The PXIe-4309 samples up to 32 differential channels and multiplexes the analog input channels across eight simultaneously sampling ADCs. The module samples eight input channels up to 2 MS/s/ch (single channel per ADC), and 32 input channels up to 100 kS/s/ch (four channels per ADC). The module's flexible resolution ranges from 18 bits at 2 MS/s/ch to 28 bits at 2 S/s/ch. The module features on-board signal averaging and filtering, auto-zero measurement switching, and a chopping mode that uses a pair of channels to provide high levels of noise rejection and to enable accurate and repeatable nano-volt measurements.
