Web• If a signal has many frequency elements, the analysis is difficult. Frequency Domain • Each element of a complex signal can be separated easily. • Low-level distortion signals can be detected. • Spurious elements can be measured. Modulation Domain • Changes in frequency can be seen. • The modulation accuracy can be analyzed. WebTo measure the low-level signal, the spectrum analyzer’s sensitivity must be improved by minimizing the input attenuator, narrowing down the resolution bandwidth (RBW) fil- ter, and using a preamplifier. These techniques effectively lower the displayed average noise level (DANL), revealing the low-level signal. Figure 9. Noise obscuring the signal
