MPS-HD2416 16 channel 24 bit high dynamic range acquisition card

1HD2416 Data CollectorIntroduction

MPS-HD2416 is a 16 channel 24 bit high dynamic range signal acquisition card with USB bus, which can be used in high-precision signal measurement, portable data acquisition, vibration and audio signal analysis and other fields.

The MPS-HD2416 acquisition card has sixteen synchronous voltage acquisition channels with a range of ± 5V, and the sampling rate can be adjusted from 1K to 64K in seven levels. It can achieve uninterrupted continuous real-time acquisition and data transmission under high-speed sampling. The MPS-HD2416 acquisition card has the advantage of low sampling noise, with a bottom noise of only 66uVrms (± 5V full-scale) at a sampling rate of 64KAt a sampling rate of 1K, it can be as low as10uVrms， Effective resolution up to 20.1 bitsAt the same time, MPS-HD2416 has six optional channel input modes, supporting the combination of various characteristics including differential and single ended, high input impedance and low input impedance, DC coupling and AC coupling, whether to support IEPE (ICP) constant current power supply, etc. Different input modes can be adapted to different application scenarios, and each channel can be independently configured, making mixed measurement of multiple signals more friendly.

The MPS-HD2416 acquisition card adopts USB 2.0 (High Speed) bus protocol to connect with the computer, supports all Windows operating systems, and supports plug and play and hot plugging. MPS-HD2416 provides a universal DLL driver that supports direct calling in most programming languages, and provides examples in languages such as LabVIEW as programming references. In addition, the MPS-HD2416 acquisition card also comes with a free set of multifunctional testing software. The testing software can achieve real-time signal acquisition and display, data recording and playback, spectrogram and other commonly used basic functions, as well as software filtering, edge triggering, variable sampling rate, calculation of amplitude frequency and mean extreme value, automatic timing acquisition, signal to audio playback and many other advanced functions. Users who cannot program independently can also use this software to complete applications, greatly reducing the threshold for device use.
