AUTOMATED MEASUREMENTS
AND ANALYSIS
Automated waveform measurements make it easier to obtain accurate
numerical readings.
Determine what you need
 Most scopes offer front-panel buttons and/or screen-based menus to take
accurate automated measurements.
 Basic choices on most scopes include amplitude, period and rise/fall time.
Many digital scopes also provide mean and RMS calculations, duty cycle, and
other math operations.
 Measurement “gating” allows you to determine the section of the waveform
used to calculate measurements.
 Channel math functions let you add, subtract and multiply waveforms. Use
waveform multiplication to multiply voltage and current to get power. Use
subtraction to approximate a differential measurement.
 A Fast Fourier Transform (FFT) feature will let you see the frequency spectrum
of an acquired waveform.
Examples of fully automated waveform measurements:
Time Frequency Period Rise Time Fall Time
Delay Phase Positive Pulse Width Negative Pulse Width
Positive Duty Cycle Negative Duty Cycle Burst Width
Amplitude Peak-to-peak Amplitude Max Min
High Low Positive Overshoot Negative Overshoot
Mean Cycle Mean RMS Cycle RMS
Others Positive Pulse Count Negative Pulse Count Rising Edge Count Falling Edge Count
Area Cycle Area Phase Delay FR
Delay FF Delay RR
Automated measurements appear as on-screen alphanumeric readouts, and are more
accurate than direct graticule interpretation
