Probe Calibration Fixture
Some of the procedures in this manual use a probe calibration
fixture, Tektronix part number 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 back of the fixture. The fixture is designed
to be used with a probe positioner, such as a Tektronix PPM203B.

Ω
termination included with the fixture to the
unused SMA connector.
3.
Insert and secure the probe in a probe positioner.
4.
Position the probe over the fixture, using either the positioner
coarse adjustment or otherwise manipulating the positioner arm
in place.
