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 external input.
o
Gate Polarity:
If the External Mode has been set to Gated, alter the Gate 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, alter the Trigger
Edge to the required transition. Rising or falling edge are the available modes.
Channels Section
The Channels Section of the 9200 application
only affects the 9200’s channel parameters.
Complex pulse trains can be created by combining various system and channel modes. As
shown below in Figure 6.3, the following channel parameters may be altered:

–9200 Application: Channel Parameters
Channel Selection:
Select the proper Channel tab in order to further edit the
parameters on the corresponding channel.
Enabled:
Enables and Disables the output for the selected channel.
Delay:
Sets the delay from the timing reference to when the pulse is created. Valid
input is
±
1000s with 10ns increments. Note: negative delays are only applicable if you
are referenced to a channel that has a positive delay.
Width:
Sets the pulse width for the selected channel. Valid input is 10ns
– 1000s with
10ns increments.
Amplitude:
Allows the user to select the voltage amplitude of the output. Valid values
are 3.3V
– 5V with 20mV increments.
