HP8596E input step attenuator

Hello,

 

Recently I got a HP8596E with faulty step attenuator (33321-60037). I have three qestions regarding the attenuator unit:

- what attenuator pads are incorporated into 33321-60037? The 20-dB one in my unit is made on white substrate, whereas the other ones are made on transparent glass substrates. Is this an original arrangement, or an effect of non-authorized repair?

- I believe that in these attenuators the plunger tips were originally secured with little epoxy drop, am I right?

- I have also noticed some lubricant remains on the contct strips. Which parts inside the attenuator were originally lubricated and with what kind of lubricant?

 

Regars,

RW
