FUNCTION PROTOTYPE
ViStatus vtex10xxA_set_trigger_source(ViSession vi,ViInt16 vtb_masks[],ViInt16 dio_masks[],ViBoolean
timer_enable,ViBoolean immediate);
FUNCTION PARAMETERS
vi = contains a session handle to the instrument. This handle is obtained by the function and remains valid until the
session is closed.
vtb_masks = a return array of four 8-bit integer values representing the enabled state of trigger events from the eight
channels of the trigger bus. Within the 8-bit field, the MSB corresponds to VTB channel 7 and the LSB corresponds
to VTB channel 0. Valid input values: 0 through 255.
dio_masks = a return array of four 8-bit integer values representing the enabled state of trigger events from the eight
channels of the digital I/O port. Within the 8-bit field, the MSB corresponds to DIO channel 7 and the LSB
corresponds to DIO channel 0. Valid input values: 0 through 255.
timer_enable = a Boolean value indicating whether the timer is enabled as a trigger event. If this parameter is set to
“1”, the timer is enabled as a trigger. If set to “0”, timer triggering is disabled.
immediate = a Boolean value indicating whether immediate is enabled as a trigger event. If this parameter is set to
“1”, immediate triggering is enabled. If set to “0”, immediate triggering is disabled.
