DL950 Flash Acquisition Data Access Library

This software (DL950FACQAPI.dll) provides an application programming interface (API) for transmitting waveform data stored in the flash acquisition area of a DL950 to a PC.

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 Flash Acquisition Data Access API provides applications with a function for extracting flash acquisition waveform data stored in a DL950 directly to a PC without loading the data into the instrument.
Note that the acquisition memory is used as a temporary buffer when flash acquisition waveform data is extracted through the use of this API.
Thus, data and history information in the acquisition memory that have not been saved to a storage device will be cleared. Waveform data stored in the flash acquisition area is not affected.

 

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
  • Getting the measurement conditions of waveform data stored in the flash acquisition area
  • Getting the waveform data stored in the flash acquisition area

How-tos

    Overview:

    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.
