Why Can't the Width level of the Window Trigger on the DL1500 Series be set to Below the Voltage Sensitivity?

The width level of the Window trigger cannot be set to a value less than the voltage corresponding to 1 division at the specified voltage sensitivity. For example, if the voltage sensitivity is set to 500 V/div, then the width level cannot be set below 500 V. This limitation is due to the fact that the trigger sensitivity of the DL1500 Series is 1 Divp-p.

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.
