SG22000PRO Low-Noise Generator


SKU: SG22000PRO Category:


An ultra-compact low-noise 100MHz to 22GHz microwave signal generator.

After years of development DS Instrument’s updated low-noise premium signal generator has been released! Offering lower phase noise, a wider frequency range, and more robust output level control than the standard SG22000. Like our SG6000 product line, this RF generator is fully programmable via SCPI commands (USB / Ethernet) or the front panel interface making it more flexible than any competing product. Offered as a higher performance version of the SG22000L, this upgraded microwave generator is aimed at phase-noise sensitive applications in X, Ku, and K-band development and testing.

Now shipping 2024 hardware version with additional harmonic filtering!
