AUTOMATED WAVEFORM
MEASUREMENTS
Automated waveform measurements make it easier to obtain accurate
numerical readings.
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
maths operations.
 Advanced mathematics functions are found on some scopes, improving the ‘time to
answer’ even further. Some examples:
- FFT, Integrate, Differentiate, Logarithm, Exponent, Square root, Absolute
- Sine, Cosine, Tangent, Radians, Degrees
- Scalars, with user-adjustable variables and results of parametric measurements.
Automated measurements appear as on-screen
alphanumeric readouts, and are more accurate than direct
graticule interpretation.
Examples of fully automated waveform measurements:
 Period  Duty Cycle +  High
 Frequency  Duty Cycle -  Low
 Width +  Delay  Minimum
 Width -  Phase  Maximum
 Rise time  Burst width  Overshoot +
 Fall time  Peak-to-peak  Overshoot -
 Amplitude  Mean  RMS
 Extinction ratio  Cycle mean  Cycle RMS
 Mean optical power  Cycle area  Jitter
