Why Does the DLM2000 Save Only One Acquisition Waveform Even Though History Mode is set to ALL?

The DLM2000 can save all history acquisition waveforms into one file, if the data type is set to Binary (file extension *.WDF) and History Mode is set to All. If the data type is set to ASCII, only the latest acquisition waveform will be saved, regardless if History Mode is set to All or One. When saving Binary history files, please make sure that the Sampling Mode, in the ACQUIRE menu, is set to RealTime.

Mixed Signal Oscilloscopes

A mixed signal oscilloscope is an instrument enabling the simultaneous, time correlated observations and analysis of analog with digital (logic) signals, to establish causal relationships between the various areas of a device's electronics. They are purpose-built tools for troubleshooting electrical anomalies, measuring parametric values, and monitoring cause and effect relationships between signals.


Capture, analyze, and troubleshoot electrical or real-world physical signals. Oscilloscopes observe the change of electrical signals over time, continuously graphed on a display as voltage or amplitude vs. time.
