A trigger signal may be input from an external device.
The EXT_SAMP terminal (terminal No.: A8) initiates sampling with the
rising of a signal (active HIGH).
The maximum delay from the falling edge until activation is 100
μ
s.
Input Signal
Input a signal rising from LOW to HIGH to EXT_SAMP terminal (A8).
Sampling is done at a rising edge.
Input signals of up to 1KHz are available to activate the trigger.
