The AWG16 is a 16 bit Arbitrary Waveform Generator for high-speed / high resolution waveform generation. The fully differential signal path from the DAC all the way to the outputs ensures an exceptional high signal quality. Despite the emphasis on signal quality the AWG16 also has a very good DC accuracy.

The module features differential outputs with a programmable common-mode voltage. For single ended applications the positive output as well as the negative output can be used. The clock can come from the backplane or from the front panel.

The module has 8 output ranges starting at 0.48Vpp up to 5.12Vpp, which covers a wide range of Unit Under Test input voltages.

A filter-bank with 3 Low Pass filters (15MHz, 30MHz, and 60MHz) provide excellent signal conditioning to obtain the best possible signal integrity.

The Module uses a self calibrating DAC which results is an excellent SNR, THD and linearity. For DC levels there are various calibration DACs that allows an unsurpassed DC accuracy for a high speed module. The unit is an excellent choice for sine wave generation as well as high speed linear ramp generation. With 8M-word (16M-byte) of memory very complex signal shapes can be generated.

All these features ensure a very accurate result when performing analog measurements. The unit is very suitable for testing ADC linearity and dynamic performance.
