Equipment Calibration
Refer to Figure K14 to calibrate the test equipment.
• Perform “Equipment Set-Up”.
• Connect the test cable from the “RF Output” of the Signal Generator to the
“RF input” of the Spectrum Analyzer.
• Turn on the RF output of the Signal Generator.
• Perform a “peak search” on the Spectrum Analyzer.
• Set a Delta point. The Delta sets a zero point on the Spectrum Analyzer so that
when any additional cable or equipment is added to the link the new loss
reading can be recorded. (Note: If the Spectrum Analyzer does not have a
Delta function, increase the output of the Signal Generator until there is a 0
dB reading on the Spectrum Analyzer.)
