6.11 Applying an External Trigger (External Trigger)
160
An external signal applied to the External Control terminal can serve as a trigger
source. It can also be used to synchronously drive parallel triggering of multiple
instruments.
Triggering occurs by shorting the EXT TRIG terminal to the GND terminal, or by
an input signal falling from HIGH (3.0 to 5.0 V) to LOW (0 to 0.8 V) level. (Trig-
gering can also be set to occur by the input signal rising from LOW to HIGH
level.)

trol Terminals" (
