
Pulse Mode: Changes the system’s output mode to Continuous, Single Shot, Burst, or
Duty Cycle.

Period: Sets the System’s T
0
period. Valid inputs are 40ns –4000s set in 4ns
increments.

Duty Cycle: If Duty Cycle has been selected in the System’s Pulse Mode, the unit will
generate a continuous pulse stream in which outputs will be On for “N” pulses and Off
for “M” pulses. One may alters the “N” (On) and “M” (Off) parameters:
 On Counts (“N”): Positive integer value which designates the number of
pulses to produce during the “On Cycle.” Valid inputs are 1-1,000,000.
 Off Counts (“M”): Positive integer value which designates the number of
pulses to suppress during the “Off Cycle.” Valid inputs are 1-1,000,000.
o NOTE: The number of cycles which the duty cycle sequence will execute may be
altered. For more Information, see the “Enhanced Options” section.

Burst Count: If Burst mode has been selected in the System’s Pulse Mode, the Burst
Counts positive integer input selects the number of T
0
pulses generated once the
Run/Stop button has been pressed. Valid inputs are 1-1,000,000.

Run: Enables or disables the output for all channels. This command is the same as
pressing the Run/Stop button.

Auto Start: Enables or disables the Auto Start function. If enabled, the unit will start
pulsing immediately upon power-up or be in an armed state if in external mode.

External Trigger/Gate: Selects the system’s External Mode to be Disabled, Triggered,
or Gated. If either Triggered or Gated is selected, the following sub -parameters may be
set.
o Threshold (V): Sets the trigger threshold Voltage in 10mV increments. Typically
this value should be set to 50% of the incoming trigger voltage for optimum
trigger response. Valid threshold values are 0.20V-15V. The unit can handle up
to a 30V peak maximum external input.
o Polarity: If the External Mode has been set to Gated, change the Polarity to the
required polarity. Active low or active high are the available modes.
o Trigger Edge: If the External Mode has been set to Triggered, change the
Trigger Edge to the required transition. Rising or falling edge are the available
modes.
