:LA:TCALibrate

Syntax
:LA:TCALibrate <tcal>
:LA:TCALibrate?
Description Sets or queries the delay calibration time of the digital channel. The default unit is s.
Parameter Name
<tcal>
Remarks When you use an oscilloscope to make actual measurements, the transmission delay
of the probe cable may bring relatively greater errors (zero offset). Zero offset is
defined as the offset of the crossing point (between the waveforms and the threshold
level) from the trigger position. You can set a delay time for calibrating the zero offset
of the corresponding channel.
Return The query returns the delay calibration time in scientific notation.
Format
Example :LA:TCALibrate 0.00000002
