Commands by Subsystem
:TRIGger:DURation:PATTern
(see page 786 )
Command Syntax
:TRIGger:DURation:PATTern <value>, <mask>
<value> ::= integer or <string>
<mask> ::= integer or <string>
<string> ::= "0xnnnnnn"; n ::= {0,..,9 | A,..,F}
The :TRIGger:DURation:PATTern command defines the specified duration
pattern resource according to the value and the mask. For both <value>
and <mask>, each bit corresponds to a possible trigger channel. The bit
assignments vary by instrument:
Set a <value> bit to "0" to set the pattern for the corresponding channel to
low. Set a <value> bit to "1" to set the pattern to high.
Set a <mask> bit to "0" to ignore the data for the corresponding channel.
Only channels with a "1" set on the appropriate mask bit are used.
Query Syntax
:TRIGger:DURation:PATTern?
The :TRIGger:DURation:PATTern? query returns the pattern value.
Return Format
<value>, <mask><NL>
<value> ::= a 32-bit integer in NR1 format.
<mask> ::= a 32-bit integer in NR1 format.
