SG40000L Signal Generator 40GHz

Introducing the SG40000L, our latest portable and affordable high-frequency signal generator!

DS Instrument’s new high-frequency microwave signal generator has been released! This new standard version offers the same low-noise performance of the SG30000L, but with a higher frequency band covering 25to 40GHz . Like our SG6000 product line, this source is fully programmable via SCPI commands, or the front panel interface, making it more flexible than any competing product. High output power, wide bandwidth, and ultra-compact size make this the best value 40GHz source on the market.

2023 REV 6 hardware now shipping with reduced sub-harmonic levels!
