*DDT <arbitrary block program data>|<string program data>
The *DDT (Define Device Trigger) command determines the power meter's
response to a GET (Group Execute Trigger) message or *TRG common
command. This command effectively turns GET and *TRG into queries,
with the measured power being returned.
Syntax
*DDT
Parameters
Type
arbitrary block program
data
string program data
1. The <action> field of the parameter may contain:
2. The first digit after the # indicates the number of following digits. The following
digits indicate the length of the data.
Examples of <arbitrary block program data> parameters are:
• #15FETC? and #206FETCh?
Examples of <string program data> are:
• "FETCh1?", "FETCh?" and "TRIG1;FETC1"
Note *DDT does not support "FETCh1?" and "FETCh2?"
simultaneously.
