Specifications
Arm and Trigger
Each Arm event gates 1 or more trigger events. Each Trigger event causes acquisition of data into a single
record at the configured sample rate. The number of data records is configurable from 1 to 1024.
1. EXTernal can be used as an ARM source or a Trigger source, but not both at the same time.
2. OR can not be used if the EXTernal source is being used as an ARM source.
