:LA:SIZe
Command format
:
:LA:SIZe {SMALl|LARGe|MEDium}
:LA:SIZe?
Functional description
:
This command is used to set or query the display size of the opened channel waveform on the screen.
Return format
:
Query returns SMALl, LARGe or MEDium.
For example
:
:LA:SIZE SMALl
Set the waveform display size to small.
:LA:SIZE?
Query returns SMALl.
:LA:TCALibrate
Command format
:
:LA:TCALibrate <tcal>
:LA:TCALibrate?
Functional description
:
This command is used to set or query the delay calibrating time of the digital channel. The default unit is
s.
<tcal>: real model, -100ns to 100ns.
Transmission delay of probe cable may cause greater error (zero offset) when use the oscilloscope to
operating autual measuring. Zero offset is defined as the offset of the intersection of the waveform and
the threshold level line with respect to the trigger position. User can set a delay time to calibrate the zero
offset of the corresponding channel.
Return format
:
Query returns the delay calibrating time in scientific notation.
For example
:
:LA:TCALibrate 20ns
Set delay calibrating time to 20ns.
:LA:TCALibrate?
Query returns 2.000000E-8.

:LA:DELete?
Functional description
:
Cancel any one of group setting of 16 digital channels or cancel any one of group setting of GROup1-GROup4.
This command can only cancel the group setting operation for digital channels or custom channel groups
that have been grouped.
Return format
:
