Deskew Only
Pressing this button performs only the deskew calibration of the probe on the specified channel.

The Advanced Menu
The Advanced Menu contains information and functionality useful to the advanced user of the
TF-DSQ fixture. These include:

Risetime Skew Correction

Deskew All (or common deskew capability)

Common mode voltage settings for DC calibration
Rise Time Skew Correction
This field shows the signal risetime and the corresponding skew correction based on the signal
risetime.
When probes are deskewed, the risetime measurement of the edge used for deskewing is
displayed in the Rise Time field corresponding to the probe and probe channel, and an
additional skew correction of zero is applied.
The measured risetime of the signals encountered can be entered into the Rise Time field, and
the oscilloscope automatically calculates and applies a new skew correction value to be utilized
in addition to the deskew amount calculated during the deskew calibration procedure. With this
use, a finer deskew calibration is performed because the risetimes of the signals measured are
accounted for. See details of
risetime correction .
Deskew All (or Common Skew)
This is the deskew amount applied to all channels. The time entered in this field is the absolute
time by which all waveforms displayed by the oscilloscope are delayed in time. This value
effectively adjusts the zero time reference of the system. See
Probe Deskew Calibration for
details.
