Threshold
Threshold Settings
The threshold is defined as follows: When the level of the captured signal is higher than
the threshold, it is Logic High, while lower than the threshold is called Logic Low. From
the quick setting, you can select to set the commonly used voltage level, and then adjust
the voltage. It is proposed that the threshold of a signal voltage to be measured is set at the
half of the signal voltage.
Schmitt Circuit Threshold Mode
When the threshold is only one set of voltage and when the voltage is close to the threshold
during the signal transition, the signal may be slowed down to allow the device to capture a
signal that may be 0 or 1 at this critical point. This will cause trouble for viewing the
waveform, as shown in Figure CH-01 below.
