Power Spectrum (FFT)
With the spectrum display, the signal spectrum is calculated from the I/Q signal by means
of Fourier Transform (FFT). The power density over frequency is displayed. The power
density is plotted on the Y axis, and frequency is plotted symmetrically on the X axis (-
sampling rate/2 to +sampling rate/2). FFT Points indicates the number of I/Q value pairs
which are used for calculating a (part-)FFT. AVG indicates number of subspectra used
for averaging. The recording depth is 8 kSamples.
The spectrum display of the output signal is particularly suitable for checking multi carrier
signals.
