MCC USB-1608FS-Plus Simultaneous USB DAQ Device

Digilent‘s MCC USB-1608FS-Plus USB-based DAQ device has eight simultaneous analog inputs (A/D per channel), 16-bit resolution, 100 kS/s/ch sample rate (400 kS/s aggregate), one 32-bit counter, and eight digital I/O. It offers software-selectable analog input ranges for ±10 V, ±5 V, ±2 V, and ±1 V. Each analog input channel has a dedicated 16-bit A/D converter for true simultaneous sampling of all eight inputs. This device is USB-powered and requires no external power.

With hardware paced mode, the maximum throughput rate is 100 kS/s for any one channel, up to about 400 kS/s aggregate for multiple channels. Use burst scan mode to run any number of channels at the maximum rate of 100 kS/s up to the full capacity of the 32K sample FIFO. The maximum sampling rate is 800 kS/s aggregate for all channels.

Each of the eight digital I/O channels is configurable for input or output. When configured for input, the digital I/O terminals can detect the state of any TTL-level input. The digital I/O channels are high-drive (24 mA) connections. A 32-bit event counter can accept a signal up to 1 MHz. The internal counter increments when the TTL levels transition from low to high.

The USB-1608FS-Plus has a bidirectional external clock terminal. When configured for input, A/D conversions can be paced by an external source. The USB-1608FS-Plus supports TTL-level input signals up to 100 kHz. When configured for output, this device can pace A/D conversions on a second device and acquire data from all input channels simultaneously. It provides an external digital trigger input and a trigger mode that is edge or level sensitive. Edge sensitive is software-selectable for rising or falling edge. Level sensitive is software-selectable for high or low level.

Software support includes DAQami, an optional out-of-the-box application for data logging, visualization, and signal generation. Data can be viewed in real-time or post-acquisition on user-configurable displays. Drivers are included for the most popular applications and programming languages, including Visual C++®, Visual C#®, Visual Basic®.NET, DASYLab®, LabVIEW™, MATLAB®, and Python™.
