4‑8GHz Multi‑Mode RF Digital Noise Source RS422 Control

This high‑performance rf digital noise source acts as a flexible signal generator covering 4‑8GHz working band. This 4‑8ghz noise source provides one output channel with 1MHz minimum frequency step, supporting instantaneous bandwidth options of 10MHz‑300MHz. It can produce linear sweep, CW, Gaussian white noise and comb‑spectrum integrated signals. The output power adjustment range reaches 30dB with 2dB step. Max output power is 5dBm±2dB for linear sweep and CW mode, while Gaussian white noise output achieves ≥0dBm. Excellent spurious rejection ≥45dBc and harmonic rejection ≥25dBc guarantee high‑quality signal output. This rf digital noise source adopts SMA output connector and RS422 control interface, powered by +12V power supply ≤0.6A. It stably operates from‑40℃ to +85℃. As a dependable signal generator, the compact 4‑8ghz noise source is widely applied in RF lab testing, signal simulation and wireless device debugging tasks.
