Astronics Test Systems Operation 5-7
The
Gate and Trigger
subwindow is shown below:
Figure 5-9, Gate and Trigger Subwindow
This window allows the user to enable or disable the gate operation for the pulse
generator. It also allows the user to select whether the gate mode is synchronous
or asynchronous. In addition, it allows the user to select which input acts as the
gate and which input acts as the trigger.
The gate input selection options are:

Ignore gate – same as setting the gate to disabled

Front Panel signal A (high level). A high level on the IN 1 A input (for PGEN
#1) or IN 2 A input (for PGEN #2) enables the pulse output. A high level
means that the voltage at the input is above the programmed threshold by the
“Input A threshold” setting of the “Front Panel Inputs” configuration window.

Front Panel signal A (low level). A low level on the IN 1 A input (for PGEN #1)
or IN 2 A input (for PGEN #2) enables the pulse output. A low level means
that the voltage at the input is below the programmed threshold by the “Input A
threshold” setting of the “Front Panel Inputs” configuration window.

Front Panel signal B (high level). A high level on the IN 1 B input (for PGEN
#1) or IN 2 B input (for PGEN #2) enables the pulse output. A high level
means that the voltage at the input is above the programmed threshold by the
“Input B threshold” setting of the “Front Panel Inputs” configuration window.

Front Panel signal B (low level). A low level on the IN 1 B input (for PGEN #1)
or IN 2 B input (for PGEN #2) enables the pulse output. A low level means
that the voltage at the input is below the programmed threshold by the “Input B
threshold” setting of the “Front Panel Inputs” configuration window.

Backplane Trigger A (high level). A logic 1 level on the currently selected M
Trigger A input enables the pulse.

Backplane Trigger A (low level). A logic 0 level on the currently selected M
Trigger A input enables the pulse.

Backplane Trigger B (high level). A logic 1 level on the currently selected M
Trigger B input enables the pulse.
