/************************************************************/

/* Performing Internal Self-alignment	*/
/*	*/
/* This example is for the E44xxB ESA Spectrum Analyzers	*/
/* and E740xA EMC Analyzers.	*/
/*	*/
/* 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 are given as		*/
/* reference.		*/
/*		*/
/* - Opens a GPIB 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		*/
