Rising edge master trigger mode
Use the rising edge master (RisingM) trigger mode (see the figure titled "RisingM output trigger") to
synchronize with non-Keithley instruments that require a
high pulse.
Input trigger detection is not
available in this trigger mode. You can use the RisingM trigger mode to generate rising edge pulses.
The RisingM trigger mode does not function properly if the line is driven low by an external drive.
Output characteristics:
•
Configured trigger events, as well as the
digio.trigger[
N
].assert()
and
tsplink.trigger[
N
].assert()
commands, cause the physical line state to float high during
the trigger pulse duration.
•
An action overrun occurs if the physical line state is high while a stimulus event occurs.

Rising edge acceptor trigger mode
The rising edge acceptor trigger mode (RisingA) generates a low pulse and detects rising edge
pulses (see the following figures).
Input characteristics:
•
All rising edges generate an input event.
