Status Register–Determine When a Measurement is

Done

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

/* Status Register - Determine when a measurement is done		*/
/*		*/
/* 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		*/
/* - Resets the Analyzer		*/
/*	*RST	*/
/* - Clears the analyzer status byte		*/
/*	*CLS	*/
/* - Sets the analyzer to single sweep mode		*/
/*	INIT:CONT 0	*/
/* - Route the amplitude reference to the analyzer input		*/
/*	CAL:SOUR:STAT ON	*/
/* - Set the analyzer center frequency, span and Res BW		*/
/*	SENS:FREQ:CENT 50 MHz	*/
/*	SENS:FREQ:SPAN 10 MHz	*/
/*	SENS:BAND:RES 300 kHz	*/
/* - Trigger a sweep and wait for completion of sweep		*/
/*	INIT:IMM	*/
/*	*OPC?	*/
/* - Sets the service request mask to assert SRQ when		*/
/*	either a measurement is uncalibrated or an error	*/
/*	message has occurred.	*/
/*	*SRE 96	*/
/*	*ESE 35	*/
/* - Set the computer to response to an interrupt		*/
/* - Send an undefined command to the ESA		*/
/*	IDN (illegal command)	*/
/* - Wait for the SRQ		*/
/* - When an interrupt occurs, poll all instruments		*/

/* - Report the nature of the interrupt on the ESA analyzer */

/* - Pause 5 seconds to observe the analyzer		*/
/* - Set the ESA to perform 80 video averages		*/
/*	SENS:AVER:TYPE LPOW	*/
/*	SENS:AVER:COUN 80	*/
