[Test-Equipment] HP 8552

[Gary Schafer]

The jumper is in the terminator plugs that go on the back of the 141T. If I
remember right the jumper has to be in place if you are using the 8553 rf
plug in but is not required for the 8554 plug in.
If you don't have the terminators that go into the jacks you can put a
jumper wire on the proper pins. It is the center conductors of two of the
coaxial connectors in the jacks. Don't short them to ground!
