Entering Amplitude Correction Data

Entering Amplitude Correction Data
This C programming example does the following:
• Open an HP-IB session at address 18.
• Clear the analyzer.
• Reset the analyzer.
• Set the analyzer stop frequency to 1.5 GHz.
• Set the input port to the 50 MHz amplitude reference.
• Enter amplitude correction frequency/amplitude
pairs:100 MHz/5 dB, 1 GHz/−5 dB, 1.5MHz/10 dB.
• Activate amplitude correction.
• Store the array (frequency, amplitude) value into a two-dimensional
real array.
• Query the analyzer for the amplitude correction factors.
• Remove the "," token from the amplitude correction for analyzing
data.
• Display the contents of the array.
• Close the session.
