Enabling System Trigger or Gate
Enables the use of the trigger input by the system timer as a trigger source or a
gate source (within the Gate/Trig menu):
• EXTin:
Selects between disabling the use of external inputs
and setting the system trigger mode to trigger or gate
mode.
• Level:
Sets the trigger threshold.
• Gate:
Selects between active high and active low when the
gate mode is selected.
• Edge:
Selects between rising edge and falling edge as the
trigger source when the trigger mode is selected.
*NOTE: When the gate disables the System Timer, the timer is reset. The
gate edge, to enable the timer, will restart the System Timer which
synchronizes the T
0
pulse to the gate and minimizes jitter relative to the
gate. The trigger threshold applies to all uses, channel and system, of the
trigger/gate input.
