USB-3100 Series USB Voltage and Current Output Features • 4, 8, or 16 analog outputs • 16-bit resolution • Update rates from 100 S/s to 100 kS/s • 4, 8, or 16 analog current outputs available • High-drive output available The USB-3100 Series provides up to 16 voltage/current output channels, with some devices offering high-drive analog outputs. The USB-3101FS includes 4 simultaneous output channels with 250 Vrms channel-to-ground isolation. Overview The USB-3100 Series are voltage and current output USB 2.0 full-speed devices. Each device provides four, eight, or 16 voltage outputs. The USB-3102/3104/3106 also provide four, eight, or 16 current outputs. All devices provide synchronous and concurrent voltage updates. All USB-3100 Series devices except the USB‑3101FS provide eight digital I/O lines and one 32-bit event counter. Analog Output All USB-3100 Series devices provide either four, eight, or 16 channels of 16-bit analog output. All USB-3100 Series devices except the USB-3101FS have a synchronous DAC load connection pin that simultaneously updates DAC outputs on multiple devices. You can configure this with software as an input (slave mode) or as an output (master mode). USB-3101FS: Each channel has a fixed ±10 V voltage output range. Outputs can be updated individually or simultaneously. Each channel has a D/A converter (DAC) that produces a voltage signal. Each channel also has ±30 V overvoltage and indefinite short-circuit protection. The USB-3101FS has 250 Vrms channel-toground isolation that protects the device and computer from ground spikes and ensures a reliable data stream, making it suitable for high-voltage applications. All Other USB-3100 Series Devices: 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. • Digital I/O, counter/timer available • Synchronous update available Supported Operating Systems ‑ • Windows® 11/10/8/7/Vista®XP 32/64-bit Digital I/O All USB-3100 Series devices except the USB-3101FS have eight bidirectional DIO lines. All digital pins are floating by default. A screw terminal connection is provided to configure for pull-up (+5 V) or pull-down (0 V). Counter Input Each USB-3100 Series device except for the USB-3101FS has a 32-bit event counter for counting TTL pulses. The counter increments when the TTL levels transition from low to high. The counter accepts frequency inputs of up to 1 MHz. USB-3100 Series Selection Chart Model Voltage Output Update Rate Current Output Counter/ Timer Current Output (USB-3102/3104/3106 Only) These devices provide 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. Measurement Computing
