24 :POWer Commands
:POWer:DESKew
(see page 1138)
Command Syntax
:POWer:DESKew
The :POWer:DESKew command launches the auto deskew process on the
oscilloscope.
Before sending this command:
1 Demagnetize and zero- adjust the current probe.
Refer to the current probe's documentation for instructions on how to
do this.
2 Make connections to the U1880A deskew fixture as described in the
oscilloscope's connection dialog or in the DSOX3PWR Power
Measurement Application User's Guide.
3 Make sure the voltage probe and current probe channels are specified
appropriately using the :POWer:SIGNals:SOURce:VOLTage1 and
:POWer:SIGNals:SOURce:CURRent1 commands.
The deskew values are saved in the oscilloscope until a factory default or
secure erase is performed. The next time you run the Power Application,
you can use the saved deskew values or perform the deskew again.
Generally, you need to perform the deskew again when part of the test
setup changes (for example, a different probe, different oscilloscope
channel, etc.) or when the ambient temperature has changed.

NOTE
Use the lowest attenuation setting on the high voltage differential probes whenever
possible because the voltage levels on the deskew fixture are very small. Using a higher
attenuation setting may yield inaccurate skew values (and affect the measurements made)
because the noise level is magnified as well.
