Measuring Spread Spectrum and Multitone Signals

Multitone Signal Measurements

In addition to wide dynamic range, the HP E-series E9300 power sensors also have an exceptionally flat calibration factor versus frequency response across the entire frequency range as shown in Figure 8. This is ideal for amplifier intermodulation distortion measurements where the components of the two-tone or multitone test signal can be separated by hundreds of MHz.
