The DI-158 Series of Starter Kits break new ground in price and performance, offering advanced features and options usually reserved for more expensive instruments. A channel scan list, high sample throughput rates, and an advanced computer interface are just some of the features that combine to produce a robust instrument that can be applied to nearly any data acquisition situation where low and high level signals need to be acquired to a PC.

The DI-158 offers an option of two programmable gain and full scale ranges. These USB devices are powered through the interface - no external power is required. Gain configurations are 1, 2, 4, and 8 with a full scale range of ±10 Volts. Also available is a version supporting gain factors of 1, 2, 4, 8, 16, 32, 64, 128, 256, and 512 with a full scale range of ±64 Volts.

Voted Best Data Acquisition Product

Evaluation Engineering Magazine named the DI-158 Best New Data Acquisition Product of 2004 as voted on by their readers. Read the full article here.

High Sample Throughput

Sample throughput rates up to 14,400 samples per second are supported. The High Speed version of WinDaq/Lite Recording software is required to reach these high sample rates. WinDaq/Lite is limited to recording rates of 240 Hz throughput.

Easy to Connect and Use

Two built-in, 8-position screw terminal connectors allow easy and secure access to all DI-158 signal I/O connections without the need for extra options.

Small Package

The DI-158 is housed in a small plastic enclosure measuring 66D × 66W × 28H mm (2.6D × 2.6W × 1.1H inches).

WinDaq Software Included

The DI-158 data acquisition starter kit includes WinDaq/Lite recording software and WinDaq Waveform Browser playback and analysis software. An extra cost high speed acquisition version of WinDaq is available for these products that allows you to record at the speed of the instrument. WinDaq/Lite is limited to recording rates of 240 Hz throughput. Please Note: WinDaq Acquisition Triggered Mode is not available with the DI-158 Series.
