Vertical attenuator skirted knobs
Few things are as frustrating as when the vertical knob on a Tek scope is damaged, by cleaning (hah, you didn't know the printing washed right off, did you?) or mechanical wear or other damage. Many d

Rather than a TM500 module extender....
I just want to mention again that all the issues raised with regard to module extenders are important, and no matter which route you go, the result is always a bit sub-optimal, and awkward on the benc

The post-demise sale of guys with lots of gear is always a bit sobering. Part of the reason Suzie and I are running the Stuff Season event is to help move useful bits out to anybody that can use them,

93 Ohm feed-thru terminators - Unobtanium? No, as it turns out.
Following this thread, I remembered that I had some odd BNC terminators in my accessory drawer. I just fished them out, and they are ELCOM FT-90, BNC (m-f) terminators and measure between 91.2 and 93
