SU432X Series Noise Source is a high-performance measurement equipment essential for ensuring the working stability of facilities in communication systems. It generates Gauss white noise with a broadband standard, featuring uniform and controlled spectral density, and no DC or excess noise. The series, including models SU4323 and SU4326, utilizes the heat noise from the intermediate amplifier, which has the characteristics of Gauss white noise, as its noise source. With different noise bandwidths (10MHz ~ 3.0GHz for SU4323 and 10MHz ~ 6.0GHz for SU4326), an attenuation range of 0.0~60.0dB with a 0.1dB step, and a maximum output noise of ≥3.0dBm within their respective bandwidths, it offers reliable performance. It also comes with interfaces like RS-232, USB (standard), and optional GPIB, making it adaptable to various working environments.
