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,

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

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

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....

That item doesn't show up as anything. What was it? -- Paul Amaranth, GCIH | Manchester MI, USA Aurora Group of Michigan, LLC | Security, Systems & Software paul@... | Unix/Linux - We don't

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

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

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

Thank's for the information,? finally we have succeed? ?comparing one 8341A with another having an attenuator, now the unit control the attenuator nicely, obviously the explanation in service

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,

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

One more discovery on this - it appears that the D-version (54200D) and A-version (54200A) used the same EPROM set. I have found the same labels in pictures online of motherboards from both versions,

Hi All Ok about the acronyms We had RPG Rotary Pulse Generator apparently this is the HMI control knob Human machine interface (a Knob ) or as I know it RPE rotary pulse encoder RUD new one for me but

Just a correction here. The connections I have made are: SA? ? ? ? ? ? ? PC (USB RS232 adapter) P1. GND? ? ?Unconnected P2. TxD? ? ? RxD P3. RxD? ? ? TxD P4. RTS? ? ? DCD P5. CTS?

I just run a test regarding your notes. You are correct when I set the DTR (+VE) from RealTerm I can see a T visible on the bottom right of the SA screen which I didn't notice in the past. When i
