"Ext Triggered" Generates the signal each time an external trigger event occurs.
Example: Generation of single pulse signal ("Pulse Mode = Sin-
gle") using "Trigger Mode = Ext Triggered"
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"
Example: Generation of double pulse signal ("Pulse Mode = Dou-
ble") using "Trigger Mode = Ext Triggered"
1
= External trigger signal input with "Trigger Input Polarity = Normal" (the positive
slope is active)
2
= Sync signal
3
= Pulse signal
a
= Trigger signal during double pulse generation is without effect
