To compensate or calibrate probes you must connect the Probe Calibration and
Deskew Fixture to the instrument; use the procedure in the manual that came

To compensate the instrument so that it can take accurate measurements based on
the ambient temperature, use the procedure in the manual that came with the
deskew fixture you are using (see Figure 3--41).
You can adjust a relative time delay for each channel. This lets you align the
signals to compensate for signals that may come in from cables of differing
lengths. The instrument applies deskew values after it completes each acquisi-
tion; therefore, the deskew values do not affect logic triggering. Also, deskew
has no affect on fast acquisition XY and XYZ display formats.
To deskew channels, use the procedure in the manual that came with the deskew
fixture you are using (see Figure 3--41).
Select Display Only On with deskew for the fastest measurement and math
throughput. Select Display Only Off with deskew for the most accurate
measurements and math. See the online help for more information.
