Internal Pacer Trigger Connection

USB-4716 provides two 16-bit counters connected to a 10 MHz clock. Counter 0 is a
counter that counts events from an input channel. Counter 1 is a 16-bit timer for
pacer triggering. A low-to-high edge from the Counter 1 output will trigger an A/D
conversion on USB-4716.
3.5.2

External Trigger Source Connection

In addition to pacer triggering, USB-4716 also allows external triggering for A/D con-
versions. When GATE is connected to a +5V DC source, the external trigger function
is thereby disabled. The external trigger function will be enabled once the +5V DC
source is removed.
