Functions listed alphabetically

age1439_sync_direction

Selects front or rear panel availability of the sync signal. This description also includes the query function:

age1439_sync_direction_get

VXIplug&play Syntax

#include "age1439".h

ViStatus age1439_sync_direction(ViSession id, ViInt16 syncDirection); ViStatus age1439_sync_direction_get(ViSession id, ViPInt16 syncDirectionPtr);

This command should be used only for specialized custom clock requirements. Most useful clock setups can be supplied by age1439_clock_setup.

Description

This function determines whether the front or rear panel sync signal is available to the other panel.

Parameters

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

AGE1439_SYNC_FRNT_TO_REAR specifies that front panel sync signal be available on the VXI backplane (rear panel).

AGE1439_SYNC_REAR_TO_FRNT specifies that the VXI backplane sync signal be available on the front panel SMB sync connectors.

Returns a pointer to the current value of syncDirection.

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 page 102.
