The 8402 is a flexible general purpose acquisition card, with built-in signal conditioning for almost any type of transducer. It has the capability of high sample rates and synchronous parallel sampling with an additional tachometer input. It also offers a choice of AC or DC coupling to direct voltage inputs and support for IEPE† transducers, including those with TEDS. Importantly has a large number of analogue amplifier steps to maximize resolution. Additionally, the 8402 card has a dedicated tachometer channel. This card offers the flexibility of capturing data in 24-bit resolution or in 16-bit resolution. When working in the frequency domain or the order domain this card is the natural choice.
