USB-3100 Series

Analog Output

All USB-3100 Series devices provide either

four, eight, or 16 channels of 16-bit ana-

log output.

USB-3101FS: Each channel has a fixed

±10 V voltage output range. Outputs can

be updated individually or simultane-

ously. 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-to-

ground 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.

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 simultane-

ously. Each channel pair can be updated

individually or simultaneously.

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 coun-

ter 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.

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.

Synchronous DAC Updates

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).
