RIGOL DSG821-OCXO: Precision RF Signal Generation from 9kHz to 2.1GHz

RIGOL DSG821-OCXO: Precision RF Signal Generation from 9kHz to 2.1GHz .

Product Overview:

The RIGOL DSG821-OCXO RF Signal Generator is a compact benchtop instrument tailored for precise signal testing in wireless communications, RF engineering, aerospace, and defense industries. With a wide frequency range of 9 kHz to 2.1 GHz, excellent phase noise performance of <-112 dBc/Hz, and <0.5 dB amplitude accuracy, it provides high-fidelity signals essential for critical validation tasks.

This model comes equipped with OCXO-B08 high-stability timebase, offering frequency stability of <5 ppb, making it highly suitable for long-duration and phase-sensitive testing environments. Engineers benefit from its high output power (up to +20 dBm) and flexible modulation types such as AM, FM, PM, CW, without the need for external amplifiers.
