getstatus
This command returns various parameters pertaining to the state of the 4210-CVU.
Usage
int getstatus(int instr_id, long parameter, double *value);
The instrument identification code of the 4210-CVU:
Parameter to be queried; the macros for the KI_CVU parameters are defined in
Returned value for the queried parameter
Details
Parameter: Returns:
