The API is provided as a dynamic link library (DLL). The API can be used by linking user applications with this DLL.
The API supports two acquisition modes: free run and trigger. The API supports connections to multiple DL950s but does not support multi-unit synchronization (/C50 option).
(1) 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 during waveform acquisition in free run mode.
Waveform acquisition specifications in free run mode
Maximum data rate: 320 MB/s (10 MS/s×16ch) for 10Gbit Ethernet connection
Maximum data rate: 6.4 MB/s (200 kS/s×16ch) for 1Gbit Ethernet/USB connection
Maximum waveform acquisition time: 10 days (maximum operation time guaranteed for this API)
(2) Trigger mode
Trigger mode is used to acquire waveform using triggers. There are two trigger modes available with the API:
(i) Synchronous mode in which the DL950 acquires waveforms synchronously with the PC.
(ii) Asynchronous mode in which the DL950 acquires waveforms asynchronously with the PC.
Note that the API does not support the following features.
This software can be used to perform the following functions. For details, see User’s Manual.

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.
Having multiple memory options allows engineering groups to optimize how data is stored, no matter if you need to record for a long time at slower sampling rates, do a fast capture at high sampling rates, or anything in between.
The Yokogawa Test&Measurement DL950 ScopeCorder operates as an oscilloscope and incorporates the ability to record data for long periods of time like a data acquisition recorder. There are four memory types on the DL950 ScopeCorder: internal memory, solid state drive, flash memory, and PC storage through the IS8000 Integrated Test and Measurement Software Platform. This videos talks about the advantages of each of these and how to pick the best data recording method for you.
