"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
= Trigger delay between the trigger and the sync signal start; see data sheet
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:
Double Pulse Width
Sets the width of the second pulse.
Remote command:
[:SOURce<hw>]:PULM:DOUBle:WIDTh
