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.
lan_masks
= an array of four 8-bit integer values representing the enabling of LAN events from any of the eight
LAN events. Within the 8-bit field, the MSB corresponds to LAN 7 and the LSB corresponds to LAN 0. Valid input
values: 0 (0x00h) through 255 (0xFFh).
timer
= 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.
alarm
= a Boolean value indicating whether the LXI alarm is used as an ARM event. If a “1” is set for this
parameter, the LXI alarm can act as an arm event. If a “0” is set, the LXI alarm is not a valid arm event.

ALUE
The trigger source is set to timer.
D
ESCRIPTION
This function sets the trigger source events. Regardless of this setting, software triggers are always enabled.
NOTE
It is necessary to explicitly call vtex10xxA_set_alarm_enable to enable timer events even when the
alarm
parameter is set to TRUE.
