Signal Analysis
The analysis of electrical signals is a fundamental problem for many engineers and
scientists. Even if the immediate problem is not electrical, the basic parameters of
interest are often changed into electrical signals by means of transducers. Under
this option, there are:
– Channel Power.
– Occupied BW (Bandwidth).
Channel Power
The channel power measurement is made on the RF input signal after frequency
down conversion and an analog to digital conversion. The actual power
measurement is performed by the test set's digital signal processor (DSP).
