ViStatus age1439_lbus_reset_get(ViSession id,ViPInt16lbusResetPtr);

Description

In order to avoid glitches in the local bus data, the local bus interface has strict requirements as to

the order in which modules in a VXI mainframe have their local bus interface reset. Upon power-

up or whenever any single module in the mainframe is put into a reset state, all modules should be

placed into the reset state from left to right. Then all modules can be take out of reset from left to

right.

Parameters

id is the VXI instrument session pointer returned by the age1439_init function.

lbusReset puts the Agilent E1439's local bus into reset or takes it out of reset.

AGE1439_LBUS_RESET_ON puts the Agilent E1439's local bus into reset while AGE1439_

LBUS_RESET_OFF takes the Agilent E1439 out of reset.

lbusResetPtr points to the current value of the lbusReset parameter.

Return Value

AGE1439_SUCCESS indicates that a function was successful.

Values other than AGE1439_SUCCESS indicate an error condition or other important status

condition. To determine the error message, pass the return value to “age1439_error_message” on
