P6330 3.5 GHz Differential Probe Instruction Manua l

Probe Calibration Fixture

Some of the procedures in this manual use a probe calibration

fixture, Tektronix part numbe r 067-0419-00.

The calibration fixture provides a means to test the probe for both

common mode and differential mode measurements. SMA

connectors allow stimulus signals to connect to the fixture and are

located on the front and bac k of the fixture. The fixture is designed

to be used with a probe positioner, such as a Tektronix PPM203B.
