There were people on here recently looking for donations for the cost of scanning a bunch of manuals and making PDFs out if them. I would have kicked in a few bucks but I do not have a credit card, so

i find myself with a Duraprobe 123 100 mHz probe, which is very nice but doesn't say tektronix on it anywhere. It has H and L adjustments which i assume are intended to get rid of the spikes using the

Hi Harvey, I think you (and Dave before) forget here that the supplies are protected by foldback current limiting. In case of a nearly dead short the current will be much smaller than in normal

Thanks everyone I just must have missed it or typed it in wrong

This one? https://groups.yahoo.com/neo/groups/hp_agilent_equipment/info

Does anybody know the fate of the Yahoo Agilent keysight HP group ? I can't seem to find it anymore

You'll find that plug and play is a good thing. In old tube amps, you could removed the individual tubes (which generally fail with low emission), to make sure that the tubes are not shorted (that's

Not to discount the possibility of a short on +15v, there are other possibilities that may be easier to check out. First, are the rectified un-regulated voltages present and sufficient for the

Hi Gudjon, Certainly interesting! At present my CSA803 is the only equipment with a serial interface and I don't have plugins yet. So testing those Python scripts has to wait. (And I'm not yet

maybe this will help you - I just fixed (sort of) a 465 that was dead. it was dead because the filter cap (the big huge filter cap) on the +5V supply was a dead short, and a prior person had removed

Hi Albert I connect to my CSA803 with an FTDI USB to Serial converter that I soldered a DB-25 connector to. I have rewritten the example programs from the programmers manual to Python and tested on

Harvey, Thanks for your reply. I referred to the manual suggested here by other members, 465 Late, as my sn is the later model. On pg 215 and for the next several pages it explains (to someone with

Look for shorts on the +15 line to ground. I believe that others have said that the reference for other supplies (say +5, and -8) depend on the 15 volts being up and running. Not sure about the +55,

looking at the first trace, it seems as if the B timebase is not triggering properly. You might try A only, and then B only (if you can). From the second trace, it looks as if B is not triggering

Hi all, I made some measurements today of voltages in the LV test point area. The following are results measured with Fluke 189. Tp1536 [+55] reads46.9 Tp1548 [+15] reads 0 Tp1558 [+5] reads 0.6

Thank you all for suggestions - it worked! Indeed, after rotating both the outside (A) and the inside (B) timebase knobs a few times, and cranking up the intensity control, I did get something that
