APPLICOS AWG22 Module

A 22 bit Arbitrary Waveform Generator for medium-speed / high resolution waveform generation

The AWG22 is upwards compatible with the AWG20 and also features differential outputs with a programmable common-mode voltage.

The module combines an excellent dynamic performance with a very high DC accuracy.

The module has 8 output ranges starting at 80mVpp up to 10.20Vpp, which covers a wide range of Unit Under Test input voltages.
A filter-bank with 4 Low Pass filters (1.2kHz, 12kHz, 40kHz, and 200kHz) provide excellent signal conditioning to obtain the best possible signal integrity. In addition there are 4 software selectable signal paths available for user defined filters.

The Module uses a combination of multiple DACs, sub-ranging and error correction to achieve a full 22 bit performance level. 

The result is an SNR and THD performance that surpasses 24-bit AWGs. The excellent linearity, step response, and DC accuracy makes it a very general purpose unit suitable for sine wave generation, ultra linear ramp generation and fast stepping signals. With 4M-word (12M-byte) of memory very complex signal shapes can be generated.

All these features ensure extremely accurate results when performing analog measurements. The unit is very suitable for testing ADCs on linearity and dynamic performance.
