VXIplug&play Syntax

#include "age1439".h

ViStatus age1439_front_panel_clock_input(ViSession id, ViInt16 fpClock); ViStatus age1439_front_panel_clock_input_get(ViSession id, ViPInt16 fpClockPtr);

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 selects a front panel clock source that is used to drive the analog to digital converter (ADC) for single module operation or when a module is used as the master ADC clock source for a multi-module system.

Parameters

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

AGE1439_CLOCK_OFF specifies no front panel source.

AGE1439_SMB_CLOCK specifies clock input from the front panel Intermodule Clock/SMB connectors.

AGE1439_BNC_CLOCK specifies clock input from the front panel Ext Clock/Ref BNC connector.

returns a pointer to the current value of fpClock.

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.
