Introducing the USB-1602HS-2AO
Overview: USB-1602HS-2AO features
The USB-1602HS-2AO is a multifunction high-speed measurement and control board supported under popular
Microsoft
®
Windows
®
operating systems. The device is compatible with both USB 1.1 and USB 2.0 ports,
(although the speed of the module maybe limited when using USB 1.1 ports).
The USB-1602HS-2AO provides the following features:
 Two single-ended 16-bit analog inputs, with one A/D converter per channel.
The maximum sampling rate is 2 MS/s per channel.
The input range is software programmable for ±10 V, ±2.5 V, or ±500 mV.
 Two synchronous 16-bit ±10 V analog outputs can generate waveforms at 1 MS/s per channel.
 16 synchronous digital inputs and 16 synchronous digital outputs
 Four 16-bit or 32-bit counters (can be configured to be gated)
 Two timer/pulse generators with pulse width (duty cycle) control
 Three 16-bit or 32-bit quadrature detectors to measure linear and rotary position
A 68-pin SCSI connector provides connections for all inputs and outputs except for the two analog inputs. Four
BNC connectors provide connections for the two analog inputs, and alternate connections for the external pacer
clock and external digital trigger input.
The USB-1602HS-2AO samples all analog inputs, digital inputs, and counter inputs simultaneously. You can
synchronize AI, AO, and DIO operations at rates of up to 1 MS/s (million samples per second), with aggregate
throughput up to 8 MS/s.
You can pace operations with an internal or external clock.
A 500 VDC isolation barrier between the field wiring and USB interface reduces signal noise and protects the
board and your computer from ground spikes. The USB 2.0 high-speed driver transfers data at rates up to
480 Mbps.
The device is powered by a 10 Watt regulated external power supply that is included with shipment. Factory
and self-calibration tables are stored onboard in EEPROM.
