Figure 79: Synchronous acceptor input trigger
Output characteristics:
• In addition to trigger events from other trigger objects, the digio.trigger[N].assert() and
tsplink.trigger[N].assert() functions release the line if the line is latched low. The pulse
width is not used.
• The physical line state does not change until all drives (internal and external) release the line.
• Action overruns occur if the internal drive is not latched low and a source event is received.

Synchronous trigger mode
The synchronous trigger mode is a combination of SynchronousA and SynchronousM trigger modes.
Use the Synchronous trigger mode for compatibility with older Keithley Instruments products.
Keithley Instruments recommends using SynchronousA and SynchronousM modes only.
Input characteristics:
• The falling edge generates an input event and latches the internal drive low.
