Equipment Calibration
Refer to Figure O14 to calibrate the test equipment.
Step 1. Perform “Equipment Set-Up”.
Step 2. Connect the test cable from the “RF Output” of the Signal Generator to the “RF input”
of the Spectrum Analyzer.
Step 3. Turn on the RF output of the Signal Generator.
Step 4. Perform a “peak search” on the Spectrum Analyzer.
Step 5. 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.)
