1820B Frequency Counter Series With 10 Digits of Resolution
The 1820B Series Universal Frequency Counters are compact instruments designed for a wide range of frequency measurement applications, from telecommunications to the verification and validation of oscillators.
The series features a clear 0.5-inch 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 s of measurement time, 9 digits in 10 s, and 10 digits in 100 s.
Equipped with a high-quality temperature-compensated internal frequency reference, the 1820B Series provides 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 h on internal battery power.
