In General

WinDaq Acquisition is a Windows™-based data acquisition software package that gives any of our hardware products simultaneous real time display and data storage to disk capability. There are three basic software packages: WinDaq/Lite, which allows you to acquire, display, and record data at a total throughput rate of 240Hz; WinDaq/Pro, which gives you equal throughput rate for each channel and is only restricted by your hardware (PC and data acquisition device); and WinDaq/Pro+, which allows you to sample channels at variable rates (see Sampling Different Channels at Different Rates). There are two basic software packages available for your DI-149: WinDaq/Lite (free), which allows you to record data at a maximum throughput of 240 Hz; and WinDaq/HS, which allows you to record at the highest speed of the device (10 kHz throughput or 11 kHz throughput for 11 enabled channels (8 analog and 3 digital)). There are two basic software packages available for your DI-155: WinDaq/Lite (free), which allows you to record data at a maximum throughput of 240 Hz; and WinDaq/HS, which allows you to record at the highest speed of the device (10 kHz throughput).

Using WinDaq Acquisition, you will be able to perform the following functions:

Record waveform data to disk in the background while running any combination of programs in the foreground.
Annotate your data with descriptive event marker comments, even while recording to disk.
Monitor the real time display in a smooth scroll or triggered sweep mode of operation, scaled to any unit of measure.
And much, much more.
