Entering Amplitude Correction Data
/************************************************************/
/* Entering Amplitude Correction Data */
/* */
/* 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 */
/* - Resets the Analyzer */
/* *RST */
/* - Sets the stop frequency to 1.5 GHz */
/* SENS:FREQ:STOP 1.5 GHZ */
/* - Set the input port to the 50 MHz amplitude reference */
/* CAL:SOUR:STAT ON */
/* - Enter amplitude correction frequency/amplitude pairs: */
/* 0 Hz/ 0 dB, 100 MHz/5 dB, 1 GHz/-5 dB, 1.5 GHz/ 10 dB */
/* SENS:CORR:CSET1:DATA 0,0,100E6,5.0,1.0E9,-5.0,... */
/* - Activate amplitude correction */
/* SENS:CORR:CSET1:DATA */
/* SENS:CORR:CSET1:ALL:STAT ON */
/* - Query the analyzer for the amplitude corection factors */
/* SENS:CORR:CSET1:DATA? */
/* - Store them in an array */
/* - Display the array */
/* - Close the session */
