MFP-800 Frequency Power Meter

MFP-8000 can be used to measure frequency and power of radio signals in a wide range of development, diagnostic, adjustment and search applications related to radio devices.

Specialists are familiar with manual field indicators of MFP series used for these purposes with an option of measuring frequency. These handheld devices have worked reliably during many years, the latest from them is MFP-3.

A portable signal power and frequency meter is designed for measuring frequency and intensity of radio signals in broadband in field environment, which often takes place at the practical impossibility of galvanic connection to the measured radio signal source.

Operating principle  The operating principle of the portable frequency meter represents a broadband field indicator extracting signal that is maximum at the measured point of space. The portable signal power and frequency meter can be used when adjusting radio transmitting equipments, monitoring air and searching for tacitly installed radio communication units.

MFP-8000, developed on the basis of the latest advances in the RF components and technology and vast engineering and operating experience incorporates the best properties and features of MFP instruments.

MFP-8000 can detect any sources of radio emission within the frequency range from 100 kHz up to 8GHz featuring sensitivity of -53dBm with a typical S/N ration of 5dB.  That means that a transmitting device with an output power of +7dBm (5mW) coupled to a matched 1/4 wavelength antenna can be easily detected from the distance of up to 8m.

MFP-8000 has the following features: 

  • 30dB input attenuator adjusted in 10dB steps.
  • Count time selection.
  • Input frequency range selection.
  • User level correction setting.
  • Battery charge/discharge control
  • Real-time clock and calendar.
  • Built-in light and acoustic indication.
  • RS-232 interface.
