The key caps should just pull straight off the switches.

Exactly - 10Mhz will be a typical cutoff for those efforts.

I have some Samtec SMA's that I can use to solder a splitter together rather quickly. I feel like this learning curve will visually reveal characteristics of components and circuits that are otherwise rather mysterious and hard to understand. Somehow.....this is fun even though it is technically for work. As it is said.....'love what you do and never work another day in your life'

I have a ZS1000, AP020, a differential AP034, and an AP022.  They see use in roughly that order...  With the powered BNC adapter, mainly the AP020 or AP022.  (The AP022 isn't recommended for use with the ADPPS, due to lack of offset zeroing, but it seems to zero just fine for me... But I wouldn't get it for that purpose.)

Does anyone know which style of panel N-Connector HP used for the 35677-63504 / 35677-63502 "Directional Bridge Assemblies" (75/50Ohm) and if somthing similar is still available?
