Why Can't I use the Measurement Function on Data Loaded From Previous DL1540 Acquisitions?

The measurement function can be used only when data are saved in the ACQ (BIN) format. In addition, when data are saved in this format, all functions including waveform zoom can be used in the same fashion as with the captured data. When P-P data are saved, the waveform can only be displayed; measurement functions and other functions cannot be used.

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.


Oscilloscopes are a common type of test instrument used to 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.
