Agilent E1439 Programmer's Reference
Functions listed alphabetically
age1439_lbus_mode
Sets the local bus transmission mode (Agilent E1439D only) . This description also includes the
query:
age1439_lbus_mode_get gets the current local bus mode.
VXI plug&play Syntax
#include "age1439".h
ViStatus age1439_lbus_mode(ViSession id , ViInt16 lbusMode );
ViStatus age1439_lbus_mode_get(ViSession id , ViPInt16 lbusModePtr );
Description
age1439_lbus_mode sets the local bus to either generate, append, insert or pipeline data. The data
port must be set to the local bus with the age1439_data_port function ( See “age1439_data_
setup” on page 90 ) before these modes take effect.
Parameters
id is the VXI instrument session pointer returned by the age1439_init function.
lbusMode selects the transmission mode of the local bus when it is enabled by the age1439_data_port
function.
AGE1439_GENERATE forces the module at id to generate data only, not passing through data
from other modules on the local bus.
AGE1439_APPEND causes the Agilent E1439 to pass data through from modules on its left and
append its data to the end.
AGE1439_INSERT causes the Agilent E1439 to place its data on the local bus and then pass data
through from modules on its left.
AGE1439_PIPELINE causes the Agilent E1439 to pipe data through from modules on its left
without appending or inserting its own data. The state of this parameter is unaffected by switching
back and forth between the local bus and the VME backplane with the
age1439_data_port
function.
