Gate:
Enables the GATE input for the channel by setting the
method of output control used with the gating
function.
Logic:
Sets the logic level used with the gating function,
either active high or active low.
“Pulse Inhibit” method
T
he gate prevents the channel from being triggered by the channel’s
trigger source pulse. If a pulse has already started when the gate disables
the channel, the pulse will continue normal output but will not restart on
the next trigger pulse.
“Output Inhibit” method
The gate leaves the base triggering alone and enables/ disables the
output directly.
