Data Acquisition Instrument

The DI-145 USB data acquisition instrument features four ±100-V analog channels and two dedicated digital inputs. The included DATAQ WinDaq data acquisition software (DAS) enables you to display and record data to a PC hard drive in real time. Once recorded, data can be played back, analyzed, or exported to an array of data acquisition and spreadsheet formats.

DATAQ also provides access to the DI-145 data protocol, which enables access to the DI-145 on any Windows, Linux, or MAC OS. In addition, .NET control is available to Windows users who wish to use a third-party programming language (e.g., Microsoft’s Visual Basic or National Instruments’s LabVIEW) to interface with the DI-145.

The four ±10-V fixed differential channels are protected from transient spikes up to ±150 V peak (±75 V, continuous). A 10-bit ADC provides 19.5-mV resolution across the full-scale measurement range. Digital inputs are protected up to ±30 VDC/peak AC. The digital inputs enable you to use a switch closure or TTL signal to remotely insert event marks or record data to disk.

The DI-145 measures 1.53” × 2.625” × 5.5” (3.89 cm × 6.67 cm × 13.97 cm) and weighs 3.6 oz. The data acquisition instrument costs $29 and includes a mini screwdriver, a USB cable, WinDaq/Lite DAS, access to the data protocol, and .NET control.
