Re: HP 8595E SA DB-25 RS232 is not functioning.
Hello again Candrian. Sadly I do not know enough about those hardware options, to say for sure.? But if I had to recommend anything, I'd go for the HPIB(GPIB) interface designed for that analyser, if

Re: 5086-7337 *Yig Oscillator issue*
Most of your assumptions are true, but if the end point voltages are not reasonably close you won¡¯t see output at either end. You might find that if you supplied a tuning voltage to the YIG

Re: 5086-7337 *Yig Oscillator issue*
Recently I've resolved the burnt T1 transformer issue on the mainframe. You can see that in my older 8350B post. I think the mainframe is now ok, but the definitive confirmation is try to operate a

Re: HP 312A wave analyser
For that generation of instrument, my first guess would be CdS. These are light-controlled resistors, so photodiodes/phototransistors would not be acceptable subs in most cases. -- Cheers Tom (btw,

HP 312A wave analyser
I have recently acquired an old HP 312A wave analyser, which has been sitting around in a lab with little use. I would like to know about the photo conductor block ( P/N 1990-0009 & 5212-B3H, that

Hi, I just tried the COPY button and I received a bunch of characters on my RealTerm . So it seems you are right Dave maybe option 023 is only for outgoing messages and no option for remote

Re: Looking for a feedthrough capacitor
How much room on the 'other' side from the 90 deg bend? Would something like this: https://uk.farnell.com/oxley/dlt-4700/cap-4700pf/dp/149151 be made to fit with a bit of a spacer under the hexagonal

Re: Looking for a feedthrough capacitor
You probably have to enter it on the german site, I don't know. Its a guy who sells 5 PCM testers for 370 EUR. He bought them for the sole purpose of having parts for his NFAs... cheers Martin

Well, yes, just one instrument for both of us would be fine.... But no, thanks. Cheers....

Re: Looking for a feedthrough capacitor
Hi Harke, item #294954912663 on a well known auction site would probably yield a good stock of these. Not a bargain, unfortunately. cheers Martin

Re: Looking for a feedthrough capacitor
Hello Martin, I immediately recognized this feed-through capacitor. Seems typical for WG as my Rauschpegelsender RS100 has the same. One showed a short and as I considered it as unobtanium, I just

Looking for a feedthrough capacitor
Hi all, I'm looking for a replacement for a shorted feedthrough capacitor for my SNA1 Wandel & Goltermann analyzer. It seems special in that it is very thin on the interiours side, where the bended

Hi again. I pulled a manual from:- https://www.manualslib.com/download/529136/Hp-8590-E-Series.html After a lot of scrolling and reading, sadly, the only references I can see for the RS232 port, is to

Re: HP 8595E SA DB-25 RS232 is not functioning.
Thank your for valuable notes. What I did try yesterday was to clear DTR (PC) <-> CTS(SA) and set RTS (PC) <-> DCD (SA) but I didn't observed the L letter on bottom left but nothing. I'll try the COPY

Correction - to the lines in the message below To get an L, SA CTS must not be asserted, because T will obscure the L. Then SA DCD must be asserted (+). If both CTS and DCD on the SA are asserted,

Re: HP 8595E SA DB-25 RS232 is not functioning.
Ok, getting the T is reassuring. To get an L, SA RTS must not be asserted, because T will obscure the L. Then SA DCD must be asserted (+). If both RTS and DCD on the SA are asserted, i.e. when the pc
