High-Low Setup. The TekScope instrument determines the 10%, 50%,
or 90% levels of the selected waveform and then uses them to
calculate the measurements. You can choose the method used to
determine these levels:
H Histogram sets the values statistically; it finds the most common
value either above or below the midpoint (depending on whether
it is defining the high or low reference level). Since this
statistical approach ignores short-term aberrations (overshoot,
ringing, noise), histogram is the best method for measuring
digital waveforms and pulses.
H Min-max uses the highest and lowest values of the waveform
record. This method is best for measuring waveforms that have
no large, flat portions at a common value, such as sine waves and
triangle waves.
