Reading Trace Data Using 32-bit

Real Format (HP-IB)

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

/* Reading Trace Data using 32-bit Real Format (HP-IB)

/*
/* This C programming example does the following.
/* The SCPI instrument commands used are given as
/* reference.
/*
/* - Opens an HP-IB session at address 18
/* - 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?
/* - Calculate the number of bytes in the header
/* - 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
/* - Specify 10 dB per division for the amplitude scale in
/* and dBm Units
/* DISP:WIND:TRAC:Y:SCAL:PDIV 10 dB
/* UNIT:POW DBM
/* - Set the analyzer trace data to 32-bit Real
/* FORM:DATA: REAL,32
/* - Set the binary order to swap
/* FORM:BORD SWAP
/* - Trigger a sweep
/* INIT:IMM
/* - Check for operation complete
/* *OPC?
/* - Calculate the number of bytes in the trace record
/* - Query the trace data
/* TRAC:DATA? TRACE1
/* - Remove the "," from the ACSII data
/* - Save the trace data to an ASCII file
/* - Close the session
