ABCs of Modulation Domain Analysis Background An instrument like an Oscilloscope lets you view voltage variations over time. A Spectrum Analyzer lets you view voltage variations over frequency. A Modulation Domain Analyzer (MDA) lets you view frequency variations over time. Figure 1 shows all three dimensions pictorially. To analyze all dynamic properties of a signal‚ all three of these tools are required: Oscilloscope (v vs. t) Spectrum Analyzer (v vs. f) Modulation Domain Analyzer (f vs. t) While
