Deskew Control Window
Access this control window from the Vertical menu Deskew command.
Overview
Use the Deskew control window to compensate for propagation delays
of different length probes connected to the vertical input channels.
To Use
Connect the probes to a signal source. Use the horizontal and vertical
controls to center the fastest signal on the screen. Click a channel button
at the top of the control window to select the slower channel. Use the
multipurpose knob to adjust the deskew time so that the two signals
align. To clear the deskew value, click Set to 0.0s.
Behavior
Each input channel has its own deskew settings. Deskew compensates
individual channels for probes or cables of different lengths. The
instrument applies the delay values after each completed acquisition.
The deskew values, which have a range of ±75 ns, do not affect
triggering or the XY display format.
The deskew values are saved as part of the instrument setup. The deskew values for the selected
channel will be retained until you change the probe, you restore a saved setup, or you recall the
factory setup.
Deskew is supported in Fast Acquisitions mode when you acquire one or two channels. If you
acquire three or more channels, the Fast Acquisition mode is turned off and the message, Deskew
not applied in FastAcq when three or more channels are acquired, is displayed. When you switch
back to acquiring one or two channels, the message, Deskew is re-enabled, is displayed and
deskew values are applied again.
