VXI plug&play Syntax
#include "age1439".h
ViStatus age1439_reference_prescaler(ViSession id , ViInt16 refPrescaler );
ViStatus age1439_reference_prescaler_get(ViSession id , ViPInt16 refPrescalerPtr );
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 should generally be left in the default mode. The alternate mode applies to a
different model of the module.
Parameters
id is the VXI instrument session pointer returned by the age1439_init function.
refPrescaler AGE1439_PRESCALE_BY_1 divides the reference clock by one.
AGE1439_PRESCALE_BY_4 divides the reference clock by four.
refPrescalerPtr Returns a pointer to the current value of refPrescalerPtr .
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
