B&K Precision New Frequency Counter 1820B Series

        Wide frequency range with 10 digits of resolution                                     

B&K Precision, a leading designer and manufacturer of reliable, cost-effective test and measurement instruments has a new Series 1820B Universal Frequency Counters. These compact and versatile instruments are designed for a wide range of frequency measurement applications, from telecommunications to verification and validation of oscillators.

The 1820B Series features a clear 0.5″ LCD and support for frequency, period, ratio, pulse width, and event counting measurements. This series uses a reciprocal counting technique to provide high resolution at all frequencies, from 1 mHz to 3 GHz (1823B) or 6 GHz (1826B). The counters deliver 8 significant digits in 1 second of measurement time, 9 digits in 10 seconds, and 10 digits in 100 seconds.

Equipped with a high-quality temperature-compensated internal frequency reference, the 1820B Series provides exceptional stability and accuracy, with a low aging rate of ±1 ppm across the entire temperature range. Input A offers flexible signal conditioning over DC to 125 MHz, with configurable coupling (AC or DC), input impedance (1 MΩ or 50 Ω), attenuation (1:1 or 5:1), threshold (fully variable) and active edge. Input B provides 50 Ω impedance from 80 MHz to 3 GHz. The 1826B also includes an additional input C with an N-type connector, 50 Ω input impedance, and a frequency range of 2 GHz to 6 GHz.

The 1820B Series provides a USB interface for remote control and powering the device via a computer. Additional powering options include continuous AC operation with the supplied AC charger or up to 24 hours on internal battery power.
