/*********************************************************************
*     SerAlign.c	
*     Serial Poll Alignment Routine
*     Agilent Technologies 2001
*	
*     Instrument Requirements:
*        PSA Series Spectrum Analyzer or
*        ESA Series Spectrum Analyers or
*        VSA Series Transmitter Tester
*
*   This program demonstrates how to
*   1) Perform an instrument alignment.
*   2) Poll the instrument to determine when the operation is complete.
*   3) Query to determine if the alignment was successfuly completed.
