/************************************************************ /
/* Performing Internal Self-alignmen t
/ *
/* 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 ha s
/* 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 an HP-IB session at address 1 8
/* - Clears the Analyze r
/* *CL S
/* -
Resets the Analyzer
/* *RST
/* - VISA function sets the time out to infinit e
/* - Initiate self-alignmen t
/* CAL :ALL
/* - Query for operation complet e
/* *OPC?
/* - Query for results of self-alignment
/* CAL :ALL ?
/* - Report the results of the self-alignmen t
/* - Close the session
