6GHz Compact Signal Generator R19


SKU: N/A Category:


The DS Instruments SG6000L ultra-compact RF Signal Generator continues to set the industry standard in affordable and portable RF Signal Generation. The SG6000L enables users to generate a high quality RF signal easily and at extremely low cost without need for a host PC. This fully synthesized, modern fractional N synthesis device covers 7 octaves from 24 to 6000 MHz. Max output power is typically above +15 dBm and can be adjusted downward in 0.5dB steps, or continuously via the internal variable attenuator. The RF output step size varies from a maximum of ~3 KHz to less than 40 Hz, depending on band of operation. The crisp OLED display provides useful feedback for the user, and front control buttons provide a quick alternative to USB control. Like most of our products, the SG6000L easily fits in the palm of your hand, making it a truly portable and bench-space-saving device.
