P7500 TriMode™ Probe Deskew
Procedures

Overview

Deskew aligns signals to compensate for differing signal
delays from cables of different lengths. The oscilloscope
deskew feature applies deskew correction after it
completes each acquisition. The deskew values do not
affect logic triggering. Deskew has no affect on XY and
XYZ display formats. In order to perform deskew with
the P7500 Series probes, the Tektronix Deskew Fixture
(Part Number 067-1586-00) shown in Figure 1 is
required.

Step-by-Step Procedures

1.
Connect the deskew fixture to a USB power source as shown in
Figure 2 with the other end of the USB cable plugged into the
oscilloscope.
2.
Connect the probes to the oscilloscope.
