Performing Internal Self-alignment

/************************************************************/
/* Performing Internal Self-alignment
/*
/* This example shows two ways of executing an internal
/* self-alignment. The first demonstrates using the *OPC?
/* query to determine when the alignment has completed. The */
/* second demonstrates using the query form of the CAL:ALL
/* command to not only determine when the alignment has
/* been completed, but the pass/fail status of the align-
/* ment process.
/*
/* This C programming example does the following.
/* The SCPI instrument commands used
/* reference.
/*
/* - Opens an HP-IB session at address 18
/* - Clears the Analyzer
/* *CLS
/* - Resets the Analyzer
/* *RST
/* - VISA function sets the time out to infinite
/* - Initiate self-alignment
/* CAL:ALL
/* - Query for operation complete
/* *OPC?
/* - Query for results of self-alignment
/* CAL:ALL?
/* - Report the results of the self-alignment
/* - Close the session
