Skew compensation is typically determined empirically, using an oscilloscope and then set one time. That one-time
l
setup will then be valid until the DUT or test equipment configuration changes.
The value specified by this command is not stored in the instrument state. It is stored in non-volatile memory and is
l
not affected by
*RST.
FUNCtion:ARBitrary:SKEW:TIME [{< time >|MINimum|MAXimum}]
FUNCtion:ARBitrary:SKEW:TIME? [{MINimum|MAXimum}]
This command requires the IQ Player option.
Sets a small time difference between the channels to compensate for minor variations in timing at the connector out-
put plane or at the device under test (DUT). Note than
lists, and bursts.
Parameter
A floating point value in the range of ±4 ns. Default 0.
Set the skew time to compensate for channel 1 being behind channel 2 by 140 picoseconds:
FUNCtion:ARBitrary:SKEW:TIME 1.4e-10
FUNCtion:ARBitrary:SKEW ON
Channels may exhibit slight timing variations at the output connector plane due to variations in internal circuitry
l
between the two channels. They may exhibit slight timing variations at the device under test (DUT) due to var-
iations in signal paths, including such things as switches and cable lengths.
A positive value delays channel 2, and a negative value delays channel 1.

The value specified by this command is not stored in the instrument state. It is stored in non-volatile memory and is
