Command Syntax
TRIGger:SOURce <source>
Command Parameters

may be used.
INTernal <channel> = All outputs are updated when the selected channel is updated (all
other channels wait for the selected channel to update).
AUTO
= A DAC output is immediately updated when the channel is
programmed. The second event is not required to update the
output voltage
EXTernal
= Selects the front panel trigger input and all channels are updated
(all other channels wait for the selected channel to update).
TTLTrig<n>
= All outputs update when the selected TTL trigger line goes active.
*RST Value
AUTO

Query Response
<source> = AUTO | EXT | INT 1 - 16 | TTLT 0 - 7 (for VM3616A)
<source> = AUTO | EXT | INT 1 - 8 | TTLT 0 - 7 (for VM3608A)
Description
The Trigger Source command is used to select the source that updates the DACs on the
VM3608A/3616A. Each DAC is double buffered. Therefore, writing to the DAC
(source:voltage:data or source:voltage:level) will require a second event to cause the
output voltage to be updated. This command selects the source of the update event.
When using SCAN, a trigger source of either EXTernal or one of the TTLTriggers is
required. This command is used to select that source.
The query reports the source of the update event that was selected.
