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_enable
= a Boolean value indicating whether the timer is enabled as a trigger event. If a “1” is returned for
this parameter, the timer is enabled as a trigger. If a “0” is returned for this parameter, timer triggering is disabled.
immediate
= a Boolean value indicating whether immediate is enabled as a trigger event. If a “1” is returned for this
parameter, immediate triggering is enabled. If a “0” is returned for this parameter, immediate triggering is disabled.
alarm
= a Boolean value indicating whether the LXI alarm is used as an ARM event. If a “1” is returned for this
parameter, the LXI alarm can act as an arm event. If a “0” is returned, the LXI alarm is not a valid arm event.

ESCRIPTION
This function returns the enabled trigger source events. Regardless of the response, software triggers are always
enabled. For the
vtb_masks
,
dio_masks
, and
lan_masks
parameters, the data items in these arrays are ordered as
follows: positive edge, negative edge, positive level, negative level. For the
lan_masks
parameter, however, the
positive and negative level are not supported with LAN events and these bits are ignored.
NOTE
This function supersedes the vtex1048_get_trigger_source
() function found in the EX1048A.
