/* This C programming example does the following:
/* Performs Power Averaging of Multiple ESA Measurements
/* and Writes the Result back to a Trace for display
/*
/* The required SCPI instrument commands are given as
/* reference.
/*
/* - Opens a GPIB device at address 18
/* - Clears and Resets the Analyzer to a known state
/*
SYST:PRES:TYPE FACT
/*
*RST
/* - Identify the Instrument model
/*
*IDN?
/* - Sets the analyzer center frequency and span
/*
SENS:FREQ:CENT freq
/*
SENS:FREQ:SPAN freq
/* - Sets the analyzer resolution bandwidth
/*
SENS:BAND rbw
/* - Selects sampled as the detector mode
/*
SENS:DET SAMP
/* - Disable optional Input/Output functions
:
/*
SYST:PORT:IFVS:ENAB OFF
/* - Turn off auto-alignment
/*
CAL:AUTO OFF
/* - Select the desired number of sweep points
/*
SWE:POINTS points
/* - Select the appropriate display reference level and
/*
amplitude reference routing
