MEASUREMENT COMPUTING. 16-Bit High-Speed Multifunction DAQ Devices Features • 16-bit high-speed USB devices • Acquisition rates up to 500 kS/s • 8 differential (DIFF) or 16 single-ended (SE) analog inputs • Up to 2 analog outputs • 8 digital I/O • Two 32-bit counter inputs • One timer output • OEM version available Supported Operating Systems • Windows® 10/8/7/Vista®XP 32/64-bit • Android™ Overview USB-1608G Series devices are low-cost, high-speed, analog and digital I/O USB devices. All of these devices offer up to eight DIFF or 16 SE analog inputs, eight digital I/O channels, two counter inputs, and one timer output. The USB-1608GX-2AO standard and OEM version offers two, 16-bit analog output channels with DAC rates up to 500 kS/s. Analog Input USB-1608G Series devices provide 16-bit analog inputs that are software-selectable as eight DIFF or 16 SE inputs. These devices also support input ranges of ±10 V, ±5 V, ±2 V, and ±1 V that are software-selectable per channel. Analog Output (USB-1608GX-2AO only) The USB-1608GX-2AO standard/OEM board has two 16-bit analog outputs that can be updated at a rate of 250 kS/s per channel; one output can be updated at a rate of 500 kS/s. The output range is fixed at ±10 V. Trigger Input USB-1608G Series devices have an external digital trigger input. The trigger mode is software-selectable for edge- or level-sensitive mode. You can configure edge-sensitive mode for either rising or falling edge. In level-sensitive mode, you can configure for either high or low level. The default setting at power up is edge-sensitive, rising edge. Retrigger Mode Users can set up repetitive analog input trigger events. The trigger is automatically re-armed after it is activated. The A/D trigger count (the number of samples you want per trigger) is configurable with software. Digital I/O Eight bidirectional digital I/O lines are individually configurable for input or output. The DIO terminals can detect the state of any TTL-level input. Users can configure for pull-up (+5 V) or pull-down (0 V) with an onboard jumper. Counter Input Two 32-bit event counters are provided to count TTL pulses. The counters accept inputs of up to 20 MHz. Timer Output The PWM timer output generates a pulse output with a programmable frequency in the range of 0.0149 Hz to 32 mHz. The timer output parameters are software-selectable.
