User skew
If enabled, the "Skew offset" value is used for compensation.
Remote command:
CHANnel<m>:SKEW:MANual
on page 1384
Skew offset
Sets a delay value, that is known from the circuit specifics but cannot be compensated
by the instrument automatically. It affects only the selected input channel.
The offset range and possible values depend on Extend user skew .
Remote command:
CHANnel<m>:SKEW:TIME
on page 1384
Probe skew
Measures the skew of all connected active probes and includes it in the total skew off-
set.
"Use probe group delay ..."
If enabled, the skew of all connected active probes is measured, dis-
played, and used for deskewing. The setting affects all active chan-
nels.
"Active probe" Shows the type of the probe that is connected to the selected chan-
nel.
"Probe group
delay" Shows the result of the probe skew measurement on the selected
channel.
Remote command:
PROBe<m>:SKEState
on page 1385
Total skew offset
If Extend user skew is disabled, the sum of the measured "Probe group delay" and the
"Skew offset" is shown. If "Use skew offset" is disabled, the skew offset is ignored.
If Extend user skew is enabled, only the probe skew is shown, and the skew offset is
always ignored.
Extend user skew
Allows you to set higher value in "Skew offset" to compensate for the delay of the mea-
surement setup. Without extension, the deskew range is
±
100 ns, and delays shorter
than the sample interval can be compensated.
With extension, the maximum delay is
±
1 s, and the instrument can compensate com-
plete samples. Compensation takes effect after the trigger. The maximum number of
acquisitions in the memory is reduced.
Use the extended skew range to compare signals: One signal goes directly from the
generator to the scope, and the other signal goes from the generator through the DUT
to the scope. The delay of the DUT is higher than
±
100 ns.
