Wayne Kerr AMM20002Q Automatic Modulation Meter 150KHz-2.4GHz Farnell 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. The meter can also be used as a frequency counter. Resolutions of 10 Hz an 0.1 Hz can be expected over the RF and AF ranges respectfully. A rear panel AF input jack enables baseband signals for level and frequency to be analyzed. A TCXO reference is fitted as a standard with an aging rate of ±E-6 per year. Maximum sensitivity for modulation and frequency measurement is 30 dBm. Carrier levels can be measured in dBm or mW over a range of 6 dBm to +20 dBm. Carrier levels up to +30 dBm can be measured using an external 10 dB attenuator pad (maximum continuous power 1 W). Excess power protection is provided at the instrument RF input for signals up to 25 W and down to 250 mW. Manual operation of the meter is performed using the keyboard. The keyboard is a sealed tactile membrane front panel with an RFI shield laminated in it. The internal RAM can store 99 user defined setups. This RAM also allows rapid switching between predetermined tests. Individual memories are available for recall, store, and protect. All measurements are shown on a highly visible 32-character alphanumeric LED. A 20-segment analog LED bar graph is useful when viewing peaks and trends. Remote control operations are available through a GPIB interface. It can put settings and output measurements. This is ideal for use in automatic test systems. THE GPIB/HPIB connector is bent (refer to pictures). I never needed this when I used this unit.  GREAT UNIT! Comes from a working environment! EASY TO USE! Subject to prior sale!
