The B&K Model 1856D provides versatility and reliability for a broad range of laboratory and service applications to 3.5 GHz.
This reciprocal Frequency Counter is a microprocessor-controlled instrument for frequency measurement. 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).
