Overview
This fixture converts the TDS7000 Series PROBE
COMPENSATION output into a set of test points
that give you a convenient way to:
H Compensate a passive probe (low-frequency).
H Optimize the oscilloscope gain and offset
accuracy at the probe tip.
H Compensate for timing differences between
two, three, or four voltage probes (deskew).
H Compensate for timing differences between
one, two, or three voltage probes and a current
probe (deskew).
Connecting to the Oscilloscope
The fixture has two BNC inputs, A and B. Use the
BNC cable (included) to connect the oscilloscope
PROBE COMPENSATION output to either the A
or B input. The input you use depends on the type
of probes you have and the operation you want to
perform.

Connecting Probes
WARNING.
while connecting probe tips to the square
pins on the fixture. The ends of the square
pins are sharp.
The following diagrams show how to attach each
type of probe tip to the fixture. Refer to the
ground symbols screened on the fixture to
establish the correct polarity.
P6139A
Connect the probe tip and the ground lead to the
two terminals as shown.
