AGC Experiment: spectrogram. To show the influence of the AGC, a power varying test signal is fed to the receiver input; the spectrogram shows the AGC influence (field strengths in dBm/Hz). The input signal increases in power over time (traces) and is visible by the stepwise square-shaped signals in the spectrogram. The noise level lifts up which results in wide-band artifacts in the spectrogram. In addition, the specification of the input signal power levels are listed in TableĀ 1.
