新型頻率計數器
B&K Precision 1820B Portable Bench Universal Frequency Counters are designed for versatile frequency measurements and provide exceptional stability and accuracy. These frequency counters feature a 0.5-inch LCD for displaying frequency, period, ratio, pulse width, and event counting measurements. The 1823B model measures frequencies up to 3GHz, while the 1826B model measures frequencies up to 6GHz. The 1820B universal frequency counters feature multiple input channels for precise measurements across a broad range of frequencies. These frequency counters offer ±1ppm time base stability and 100s, 10s, 1s, and 0.3s selectable measurement time. Input A setting offers flexible signal conditioning with configurable coupling (AC or DC), input impedance, attenuation, threshold (fully variable), and active edge. Typical applications include the verification and validation of oscillators and the manufacturing of electronic components.
