Example:

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

/* Using Marker Peak Search and Peak Excursion		*/
/*		*/
/* This example is for the E44xxB ESA Spectrum Analyzers		*/
/* and E740xA EMC Analyzers.		*/
/*		*/
/* 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	*/
/* - Sets the analyzer center frequency, span and units		*/
/*	SENS:FREQ:CENT freq	*/
/*	SENS:FREQ:SPAN freq	*/
/*	UNIT:POW DBM	*/
/* - 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 and wait for sweep to complete		*/
/*	INIT:IMM;*WAI	*/
/* - 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		*/
