Description

The recently updated DS Instruments SG12000L compact Microwave Signal Generator enables users to generate a high-quality RF signal easily and at low cost. The output covers the entire 50 – 13000MHz frequency block. This produced output waveform is fully synthesized using modern fractional-N synthesis. The frequency step size is only 2Hz in all bands as of REV 18. The synthesized source can accept an external 10 MHz reference, or it can use its own internal 10 MHz TCXO. Output power is calibrated between -25 and +14dBm, and can be set in 0.5dB steps over the entire frequency range. The crisp OLED display provides useful feedback for the user, and front control buttons provide a quick alternative to USB control. Ethernet is now standard, and full-band RF power control is calibrated to under ±1.0dB. Like most of our products, the SG12000L easily fits in the palm of your hand, making it a truly portable and bench-space-saving device.

New REV18 with lowered phase-noise, smaller step-size, and phase control shipping as of 2026!
