⚫ Press More → Invert to enable or disable the inverted display function of the
waveform.
⚫ Press More → Label to set the label for math operation results. For details,
refer to descriptions in "Math Operation Label".
⚫ Press More → Color Grade to enable or disable the color grade display of the
operation results. When enabled, different colors are displayed on the screen to
indicate the times of data acquisition or acquisition probability.
⚫ Press More → Reset ColorGrade to clear the color grade display and display
the color grade again.
Diff
Calculates the discrete time derivative of the selected source. For example, you can
use differentiate to measure the instantaneous slope of a waveform.
Press Math → Math1 → Operator to select "Diff":
âš« Press Operation continuously to enable or disable the "Diff" operation function.
âš« Press SourceA, and rotate the multifunction knob to select the channel for
Source A. 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 Source A are CH1-CH4 and Ref1-Ref10.
Note: The source of Math2 can be CH1-CH4, Ref1-Ref10, or Math1; the source
of Math3 can be CH1-CH4, Ref1-Ref10, Math1, or Math2; the source of Math4
can be CH1-CH4, Ref1-Ref10, Math1, Math2, or Math3; only the channels that
have been enabled currently can be selected.
âš« Press Offset to set the vertical offset of the operation results. For setting
methods, refer to the descriptions in "Parameter Setting Method". You can
also directly rotate Wave Vertical
POSITION or enable the touch screen
to adjust the vertical offset.
âš« Press Scale to set the vertical scale of the operation results. For setting methods,
refer to the descriptions in "Parameter Setting Method". You can also
directly rotate Wave Vertical
SCALE or enable the touch screen to adjust
the vertical scale.
âš« Press AutoSetting to adjust the vertical scale and offset of the operation
results to an optimal value based on the current configuration, so as to better
observe.
⚫ Press More → Smooth to set the number of smoothing times in differential
operation. For setting methods, refer to descriptions in "Parameter Setting
Method".
Note: As the high-frequency component of waveform data has a great impact
on the differential operation, you need to adjust the parameter "Smooth" to a
larger value, so as to restore the low-frequency component.
