HTPXI4484:PXI Simultaneous DAQ

The HTPXI4484 is a 16-bit A/D high-precision simultaneous DAQ device with the highest sampling rate of 2MSa/s per channel. There are 8 independent single-ended or 4 independent differential inputs, and each channel features an independent 16-bit ADC architecture and a signal conditioning circuit to achieve the highest performance of Hitech multifunction data acquisition hardware, which is ideal for such applications as sound and vibration etc. With the HTPXI4484, you can set up multichannel simultaneous DAQ systems within any PXI chassis.
