Determine if an Error has Occurred
/************************************************************/
/* Determine if an error has occurred
/*
/* 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 service request mask to assert SRQ when
/*
either a measurement is uncalibrated or an error
/*
message has occurred.
/*
STAT:QUES:ENAB 512
/*
STAT:QUES:INT:ENAB 8
/*
*ESE 35
/*
*SRE 104
/* - Set the center frequency to 500MHz and span to 100MHz
/*
SENS:FREQ:CENT 500 MHZ
/*
SENS:FREQ:SPAN 100 MHZ
/* - Set the analyzer to an uncalibrated state
/* - When an interrupt occurs, poll all instruments
/* - Report the nature of the interrupt on the ESA analyzer */
/* - Pause 5 seconds to observe the analyzer
/* - Sets the service request mask to assert SRQ when
/*
either a measurement is uncalibrated or an error
/*
message has occurred.
/*
*ESE 35
/*
*SRE 96
/* - Send an illegal command to the ESA
/*
IDN
(illegal command)
/* - When an interrupt occurs, poll all instruments
/* - Report the nature of the interrupt on the ESA analyzer */
/* - Clear the analyzer status registers
