Description

Configures a TDR calibration so that the fixture length is automatically determined. This is the default setting. If you turn this setting off, use the following three commands to manually set the time window:

:TIMebase:SCALe

Sets the seconds-per-division on the display's x-axis.

:TIMebase:POSition

Sets the time value in seconds at the timebase reference which, by default, is two divisions from the left side of the display.

:TIMebase:REFerence

By default, the TDR time reference is set to the second division from the left edge of the display. Changing the reference to the center of the display is not recommended. The horizontal reference point defines a specific delay value relative to the trigger event.
