Making the Output Spectrum Bandwidth Measurement

Purpose

The ouput spectrum bandwidth measurement is used to verify if the emissions
inside the operating frequency are within the limits.

Measurement Method

To perform this measurement the analyzer is tuned to the channel to be measured
and the span is set to 2 MHz. The peak of the current trace is identified. The
measurement then places markers at the points highest and lowest in frequency in
the current span where the signal drops −20dB from this peak value. The
frequency between these two points is measured as the output spectrum
bandwidth.
