Key product information and technical features.
Within NI's S Series, the PXI-6122 uses a dedicated 16-bit ADC for each analog input channel. Its architecture samples all four channels simultaneously rather than sharing one converter between channels.
The module combines analog acquisition, digital I/O, counter/timer functions, and digital triggering. It has no analog output channels.
