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.

directly rotate Wave Vertical
the vertical scale.
Press ωc to set the lower limit frequency. For setting methods, refer to
⚫
descriptions in "Parameter Setting Method".
Note:
The settable range of the lower limit frequency is related to the Math
sample rate (displayed at the bottom of the screen when the Math function is
enabled). The sample rate of the analog channel or the changes of the memory
depth can affect the Math sample rate.
Press More → 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 → Invert to enable or disable the inverted display function of the
