Time-Domain Measurements

Using the time scope, you can make a number of time-domain signal measurements.

The following measurements are available:

Data Cursors - Puts screen cursors and waveform cursors.
Signal Statistics - Displays maximum, minimum, peak-to-peak difference, mean, median, RMS values of a selected signal, and the times at which the maximum and minimum occur.
Bilevel Settings - Displays information about a selected signal's transitions, aberrations, and cycles.
Peak Finder - Displays maxima and the times at which they occur.

Peak Measurements

Enable Peak measurements from the Measurements tab by clicking the Peak Finder button. The Peaks pane appears at the bottom of the time scope window. For the Num Peaks property, enter 8 and press Enter. In the Peaks pane, the time scope displays a list of 8 peak amplitude values and the times at which they occur.
