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.
Figure 83: Synchronous input trigger
Output characteristics:
• In addition to trigger events from other trigger objects, the digio.trigger[N].assert() and
tsplink.trigger[N].assert() functions generate a low pulse for the programmed pulse
duration if the line is latched low, a falling edge does not occur.
• A normal falling edge pulse generates when the internal drive is not latched low and the
digio.trigger[N].assert() and tsplink.trigger[N].assert() functions are issued.
• To mirror the SynchronousA trigger mode, set the pulse width to 1 µs or any small nonzero value.
• Action overruns are disabled.
