C. Set the base value calculation strategy. When set to Histogram, the value at the lower half
of the waveform will be counted, and the value with the maximum probability will be
identified as the base value; when set to min, the minimum value of the waveform will be
identified as the base value

Threshold
Measurement thresholds can be defined by the user. This is more flexible than fixed thresholds. For
example, for pulse-width measurement, the threshold can be specified rather than fixed at 50%. For
rise time, the lower / upper thresholds can be specified rather than fixed at 10% / 90%.
Changing the default threshold may change the measurement results of relevant measurement items,
such as Period, frequency, +width, -width, +duty, -duty, +BWidth, -BWidth, delay, T@M, rise time, fall
time, CCJ, cycles, rising edges, falling edges, edges, Ppulses, Npulses, and delay measurement.
Touch Config ＞ Threshold in the measure dialog box to recall the threshold dialog box:
A. Set measurement threshold source
B. Set the type of threshold
C. Set the upper value
D. Set the middle value
E. Set the lower value
F. Return to the previous menu
