DI-4108 USB DAQ Product Preview

USB-connected data acquisition system that provides up to 16-bit resolution for each of eight analog input channels. Each analog channel supports a programmable measurement range of ±200 mV to ±10 V

Continuing to fill our new product pipeline with state-of-the-art USB data acquisition products, DATAQ Instruments announces model DI-4108. The 4108 complements the previously announced model DI-4208. Both products are identical except for measurement range, and both support DATAQ Instruments’ new ChannelStretch™ technology to provide seamless channel expansion to a limit of 128 analog and 112 digital channels by simply connecting more devices to a single PC. More product features follow, but model DI-4108 is a USB-connected data acquisition system that provides up to 16-bit resolution for each of eight analog input channels. Each analog channel supports a programmable measurement range of ±200 mV to ±10 V. Like the DI-4208, sample rate throughput for DI-4108 analog channels is 160 kHz, and the instrument also supports up to seven discrete I/O ports, and a rate and counter input.

Model DI-4108 and ChannelStretch™ Support

ChannelStretch™ is the common thread that binds together not only the DI-4108, but also the DI-4208 and the DI-1120 starter kit. All three models in any mix support connection to a single PC and data acquired from the group synchronously and seamlessly flows into a single WinDaq application as though acquired from a single device. This approach makes channel expansion a snap for any current or future requirement. The ability to mix and match models also extends measurement range for any given application to an amazing ±200 mV to ±100 V per channel as a function of the specific models connected. Further, ChannelStretch™ is not limited to WinDaq software. The feature is fully implemented in the .Net class for Windows programmers and in the instruments’ protocol for other operating systems.
