If a portion of the waveform required for a measurement is not

measurement, the result will display "No Edges", "Clipped", "Low Signal",
"< value", or "> value", or a similar message to indicate that the
measurement may not be reliable.

Post Acquisition Processing
In addition to changing display parameters after the acquisition, you can perform all of the
measurements and math functions after the acquisition. Measurements and math
functions will be recalculated as you pan and zoom and turn channels on and off. As you
zoom in and out on a signal using the horizontal scale knob and vertical volts/division knob,
you affect the resolution of the display. Because measurements and math functions are
performed on displayed data, you affect the resolution of functions and measurements.
