Status Register–Determine When a
Measurement is Done
/************************************************************/
/* Status Register - Determine when a measurement is done
/*
/* This C programming example does the following.
/* The SCPI instrument commands used are given as
/* reference.
/*
/* - Opens an HP-IB 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 32
/* *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
/* SENS:AVER:STAT ON
/* - Trigger a measurement, and set OPC bit when done
/* INIT:IMM
