The PD24222 is a PXI, Dual Channel Digitizer. It features fully differential inputs and a very low distortion. For differential measurements the input signals may have any common mode level as long as the common mode level plus signal stay within the -10V to +10V range. Alternatively AC coupling can be used. For single ended applications the PD24222 has a programmable DC offset source that can be connected to the negative input. This ensures the full resolution of the converter can be maintained when capturing signals with a DC offset.
The unit is very suitable for audio type of measurements. The flexible input ranging and coupling allow easy adaptation to a wide range of Unit Under Test output voltages.
