:CHANnel<n>:TCAL
Syntax :CHANnel<n>:TCAL <val>
:CHANnel<n>:TCAL?
Description Set or query the delay calibration time of the specified channel to calibrate the zero offset
of the corresponding channel. The default unit is s.

<val> Real -100ns to 100ns 0.00s
Explanation <val> can only be set to the specific values in the specified step. If the parameter you
sent is not one of the specific values, the parameter will be set to the nearest specific
values automatically. The step varies with the horizontal timebase (set by
the
:TIMebase[:MAIN]:SCALe command), as shown in the table below.
Horizontal Timebase
Step of the Delay Calibration Time
5ns
100ps
10ns 200ps
20ns
400ps
50ns
1ns
100ns
2ns
200ns 4ns
500ns
10ns
1μs to 10μs
20ns
Note: When the horizontal timebase is equal to or greater than 10μs, the delay
calibration time cannot be adjusted.
Return
Format
The query returns the delay calibration time in scientific notation.
Example
:CHANnel1:TCAL 0.00000002 /*Set the delay calibration time to 20ns*/
:CHANnel1:TCAL? /*The query returns 2.000000e-08*/
