Functions listed alphabetically
age1439_adc_clock
Specifies the ADC clock source. This description also includes the query function:
VXIplug&play Syntax
ViStatus age1439_adc_clock(ViSession id, ViInt16 adcClock);
ViStatus age1439_adc_clock_get(ViSession id, ViPInt16 adcClockPtr);
Note
This command should be used only for specialized custom clock requirements. Most useful clock
setups can be supplied by age1439_clock_setup.
Parameters
id is the VXI instrument session pointer returned by the age1439_init function.
adcClock AGE1439_VCXO_INTERNAL
freq determines which oscillator is used. age1439_vcxo determines whether the internal
oscillator is turned on. You must use all three of the functions to provide the desired internal clock
source.
AGE1439_VCXO_EXT_REF
phase-locked loop to convert it to the ADC clock of the module. The ADC clock can be either 100
MHz or 102.4 MHz. The external reference used by the phase lock loop to synthesize the ADC
clock can be either a 10 MHz or 10.24 MHz signal.
AGE1439_EXT_SAMPLE_CLOCK
reference_clock.
adcClockPtr points to the value of the current adcClock.
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
