NI’s PXI express module


National Instruments has announced the NI PXIe-449x devices, the most flexible high channel count dynamic signal acquisition (DSA) modules to provide AC/DC coupling both for sensor measurements with a microphone or accelerometer and voltage measurements from a tachometer or device under test.

Features and USP: The NI PXIe-449x modules feature a choice of 8 or 16 channels with 24-bit analog-to-digital converters (ADCs) per channel and 113 dB dynamic range. The large dynamic range minimises the noise floor, making it easy to detect even the smallest vibration and acoustic signals. It also provides software selectable gains that help engineers configure gain on each channel for the best signal-to-noise ratio possible. With this module, engineers can easily synchronise physical measurements of any type and correlate real time events. The modules sync effortlessly with the NI SC Express family of data acquisition modules, which provide signal conditioning and connectivity ideal for temperature, strain and high-voltage acquisition.
