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.
Functions
This software can be used to perform the following functions. For details, see User’s Manual.
- Initializing the API
- Connecting and disconnecting from measuring instruments
- Setting parameters
- Getting waveform data

Product Overviews
Test and measurement engineering work groups can have differing priorities and requirements, which often results in multiple instrumentation systems and data file formats, as well as incompatible reporting. This lack of effective communication between groups and instruments causes decreased efficiency and quality and increased spending and time to market. Unify test and measurement instrumentation, software, and data across engineering teams with a suite of solutions that caters to the different needs of engineering work groups, including accurate power data, fast sampling rates, long recordings of multiple different input types, and insights into waveform data.
