Automatic measure ments tip

A symbol appears next to a measurement if a vertical signal clipping condition exists. Part of the waveform is above

or below the upper or lower edge of the screen. Signal clipping causes inaccurate measurements. To obtain an accurate

measurement, turn the Vertical Scale and Position knobs so that all of the waveform is on the screen.

Taking a measurements snapshot

The Snapshot measurement (in the Measurement menu) displays all single-channel measurements on one screen
