Due to uniquely developed LSI circuitry in an expanding/reciprocal system, high accuracy with 9-digit resolution is achieved with a one second gate time. It covers a frequency range of from 0.1 Hz to 3.5 GHz based on a 10 MHz TCO (Temperature Controlled Oscillator). Other features include: �¡ RPM (Revolutions Per Minute) Measuring Function �¡ External Frequency Standard Input with 9 Digit LED Display �¡ Attenuator �¡ Period �¡Total �¡ Low Pass Filter �¡ Line Filter �¡ RS-232 Interface Also provided is a self-test function for a quick check of several operating modes. Each mode can be selected by a front panel push button switch with automatic decimal points and indicators. The high accuracy, sensitivity and versatility of this counter make it an extremely valuable instrument to the scientist, engineer, experimenter and communications technician. Lightweight and compact size make it practical for use by the hobbyist or field technician. Specifications model 1856D
