(RS-232)
/************************************************************/

/* Reading Trace Data using ASCII Format (RS-232)

/*
/* This C programming example does the following.
/* The SCPI instrument commands used are given as
/* reference.
/*
/* - Opens an RS-232 session at COM1/COM2
/* - Clears the Analyzer
/* - Resets the Analyzer
/* *RST
/* - Set the input port to the 50 MHz amplitude reference
/* CAL:SOUR:STAT ON
/* - Query for the number of sweep points (for firmware
/* revisions A.04.00 and later). Default is 401.
/* SENS:SWE:POIN?
/* - Set the analyzer to single sweep mode
/* INIT:CONT 0
/* - Sets the analyzer center frequency and span to 50 MHz
/* SENS:FREQ:CENT 50 MHZ
/* SENS:FREQ:SPAN 50 MHZ
/* - Trigger a sweep
/* INIT:IMM
/* - Check for operation complete
/* *OPC?
/* - Specify dBm Unit
/* UNIT:POW DBM
/* - Set the analyzer trace data ASCII
/* FORM:DATA: ASC
/* - Trigger a sweep
/* INIT:IMM
/* - Check for operation complete
/* *OPC?
/* - Query the trace data
/* TRAC:DATA? TRACE1
/* - Remove the "," from the ACSII data
/* - Save the trace data to an ASCII file
/* - Close the session
