• For FFT math operation setting label, refer to descriptions in "
Math Operation
Label
".
• Press More > More > Color Grade to enable or disable the color grade display
of the FFT operation results. When enabled, different colors are displayed on the
screen to indicate the times of data acquisition or acquisition probability.
• Press More > More > Reset ColorGrade to clear the color grade display and
then display the color grade again.
TIP
FFT shortcut operation: Enable the touch screen, and then tap the function navigation icon
at the lower-left corner of the screen to open the function navigation. Then, tap the "FFT" icon
to open the FFT menu. This oscilloscope supports 4 FFTs: FFT1, FFT2, FFT3, and FFT4. For
details, refer to the descriptions in this section.
9.1.6 "AND" Operation
Performs logic "AND" 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 AND operation of
two binary bits are shown in
Table 9.2 Logic "AND" Operation
.
