The model DG1022Z features 2 fully-fledged and independent output channels (with the same specifications) as well as an internal memory of 8 Mpts. In addition to typical standard functions, it integrates over 160 arbitrary signals such as ECG, Gaussian curves, Lorentz, dual tone, and exponential rise and fall. It offers the highest signal quality of 1 ppm at 14-bit resolution.
