Rigol DG1022 function generator.

The Rigol DG1022 2-channel random function generators are affordable but very capable function generators.
Programmable via USB with the UltraWave software, simple specific signals can be sent via the 14-bit primary channel. Moreover, there is not yet a 10-bit secondary channel whose phase can be synchronized with the primary channel. With the help of Direct Digital Synthesis, the 1022 delivers reliable and precise signals. The simple and clear interface makes it easy to get started with the function generators.


The difference between the two models is in the bandwidth, furthermore these function generators are identical.
