The DI-148U is a PC-based instruments that offers high data acquisition performance for an extremely low price. Each DI-148 has eight single-ended analog input channels with a fixed ±10 Volt full scale range. Analog to Digital conversion resolution is 10 bits, allowing a minimum voltage sensitivity of ±19.5mV. Six bi-directional TTL ports may be used for general-purpose control.

High Sample Throughput

Supports sample throughput rates up to 14,400 samples per second. 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-148 signal I/O connections without the need for extra options.

Small Package

The DI-148 is housed in a small plastic enclosure measuring 66D × 66W × 28H mm (2.6D × 2.6W × 1.1H inches).

WinDaq Software Included

The DI-148 data recorder 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. WinDaq/Lite is limited to recording rates of 240 Hz throughput. Please Note: WinDaq Acquisition Triggered Mode is not available with the DI-148.
