This compact frequency meter that can easily fit in your palm is designed to measure frequency and signal period. The use of a specialized microprocessor allows introducing a number of "smart" functions. Using the external telescopic antenna you can measure the carrier frequency of various radio transmitting devices.

Features:

  • High sensitivity for the VHF & UHF frequency measurement, excellent for CB hobbyist.
  • Handheld & pocket size instrument
  • Wide measuring range up to 2.6GHz
  • Good resolution, 0.1Hz min. display unit for 10MHz range.
  • Used the exclusive Microprocessor IC offered the intelligent function: Frequency, Period, Multi resolution, Data hold, Relative measurement, Data record (Max., Min., Average reading).
  • Auto power off & manual power off.
  • LCD display for low power consumption & clear read-out even in bright ambient light condition.
  • The instrument used the low PPM crystal time base to offer high accuracy measurement.
  • The optional telescoping antenna accessory can be used to pick up transmit frequencies from handheld, fixed or mobile radios such as: POLICES, FIRE FIGHTER'S, HAM, TAXI, AIRCRAFT MARINE, etc. at ranges of approaching 5 to 30 cm (depending on transmitter power, antenna obstructions, etc.).

Este medidor de frecuencia compacto que cabe fcilmente en la palma de su mano est diseado para medir la frecuencia y el perodo de la seal. El uso de un microprocesador especializado permite introducir una serie de funciones "inteligentes". La antena externa telescpica permite medir la frecuencia de la portadora de diversos dispositivos de radio transmisin.

Caractersticas:

  • Alta sensibilidad de la medicin de la frecuencia VHF y UHF, excelente para aficionados CB.
  • Instrumento manuable que cabe en un bolsillo
  • Amplio rango de medicin de hasta 2.6GHz
  • Buena resolucin 0.1Hz min. display unit for 10MHz range.
  • Uso de microprocesador exclusivo IC con funcin inteligente: Frecuencia, Perodo, resolucin mltiple, retencin de datos, medicin relativa, registro de datos, mximo, mnimo y promedio de lectura.
  • Apagado automtico y manual.
  • Pantalla LCD de bajo consumo de energa, clara lectura incluso en condiciones de luz brillante.
  • El instrumento utilizada un cristal PPM de bajo temporizador para ofrecer una medicin de alta precisin.
  • La antena telescpica (accesorio opcional) se puede utilizar para captar frecuencias de transmisin de radios porttiles, fijos o mviles, tales como: La Policia, Los Bomberos, Taxistas, Marina y otros servicios de comunicaciones. Al acercarse al transmisor (3 a 30 cm) o en dependencia de la potencia de este pueden ocurrir obstrucciones de la antena, la recepcion etc.)
