on the rear panel. Each time a TTL pulse signal of the specified polarity is received, the
source initiates a pulse modulation within its active level. At this point, the ―Trig Polarity‖
setting will be displayed and the ―Trig Slope‖ setting will be hidden.
2.4.4.12 Trigger Delay
The trigger delay indicates the delay from the receipt of the external trigger signal to the
start of the first pulse. This parameter can be set by touching screen keyboard or pressing
the front panel keypad.
Note: This setting item will be hidden when the modulation source is ―Ext‖ or the pulse
trigger is not ―Ext Trig‖.
2.4.4.13 Trigger Slope
The default is ―Positive‖, click the drop-down box to switch the trigger slope.
 Positive: Trigger a pulse when the positive slope of the external trigger signal arrives.
 Negative: Trigger a pulse when the negative slope of the external trigger signal
arrives.
Note: This setting item will be hidden when the modulation source is ―Ext‖ or the pulse
trigger is not ―Ext Trig‖.
2.4.4.14 Trigger Polarity
The default is ―Normal‖; click the drop-down box to switch the trigger polarity type.
 Normal: Trigger a pulse modulation during the effective time when the external gate
signal is high.
