Introduction

DAQ-2000 series are simultaneously sampling multi-function data acquisition cards with four-channel simultaneous analog inputs, two-channel analog outputs, digital I/O and timer/counter functions. The four high speed A/D converters provide simultaneous sampling to allow sample four channels at the same time. If more channels required, multiple cards can be synchronized by the system synchronization interface provided by DAQ-2000 series. The two analog output function can operate together with analog input function. This makes DAQ-2000 series the ideal devices for the stimulus/response test.
