SG4400L RF Signal Generator 4400MHz w/Ethernet

The DS Instruments SG4400L compact RF Signal Generator enables users to generate a high quality RF signal easily and at low cost. The output covers 35 to 4400 MHz. The produced wave is fully synthesized using modern fractional N synthesis. The step size of the RF output  varies from a maximum of ~1.5KHz to less than 25Hz , depending on band of operation. The synthesized source has its own internal precision 10 MHz reference frequency. Maximum output power is calibrated to +15dBm, and can be adjusted in 0.25dB steps down to -25dBm. 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 SG4400L easily fits in the palm of your hand, making it a truly portable and bench-space-saving device.
