/* Using Marker Peak Search and Peak Excursion

/*
/* This C programming example does the following.
/* The SCPI instrument commands used are given as
/* reference.
/*
/* - Opens an HP-IB session at address 18
/* - Clears the Analyzer
/* *CLS
/* - Resets the Analyzer
/* *RST
/* - Sets the analyzer center frequency and span
/* SENS:FREQ:CENT freq
/* SENS:FREQ:SPAN freq
/* - Set the input port to the 50 MHz amplitude reference
/* CAL:SOUR:STAT ON
/* - Set the analyzer to single sweep mode
/* INIT:CONT 0
/* - Prompt the user for peak excursion and set them
/* CALC:MARK:PEAK:EXC dB
/* - Set the peak threshold to -90 dBm
/* TRAC:MATH:PEAK:THR:STAT ON
/* TRAC:MATH:PEAK:THR -90
/* - Trigger a sweep
/* INIT:IMM
/* - Check for operation complete
/* *OPC?
/* - Set the marker to the maximum peak
/* CALC:MARK:MAX
/* - Query and read the marker frequency and amplitude
/* CALC:MARK:X?
/* CALC:MARK:Y?
/* - Close the session
