Module_HP8568B (ul_pbar_instruments)

 *  Module intent:
 *    Module HP8568B provides a high-level C language interface to the Hewlett
 *    Packard model HP8568B spectrum analyzer.  The HP8568B routines handle all
 *    details of the GPIB communications and provide a programmer interface that
 *    presents the spectrum analyzer in the way that an engineer might imagine.
 *    Routines are provided for setup of many 'generic spectrum analyzer'
 *    parameters including:
 *	HP8568B__Initialize()		Select and Initialize spectrum analyzer
 *	HP8568B__GetStatus()		Return HP8568B status registers
 *	HP8568B__ReportStatus()		Print HP8568B status errors
 *    Prototypes for these routines and the associated data types and constants
 *    are contained in the ul_pbar_instruments:hp8568b.h header file.
