BK182xB frequency counters

B&K Precision’s new BK1820B Series Universal Frequency Counters are compact solutions designed for frequency and time interval measurements.

They hae a clear 0.5" 10-digit LCD, a wider frequency range up to 3 GHz (BK1823B) or 6 GHz (BK1826B) and improved time base stability of ±1 ppm. Supported measurement functions include frequency, period, ratio, pulse width, and event counting.

The BK1820B Series provides multiple input channels allowing for precise measurements across a broad spectrum of frequencies. Input A measures from 1 mHz to 125 MHz and offers flexible signal conditioning 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 extends the input range from 80 MHz to 3 GHz range with a 50 Ω output. The BK1826B features an additional input C, a dedicated microwave channel with an N-type connector. The series also includes a USB (VCOM) interface, enabling remote control and automatic power supply from a computer. Both models can be powered with the included AC adaptor or for 24 hours on internal rechargeable batteries. Priced from only 540 €, the BK1820B Series is ideal for applications in electronic component manufacturing and verification and validation of oscillators.
