Choices: Free Run, Master Trigger, Magnitude
Default Value: On
Sets the mode of signal capture trigger.
Free Run
This choice starts capturing signal data as soon as the Play button is
pressed.
Master Trigger
This choice uses external triggers to start the signal capture session,
based on the current system settings in the PXB's System
> Clock And Trigger panel.
Note: If the system's Trigger Source is set to Software, signal capture will start immediately.
Magnitude
This choice triggers a signal capture based on the power level (trigger
value) of the incoming signal. Selecting Magnitude
enables the Trigger Value setting.
Range: 0 to 46340
Default Value: 0
Dependency: Enabled only when Trigger Type is set to Magnitude
Sets the power threshold for triggering a signal capture when Trigger Type is set to Magnitude.
Range: 0 to (depends on the capture sample
rate)
Default Value: 0 s
Dependency: Disabled when Trigger Type is set to Free Run
Displays and sets a time delay for a signal capture to begin after triggering. The delay is in seconds, and this value is also displayed in the Trigger Sample Delay setting in whole samples, based on the Signal Capture Sample Rate setting.
Range: 0 to 2147483647
Default Value: 0 Sa
Dependency: Disabled when Trigger Type is set to Free Run
Displays and sets a sample delay in whole samples for a signal capture to begin after triggering. This value is also displayed in the Trigger Time Delay setting in seconds, based on the Signal Capture Sample Rate setting.
Range: 0 to 100%
Default Value: 100%
Dependency: Disabled when Trigger Type is set to Free Run
Adjusts the position of the trigger relative to the window of sampled signal data, so that you can capture before, after, or on both sides of the trigger event. The PXB continuously stores a window of input sample data (up to 512 MSa, depending on your specified capture depth). trigger position specifies the position inside that window. Trigger position is fixed at 100% when Trigger Type is set to Free Run.
