External Trigger Out
Trigger Out selects one of the eight lines from trigger bus (TRIG [0..7]) as an
external trigger source. The selection of the trigger out line is done by the USB
device in the chassis as illustrated in Figure 2-2 by means of a multiplexer.
Table 2-2 defines the available trigger out signals provided by U2300A, U2500A,
and U2600A Series DAQ, whereas for U2700A Series modular products, user is
allowed to choose any trigger line from the trigger bus (TRIG [0..7]) as an external
trigger source.
The SCPI command below is used to select one of the lines or bits of the trigger
bus (TRIG [0..7]) as an external trigger source:
TRIGger:OUT {0|1|2|3|4|5|6|7}
