• Press Offset, then rotate the multifunction knob to set the vertical offset of
the operation results. You can also directly rotate Wave Vertical POSITION or
enable the touch screen to adjust the vertical offset.
• Press Size, then rotate the multifunction knob to select the waveform size.
Press down the knob to select it. You can also press Size continuously or enable
the touch screen to select the channel. The available sizes include "Small",
"Medium", and "Large". In addition, you can also rotate Wave Vertical SCALE
to adjust the waveform size.
• Press More > AutoSetting to adjust the vertical scale and offset of the
operation results to the optimal value according to the current configuration for
better observation.
• Press More > Sensitivity to set the sensitivity of the digital signal converted
from the analog signal on the source. For setting methods, refer to descriptions
in "
Parameter Setting Method
".
• Press More > Label to set the label for math operation results. For details, refer
to the descriptions in "
Math Operation Label
".
9.1.9 "NOT" Operation
Performs logic "NOT" operation on the waveform voltage values of the specified
sources point by point and displays the results. In operation, when the voltage value
of the source channel is greater than the threshold of the corresponding channel, it is
regarded as logic "1"; otherwise it is logic "0". The results of logic "NOT" operation of
two binary bits are as shown in
Table 9.5 Logic "NOT" Operation
.
