Modules

 Enabled
 The enabled state of a device trigger input determines whether an input is selected as trigger source.
 
 Kind
 The device trigger kind determines how the device trigger responds to the device trigger input signal.
 
 Info
 Information of a device trigger input can be obtained.
 

Functions

uint16_t DevTrGetInputCount (TpDeviceHandle_t hDevice)
 Get number of trigger inputs.
 
uint16_t DevTrGetInputIndexById (TpDeviceHandle_t hDevice, uint32_t dwId)
 Get index of trigger input by it's ID.
 

Detailed Description

A device can have one or more device trigger inputs, usually available as pins on an extension connector on the instrument.

Use the function DevTrGetInputCount to determine the amount of available device trigger inputs. To use a device trigger input as trigger source, use the function DevTrInSetEnabled to enable it.
