soft key. If ‘rising edge’ is selected, the signal of the trigger port is lo
gic high level when the output number ‘1’ is triggered. If selected as a ‘falling edge’, the
signal of the trigger port is at a logical low level when the output number ‘1’ is trigger
ed. If you select close, the trigger port has no signal output.
If the current function is Burst output, the triggered port will output the number ‘1’ during the
output of the burst signal, and the triggered port will output the number ‘0’ during the burst signal
is closed.
If the current function is frequency sweep and the trigger source is selected as ‘internal’, the
trigger port will output the number ‘1’ when the sweep starts, and the pulse width of the number ‘1’
is half of the total sweep time.
If the current function is a frequency sequence and the trigger source is selected as ‘internal’, the
trigger port will output the number ‘1’ when the sweep starts, and the pulse width of the number ‘1’
is equal to a duration time.
