/* 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. */
/* */
/* */
/* - Open a GPIB session at address 18. */
/* - Clear the analyzer. */
/* *CLR */
/* - Reset the analyzer. */
/* *RST */
/* - Set Y-Axis Units to dBm */
/* UNIT:POW DBM */
/* - Define the upper limit line to have frequency/ */
/* amplitude pairs. */
/* CALC:LLINE1:CONT:DOM FREQ */
/* CALC:LLINE1:TYPE UPP */
/* CALC:LLINE1:DISP ON */
/* CALC:LLINE1:DATA freq1,amp1,1,freq2,amp2,1... */
/* - Define the lower limit line to have frequency/amplitude*/
/* pairs. */
/* CALC:LLINE2:CONT:DOM FREQ */
/* CALC:LLINE2:TYPE LOW */
/* CALC:LLINE2:DISP ON */
/* CALC:LLINE2:DATA freq1,amp1,1,freq2,amp2,1... */
/* - Turn the limit line test function on. */
/* CALC:LLINE2:STAT ON */
/* - Set the analyzer to a center frequency of 50 MHz, span */
/* to 20 MHz, and resolution bandwidth to 1 MHz. */
/* SENS:FREQ:SPAN 20 MHZ */
/* SENS:FREQ:CENT 50 MHZ */
/* SENS:BWID:RES 1 MHZ */
/* - Turn the limit line test function on. */
/* - Set the analyzer reference level to 0 dBm. */
/* DISP:WIND:TRAC:Y:SCAL:RLEV 0 */
/* - Set the input port to the 50 MHz amplitude reference. */
/* CAL:SOUR:STAT ON */
