Product Overview

BK1823B is a 1820B series universal frequency counter. It is a compact instrument designed for versatile frequency measurements. Featuring a clear 0.5" LCD, these counters measure a wide frequency range, from 0.001Hz to 3GHz and support frequency, period, ratio, pulse width, and event counting measurements. Equipped with a high-quality temperature-compensated internal frequency reference, these counters provide exceptional stability and accuracy, with a low aging rate of ±1ppm across the entire temperature range. Multiple input channels allow for precise measurements across a broad spectrum of frequencies. Input A offers flexible signal conditioning, with configurable coupling (AC or DC), input impedance (1Mohm or 50 ohm), attenuation (1:1 or 5:1), threshold (fully variable) and active edge. For frequency, period, and ratio functions the instrument uses a reciprocal counting technique to provide high resolution at all frequencies.
