The Siglent SDG2122X is a 2 channel Function / Arbitrary Waveform Generator to create high quality signals up to 120 MHz (Sine). Beside the analog output, the device includes an USB-Host, an USB-device and a LAN interface.
The Siglent function generators have a sophisticated and easy to use interface and offer multiple functions for all tasks. The menu navigation is very intuitive and all functions and parameters are easy to locate thanks to the graphical touch interface.
