The Modulation Meter AMM20002Q is a portable full featured modulation meter. It measures signals in the 150 kHz to 2.4 GHz frequency range. This range covers virtually all radio services in MF, HF, VHF, und UHF bands. A microprocessor automatically locks onto the strongest carrier frequency. The keyboard is used for manual tuning.
A built-in digital self-calibration source is used for AM, FM, and PM measurements. An accuracy of better than 1% is achieved using the built-in digital self-calibration source. The modulation bandwidth is 10 Hz to 300 kHz. This allows for measurements on high data rate systems. Modulation measurement capability is 99% AM, 500 kHz pk FM, and 50 rad PM. The large FM deviation is useful when measuring wideband telemetry systems.
The modulation meter has a low noise figure. This maximizes the resolution for narrowband and unwanted modulation measurements. The meter is equipped with three high pass and four low pass filters, an FM de-emphasis mode, and peak or true RMS level modes. These features provide post carrier detection signal conditioning. The display can be set to give absolute or relative values. These values can either be linear or dB. Measurements with a peak hold are available for burst capture. When making residual noise measurements, digital averaging can be selected.
