External Digital Signal Event Trigger mode
A/D acquisition is performed in external digital event trigger mode (triggering the electrical signal
is the falling edge trigger). The maximum sampling rate per channel is 200 kHz, and A/D
acquisition of N data samples is performed. The acquisition mode can be categorized into two
types
Pre-Trigger (acquisition of N data samples)
The A/D data is continually collected and is temporarily stored in the memory on the PET-7H16M
until the trigger signal is received. Once the trigger signal is received, the collected N data samples
are then transferred to the Host PC.
Post-Trigger (acquisition of N data samples)
In this mode, the A/D acquisition of the N data samples is started once the trigger signal is
received.
