Functions listed alphabetically
age1439_vcxo
Selects whether the internal clock source in the module is turned on or off. This description also
includes the query function:
age1439_vcxo_get
VXIplug&play Syntax
#include "age1439".h
ViStatus age1439_vcxo(ViSession id,ViInt16vcxoState);
ViStatus age1439_vcxo_get(ViSession id,ViPInt16vcxoStatePtr);
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 whether the internal clock source is turned on or off.
Note This function is ignored in IF path since the Agilent E1439D does not run in IF mode if the
VCXO is turned off. If you switch from baseband to IF path the VCXO turns on; it remains on if
you switch back to baseband.
Parameters
id is the VXI instrument session pointer returned by the age1439_init function.
vcxoState AGE1439_VCXO_OFF specifies that the internal clock source is turned off.
AGE1439_VCXO_ON that the internal source is turned on.
vcxoStatePtr Returns a pointer to the actual state of the VCXO.
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
page 102.
