USB 8-channel, 16-bit, 250kHz, 2AO simultaneous sampling analog I/O module.

Overview
With one A/D converter per channel, the USB-1608HS Series offers true simultaneous sampling of up to eight 16-bit analog inputs at 250 kHz per channel. The USB-1608HS Series is housed in a heavy-duty chassis with integrated mounting slots, ensuring that the hardware is rugged enough for any DAQ application. A required external power supply is included.

Analog Input
The USB-1608HS Series provides eight single-ended or eight differential analog inputs. Users can mix SE and DIFF channels. Each input has a dedicated 16-bit A/D converter for true simultaneous sampling per channel. The input range is softwareselectable, and the sample rate is 250 kS/s per channel. Users can pace operations with an internal or external clock.

Analog Output
The USB-1608HS-2AO provides two independent, 16-bit analog voltage outputs. The throughput rate is 70 kS/s for one channel, and 35 kS/s for two channels. Users can clock output operations with the onboard scan clock. Users can enable remote sensing for each output to compensate for any voltage drop error that may occur.

Digital I/O
The 16 digital I/O lines are configured as 8 inputs and 8 outputs. The digital I/O transfer rate is up to 8000 port or single bit reads/writes per second, systemdependent. Users can configure the pull-up/down configuration with onboard jumpers. Each DIO pin has an associated LED to indicate the digital input/output state.

Trigger Input
An analog trigger input can be used to start an acquisition. The trigger threshold range is ±10 V. The threshold resolution 12 bits. Users can set the following trigger options:

• Positive or negative slope
• Edge or level sensitive
• Retrigger on or off

The trigger is automatically rearmed after acquiring a specified number of samples.

Counter Input
The counter channel is a TTL-level input to a 32-bit event counter. The counter increments when the TTL level transitions from low to high. The counter can count frequencies of up to 1 MHz.

Clock I/O
Users can pace operations with the internal clock or with an external source. Two terminals are provided for external clocking and multi-unit synchronization:

• SYNC_IN externally paces A/D conversions. TTL-level input signals of up to 250 kHz are supported.
• SYNC_OUT outputs the clock for

A/D conversions.
Users can connect the SYNC_OUT pin on one device to the SYNC_IN pin of a second device and acquire data synchronously from 16 analog input channels.
