1826B

1826B is a 1820B series universal frequency counter. It is a compact instrument designed for versatile frequency measurements. Featuring a clear 0.5" LCD, this counter measures a wide frequency range, from 0.001Hz to 6GHz and support frequency, period, ratio, pulse width, and event counting measurements. Equipped with a high-quality temperature-compensated internal frequency reference, this counter provides 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/DC), input impedance (1Mohm/50 ohm), attenuation (1:1/5:1), threshold and active edge. With the 1826B, an additional input C offers an N-type connector with 50 ohm input impedance and frequency range of 2GHz to 6GHz.
