This VI sets the hardware clocking source of the device. The source can be either
software_convert, internal, ext_rising_edge or ext_falling_edge.

Device Handle (0) Device Handle is a numeric value that is used to identify the device
subsystem. The default Device Handle is 0.

Clock Source (SW_CONV:0) Clock Source is a numeric value that sets the hardware
clocking source of the device. The available options are:

0:SOFTWARE_CONVERT Software polled acquisition
1:INTERNAL On-board clocking
2:EXT_RISING_EDGE External clocking rising edge
3:EXT_FALLING_EDGE External clocking falling edge
4:MMTIMER Multi-Media system time

The default Clock Source is 0:SOFTWARE_CONVERT

error in (no error) Error in describes error conditions occurring before this VI executes.
This cluster defaults to no error.

Device Handle out Device Handle out contains the value of Device Handle in.

error out Error out contains error information. If the error in cluster indicated an error,
the error out cluster contains the same information. Otherwise, error out describes the
error status of this VI.
