I have several attenuators from a different series. Substrate marking is below.
I'm working on an SPC problem on a 784A at the moment and think I have successfully fixed it by excersizing all the relays in a C# program and GPIB control. At first it was 50% success but realized I had not included the AC coupling relays, re-did it. 100 passes on the relays and it now passes SPC 100% for the last 10 tries.
Can you tell me what relay is used in the 784D? I was surprised to find the garden variety Aromats in the 784A. I expected more exotic but apparently they worked for Tek.
Substrate marked: H2365J (there is a parts site, Qservice, that references this for use in the TDS500 and TDS600 series but does not mention the TDS700)

I have a TDS784D where all four ceramic attenuator hybrids are cracked. I'm looking for replacements, and would like to know if any other models use compatible attenuators. Would the attenuators from a TDS744A work (even partially so I can check the rest of the scope)?
If anyone knows where I might be able to find them at a reasonable cost, I would love to hear from you. I'll take one with SPC problems since I know I can replace the relays.
