The WFD16 is a 16 bit Waveform Digitizer for high-speed / high resolution waveform capturing and analyzing. The fully differential signal path ensures an exceptional high signal quality. Despite this emphasis on signal quality the WFD16 also has a good DC accuracy.

The module features differential inputs with a 50O or 10kO termination and a with a programmable common-mode voltage. For single ended applications the negative input can be connected to the internal DC-offset voltage source to cancel out a DC component of the input signal. The clock can come from the backplane or from the front panel.

The module has 16 input ranges starting at 0.512Vpp up to 7.68Vpp, which covers a wide range of Unit Under Test output voltages.

A filter-bank with 3 Low Pass filters (15MHz, 30MHz, and 60MHz) removes out-of-band noise and provides anti-aliasing.

The Module uses a state of the art ADC which provides an excellent SNR, THD and linearity. The unit is an excellent choice for dynamic signal capturing and analysis as well as time domain analysis. With 8M-word (16M-byte) of memory long signal streams can be captured.

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