threshold of Source A (or Source B) in logic operation. For setting methods,
refer to descriptions in "Parameter Setting Method".
Press Offset, and then rotate the multifunction knob to adjust the vertical
offset of the operation results. You can also directly rotate Wave Vertical
POSI TI ON or enable the touch screen to adjust the vertical offset.
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 AutoSetting 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".
"OR" Operation
Performs logic "OR" operation on the waveform voltage values of the specified
sources point by point and displays the results. I n 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 OR operation of
two binary bits are as shown in Ta b l e 6-3.

Press Operation continuously to enable or disable the "OR" operation function.
Tip
The thresholds of the digital channels (D0-D15) are respectively set in the LA
module.
