Features
WPI-118 is a fast, high-resolution data acquisition system suitable for most data recording studies in the research laboratory. It offers eight analog input channels, eight digital outputs, four digital inputs and two DACs. The hardware connects to PC-compatible computers via the popular USB interface, so setup is plug-and-play easy. The small physical size of the WPI-118 requires very little bench space.
Analog Outputs
WPI-118 offers two +/- 10V Analog Outputs (DACs). Each is independently programmable and can be synchronized to work together. Basic stimulus parameters for each DAC, such as pulse width, frequency and amplitude, can be changed on-the-fly using handy controls located in the Data-Trax software toolbar. Standard protocols include pulse, train, and step waveforms. Each standard protocol allows the quiescent state to be a holding voltage, thereby making it ideal for voltage clamping applications.
Resolution and Noise
WPI-118 employs a 16-bit A/D converter to sample data over its 10-Volt input range. Typical noise on any input is less than 1 millivolt. This allows the recording of signals from 10 mV to 10 V without the need for additional external gain.
Digital Input/Output
Eight digital output lines are available. The digital output connectors are industry standard BNC, eliminating the need for custom cables. Programming the output lines is point-and-click easy as well, no complicated scripting language is required. Four digital input lines are also provided, with one configured as an external trigger.
Speed
The WPI-118 is a fast recorder. At top speed it can collect 100,000, 16-bit samples per second on a single channel. With eight channels enabled, it can collect data at 10,000 samples per second on each of the open channels.
USB Connection
Connection to the computer is accomplished over the popular USB port. This eliminates the need to install special interface cards and even makes the WPI-118 compatible with notebook computers. The WPI-118 has a small footprint, so it fits in even the tightest rack spaces.
System Requirements
WPI-118 requires a minimum Pentium II-level computer running Windows 98, ME, 2000 or XP with at least 64 megabytes of RAM, and at least 10 megabytes of free space on the hard drive. Internet connection is required for free automatic upgrades.
