Δ
t
= Typically 50 ns, see data sheet (trigger delay between the trigger and the sync
signal start)
delay = "Double Pulse Delay = 200 ns"; the first pulse starts without a delay
PW
= "Double Pulse Width = 100 ns"
"Ext Single"
Generates the signal triggered by an external trigger event.
"Ext Gated"
Generates the signal triggered by an external gate signal.
Example: Generation of single pulse signal ("Pulse Mode = Sin-
gle") using "Trigger Mode = Ext Gated"
1
= External trigger signal input with "Trigger Input Polarity = Normal" (the positive
slope is active)
2
= Sync signal
3
= Pulse signal
Δ
t
= Typically 50 ns, see data sheet (trigger delay between the trigger and the
sync signal start)
delay = "Pulse Delay = 100 ns"
PW
= "Pulse Width = 100 ns"
period = "Pulse Period = 300 ns" (time between the pulse start of two consecutive pul-
ses)
a
= Gate active duration (pulses are generated during the gate active part)
Remote command:
[:SOURce<hw>]:PULM:TRIGger:MODE
Pulse Period
Sets the repetition rate of the generated pulse signal.
Remote command:
Pulse Width
Sets the pulse duration of the generated pulse signal.
Note:
The pulse width must be at least 20 ns less than the set pulse period.
Remote command:
