Rigol DG3121A Waveform Generator


Quick Overview

High quality function / arbitrary waveform generator with 120 MHz bandwidth, 300 MSa/s and 1 Mpts memory. 


Product Description

The Rigol DG3121A is a Function / Arbitary Waveform Generator to create high quality signals up to 120 MHz (Sine). Beside the analog output the devices include a USB-Host- and a USB-device, a RS-232, LAN and GPIB interface.

The Rigol Function-generators have a sophisticated and easy to use userinterface and offers multiple functions for all tasks. The menu navigation is very intuitional in use and all functions and parameters are easy to reach because of the graphical interface.


Special Features


Filesystem and USB Stick Support

The devices have a filesystem for the storage of waveforms in the internal memory or on USB sticks.


Integrated Helpsystem

The integrated helpfunction will show descriptions of single functions and step-by-step instructions for often used tasks.
