B&K Precision, a leading designer and manufacturer of reliable, cost-effective test and measurement instruments has introduced its new Series 1820B Universal Frequency Counters. The compact and versatile instruments are designed for a wide range of frequency measurement applications, from telecommunications to verification and validation of oscillators.
B&K Precision’s new Frequency Counter 1820B Series is available from Comtest.
The 1820B Series features a clear 0.5" LCD and support for frequency, period, ratio, pulse width, and event counting measurements. The 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 eight significant digits in one second of measurement time, nine digits in 10 seconds, and 10 digits in 100 seconds.
Equipped with a high-quality temperature-compensated internal frequency reference, the 1820B Series provides a high level of stability and accuracy, with a low aging rate of ±1 ppm across the 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.
B&K Precision 1820B Universal Frequency Counters are available locally from Comtest.
