DL950 Acquisition Application Programming Interface

This high-speed data acquisition system includes software (DL950ACQAPI.dll) that provides an application programming interface (API) for obtaining waveform data being acquired by the DL950 series. 

API Overview

The API is provided as a dynamic link library (DLL). The API can be used by linking user applications with this DLL.
The API only supports data acquisition in free run mode.

Free run mode
Free run mode is used to acquire data from the start to the end of waveform acquisition.
* Zoom waveform display is not possible on the DL950 while waveform acquisition in free run mode is in progress.
