VXIplug&play Syntax
#include "age1439".h
ViStatus age1439_vxi_clock_output(ViSession id, ViInt16 vxiClock);
ViStatus age1439_vxi_clock_output_get(ViSession id, ViPInt16 vxiClockPtr);
Note
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 which clock the module should use to drive it’s VXI clock.
Parameters
id is the VXI instrument session pointer returned by the age1439_init function.
vxiClock AGE1439_FRONT_PANEL_CLOCK specifies that the specified front panel clock drive the VXI
clock.
AGE1439_CLOCK_OFF specifies not driving vxi clock on the backplane.
AGE1439_DIVIDED_ADC_CLOCK specifies using the divided ADC clock to drive the vxi
clock.
vxiClockPtr Returns a pointer to the current value of vxiClock.
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
