a. This trigger is option is not supported for the DT9837B module.
b. On the DT9837A and DT9837C, you can use the external trigger to trigger D/A subsystem 0.
c. If you choose a threshold trigger for the start trigger on the DT9837, the threshold level is fixed at 1.0 V and the
threshold channel is analog input channel 0.
If you choose a threshold trigger for the start trigger on the DT9837A or DT9837B, you can program the
threshold level from 0.2 V to 9.8 V and the threshold channel is analog input channel 0.
If you choose a threshold trigger for the start trigger on the DT9837C module, you can program the threshold
level as a value between ±10 V for a gain of 1 or ±1 V for a gain of 10, and any of the supported analog input
channels can be used as the threshold channel.
d. On the DT9837A and DT9837C, you can use the analog threshold trigger to trigger D/A subsystem 0.
e. The DT9837C supports a negative threshold trigger.
f. On the DT9837A, you can use analog input channel 0 as the analog threshold trigger channel to start analog
output operations. On the DT9837C, you can use any of the analog input channels as the threshold trigger
channel to start analog output operations.
