Press Size, and 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 it. The available sizes include "Small",
"Medium", and "Large". Also, you can rotate Wave Vertical
SCALE to
adjust the waveform size.
Press More AutoScale to adjust the vertical scale and offset of the operation
results to the optimal value according to the current configuration, so as to
better observe.
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 descriptions in "Math Operation Label".
"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 6-5.

Press Math Math1 Operator to select "!A":
Press Operation continuously to enable or disable the "NOT" operation
function.
Press SourceA, and rotate the multifunction knob to select the channel for
SourceA. Then press down the knob to select the channel. You can also press
SourceA continuously or enable the touch screen to select the channel. The
available channels for SourceA are CH1-CH4 and D0-D15.
Note: Only the channels that have been enabled currently can be selected.
If Source A (or Source B) selects CH1, press More Thre.CH1 to set the
threshold of Source A (or Source B) in logic operation. For setting methods,
refer to descriptions in "Parameter Setting Method".
If Source A (or Source B) selects CH2, press More Thre.CH2 to set the
threshold of Source A (or Source B) in logic operation. For setting methods,
refer to descriptions in "Parameter Setting Method".
