*TRG
The product has no trigger capability. The command is ignored in this
instrument.
† Note: this command potentially requires a range change that may not be possible because
>0.5V is still present on either output 1 or output 2 terminals at the time the command is
executed; see section 7.6 for more information. In the event of failure, the Execution Error bit is
set in the ESR register and the error code 104 is set in the EER register; see section 12.2.7. It
is strongly recommended that these registers are checked following the use of this command.
