Low-Harmonic RF Generator


SKU: SG6000F Category:


The DS Instruments SG6000F RF Signal Generator continues to set the industry standard in affordable ultra-compact RF Signal Generation. The SG6000F provides a pure low-harmonic sine-wave, unlike most other compact signal generators. This fully synthesized, modern fractional-N device covers up to 6GHz. Output power is calibrated from -20 to +10dBm, and can be adjusted downward in 0.5dB steps, or continuously via the internal variable attenuator. The bright OLED display provides useful feedback for the user, and front control buttons provide a quick alternative to USB control. In applications where low signal distortion is critical, the SG6000F or the low-phase-noise SG6000PRO are unbeatable solutions.
