To Select the Pulse Mode
Press Pulse  Source to select “Int” modulation source; press Mode to select
“Single”, “Double” or “Train” (option PUG-DSG3000).
 Single: only one pulse signal is generated for a pulse period. This is the default
pulse mode.
 Double: two pulse signals are generated for a pulse period. At this point, Delay
and #2 Width are available and you can set the delay and pulse width.
 Train: a plurality of pulse signals are generated for a pulse period. At this point,
Period, Width, Delay and #2 Width are grayed out and disabled. You can
press Train List to edit the desired pulse train.
NOTE: When “Ext” modulation source is selected, this menu is grayed out and
disabled. When selecting “Train” or editing “Train List”, you need to install the option

 Use the numeric keyboard to input the desired value and select the desired unit
from the pop-up unit menu or unit keys. You can also press Enter to select the
default unit (s).
 You can also use the knob to modify this parameter.
 The range of pulse period is from 40 ns to 170 s.
 The pulse period determines the repeating frequency of the internal pulse
modulating signal.
NOTE: When “Ext” modulation source or “Train” pulse mode is selected, this menu is
grayed out and disabled.
To Set the Pulse Width
The pulse width is the time that the pulse can hold at the maximum value.
Press Pulse  Source to select “Int” modulation source; press Mode to select
“Single” or “Double”. At this point, you can set the corresponding pulse width and
delay.
