:TRIGger:DURATion:TYPe
Syntax
:TRIGger:DURATion:TYPe <pa_ch1>[,<pa_ch2>]
:TRIGger:DURATion:TYPe?
Description
Set or query the pattern of each channel of duration trigger.
Parameter
Name Type Range Default
<pa_ch1> Discrete {H,L,X} X
<pa_ch2> Discrete {H,L,X} X
Explanation
The patterns consist of 2 analog channels.
<pa_ch1> and <pa_ch2> set the patterns of analog channels CH1 and CH2. Users can send 2
parameters to set the pataterns of the two channels. Also, you can omit the parameter <pa_ch2> to
set the pattern of CH1 (the pattern state of CH2 remains unchanged). No matter whether the
parameters are omitted, the query command returns the currently set pattern for all the channels.
In the range of the parameter, H represents high level (higher than the threshold level of the
channel). L represents low level (lower than the threshold level of the channel). X denotes that this
channel is ignored (this channel is not used as a part of the pattern. When all the channels in the
pattern are set to X, the oscilloscope will not trigger).
Please distinguish "omit parameter" from "ignore channel". The former means that the parameters
corresponding to some channels are not sent when sending the command, and the pattern states of
these channels remain unchanged. The latter means that the channel is set to X when sending the
command, and the state of this channel is ignored when the instrument judges the patterns.
Return Format
The query returns the currently set patterns for all the channels (2) of duration trigger.
Example
:TRIGger:DURATion:TYPe L /*Set the pattern of CH1 to L, and the pattern state of CH2 remains
unchanged*/
:TRIGger:DURATion:TYPe? /*The query returns L,X*/
