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.

DC to 48kHz spectrum, 1kHz carrier, 96ksps.

The two channels are ideal for stereo and phase shift measurements. The selectable 22kHz or 100kHz low pass filters reduce the out of band noise.

The internal clock sources can generate all standard audio sample rates and more. The External clock and trigger capability give the user full control of the measurement timing. If the PG24192 is used as generator, the clocks of the two units can be synchronized via the local bus capability of the PXI backplane. This allows coherent clocking for best measurement results.
