Chapter 1

Introducing the USB-1608HS

This user's guide contains all of the information you need to connect the USB-1608HS to your computer and to the signals you want to measure.

The USB-1608HS is a USB 2.0 high-speed device supported under popular Microsoft® Windows® operating systems. The USB-1608HS is fully compatible with both USB 1.1 and USB 2.0 ports.

The USB-1608HS features the following:  With one A/D converter per channel, the USB-1608HS offers true simultaneous-sampling of up to eight

channels of 16-bit single-ended or differential analog input at 250 kHz per channel. Each channel can be independently-configured with software for either single-ended or differential input.

The input range of each channel can also be configured independently with software.

 Eight digital input lines and eight digital output lines

The digital output lines are driven low on power up and reset. Each digital line has an associated LED indicator that lights for the logic 1 (high) state. You can disable all input or output LEDs with a jumper–one jumper disables all input LEDs. A second jumper disables all output LEDs.

 A 32-bit counter capable of counting TTL pulses.  A 5 V, 2 A, AC adapter (MCC p/n PS-5V2AEPS) powers the USB-1608HS. This adapter ships with the

device.

 A synchronization input line (SYNC_IN) allows you to provide an external sampling clock for the analog

inputs. A synchronization output line (SYNC_OUT) lets you output the internal or external sampling clock of the USB-1608HS analog inputs.

 An analog trigger lets you start analog input conversions based on the value of a digital or analog signal. The USB-1608HS is shown in Figure 1. I/O connections are made to the screw terminals on the device.
