Digilent USB-3102 Voltage and Current Output USB Device

Features and Specifications

• 4 voltage/current output channels
• 16-bit resolution
• Voltage output +/-10 V, 0 V to 10 V
• Current output 0 mA to 20 mA typ
• 100 S/s update rate
• Eight digital I/O
• One counter input
• USB-bus powered (No external power is required)

The USB-3102 provides four channels of analog voltage output, four channels of analog current output, eight digital I/O connections, and one 32-bit event counter (counts TTL pulses). It has a quad (4-channel) 16-bit digital-to-analog converter (DAC). Each D/A converter output controls a voltage and current channel pair simultaneously.

The voltage output range of each DAC channel is set independently with software for either bipolar, unipolar or current. The bipolar range is +/-10 V, the unipolar range is 0 to 10 V, and the analog current range is 0 to 20 mA. Each voltage/current channel pair can be updated individually or simultaneously. A bidirectional synchronization connection allows a simultaneous update for the DAC outputs on multiple devices.

The USB-3102 features eight bidirectional digital I/O connections. You can configure the DIO lines as input or output in one 8-bit port. All digital pins are floating by default. A screw terminal connection is provided for pull-up (+5 V) or pull-down (0 volts) configuration.

The USB-3102 is a USB 2.0 full-speed device that is supported under popular Microsoft Windows operating systems. It is fully compatible with both USB 1.1 and USB 2.0 ports.

USB-3100 Series Overview

The USB-3100 Series features up to 16 analog outputs, 8 digital I/O, and one 32-bit counter input. Each channel is software-selectable for either a bipolar voltage output range of +/-10 V or a unipolar range of 0 V to 10 V. Channel outputs can be updated individually or simultaneously. USB-3102 also features 0 mA to 20 mA of current output. Each DAC controls a voltage/current channel pair simultaneously. Each channel pair can be updated individually or simultaneously.

• USB-3102 - 4 Channels
• USB-3104 - 8 Channels
• USB-3114 - 16 Channels

Software support includes DAQami, an out-of-the-box application for data logging, visualization, and signal generation. Data can be viewed in real-time or post-acquisition on user-configurable displays. Drivers are included for the most popular applications and programming languages including Visual C++, Visual C#, Visual Basic.NET, DASYLab, LabVIEW, MATLAB, Linux, and Python.
