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.

VXIplug&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.
