age1439_clock_setup
Sets all timing parameters for commonly used measurement setups. This description also includes
a query:
age1439_clock_setup_get
VXI plug&play Syntax
#include "age1439".h
ViStatus age1439_clock_setup(ViSession id , ViInt16 clockSetup );
ViStatus age1439_clock_setup_get(ViSession id , ViPInt16 clockSetupPtr );
Description
age1439_clock_setup is used to select the source and distribution of clocking and
synchronization signals used by the Agilent E1439 module. The primary clock signal used by the
module is the ADC clock, for which the rising edges indicate the time for each sample of the
analog-to-digital converter.
This function changes the settings controlled by the following lower-level functions:
age1439_adc_clock
age1439_adc_divider
age1439_front_panel_clock_input
age1439_reference_clock
age1439_reference_prescaler
age1439_smb_clock_output
age1439_sync_clock
age1439_sync_direction
age1439_sync_output
age1439_vcxo
Note
Setups using the external sample clock require that you use age1439_clock_fs to supply the clock
frequency.
Parameters
id is the VXI instrument session pointer returned by the age1439_init function.
clockSetup This parameter provides a quick way to set up most of the timing parameters for several standard
clock configurations. The following setups are available:
