  • Page 35: Multitone Signal Measurements

    Making Measurements Multitone Signal Measurements In addition to wide dynamic range, the Keysight E-Series E9300 power sensors also have an exceptionally flat calibration factor versus frequency response across the entire frequency range as shown in Figure 2-5. 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.

  • Page 36: Measuring Tdma Signals

    Making Measurements Measuring TDMA Signals Power meter and sensor operation The voltages generated by the diode detectors in the power sensor can be very small. Gain and signal conditioning are required to allow accurate measurement. This is achieved using a 220 Hz (440 Hz in fast mode) square wave output from the power meter to drive a chopper-amplifier in the power sensor.
