Ah ha, OK I get it, I guess no reading comprehension score for me that day :) I gues it's still a fair enough deal. I wish I could get a good deal on two 8640Bs, then I could keep one, send you

have you ever considered a 5345A ? they are cheap, and they go to 500MHz The marker does not really say anything, most of the time markers are blanked in on the sweep trace not on the RF level,

It better not :) You want to get your epoxy gears out of the RTV mold, right? Cheers, Kuba

Anyone have a schematic for the HP 6220B power supply? Mine's working, but the meter is off. It even reads negative at very low voltages. I've compensated somewhat with the mechanical meter zero

I don't have the test equipment you outlined. My counter is a HP-5245L and limited to 50 MHz. I have been looking for additional plug-ins to extend its range but at the moment I don't have any. My

I have for sale most of the parts from a 8443A. Email me off list if I can help although postage from France may be expensive. I'm looking for a second-hand 08443-60009 inter-connect cable. Steve

youre right john they are good so are the BP series, what you want to stay clear off in the tek camp are the 278x or 279x series, they require special calibration and service software and are a b to

I have some problems with my 8443A and need help locating the issues. The nixie tube display shows all 0. I believe the tracking generator is still working because the marker is on the screen of the

Just to clarify- The 3575 is broadband and requires no special source -or any other LOs - just a test frequency source that covers the range of interest-obviously a swept source would be more useful

I may be thrown off the hp_agilent list for suggesting it, but in addition to Lothar's good advice, you might also look at the Tek 492AP/494P/494AP models. They are inexpensive, portable, and

Does anyone have a working A5 module for a 8433A tracking generator for sale? David KC2JD/4
