Normalize
Before you perform a two port insertion loss measurement, you must first normalize the
measured values for insertion loss by compensating for the loss associated with the devices
(adapters, cables) that connect the Agilent CSA Spectrum Analyzer to the device or
assembly being tested. Otherwise, the loss introduced by these connecting devices is added
to the loss of the device under test.

You cannot set the Start frequency equal to the Stop frequency.
The instrument will alter the value of the last setting to
maintain a minimum value of 1 kHz difference between the
Start and Stop frequencies.
