Using Marker Delta Mode and Marker Minimum Search
/************************************************************/
/* Using Marker Delta Mode and Marker Minimum Search */
/* */
/* This example is for the N9322C Spectrum Analyzers */
/* */
/* This C programming example does the following. */
/* The SCPI instrument commands used are given as reference. */
/* */
/* - Opens a USB session */
/* - Clears the Analyzer */
/* - Resets the Analyzer */
/* *RST */
/* - Set the input port to the 50 MHz amplitude reference */
/* CAL:SOUR:STAT ON */
/* - Set the analyzer to single sweep mode */
/* INIT:CONT 0 */
/* - Prompts the user for the start and stop frequencies */
/* - Sets the start and stop frequencies */
/* SENS:FREQ:START freq */
/* SENS:FREQ:STOP freq */
/* - Trigger a sweep and delay for sweep completion */
/* INIT:IMM */
/* - Set the marker to the maximum peak */
/* CALC:MARK:MAX */
/* - Set the analyzer to activate the delta marker */
/* CALC:MARK:MODE DELT */
/* - Trigger a sweep and delay for sweep completion */
/* INIT:IMM */
/* - Set the marker to the minimum amplitude search mode */
/* CALC:MARK:PEAK:SEAR:MODE MIN */
/* - Set the marker to the minimum peak */
/* CALC:MARK:MAX */
/* - Query and read the marker amplitude */
/* CALC:MARK:Y? */
/* - Close the session */
