed but at 70 dollars for a copy (more for an original) it's a bit...
Thomas, I found a original manual on ebay for $45. BTW, I have a NI GPIB card somewhere, I may give your 54200A utility a try. Regards, Bob ... finally ... the...
Dave, One caution on the manuals for the 54XXX scopes. The service manuals do not have any schematics in them and the instruments have a lot of custom IC's in ...
Sam Tks for the info re Dave Miller. Comments re possible issues with the 54200A noted. For some time the scope was powering on OK but failing POST. Still ...
