limit value will be displayed in the channel status label at the bottom of the screen, as
shown in the figure below.
TIP
Bandwidth limit can not only reduce the noise, but also can attenuate or eliminate the high
frequency components of the signal.

To Specify Input Impedance

This series oscilloscope provides 1 MΩ input impedance mode. In this mode, the
input impedance of the oscilloscope is very high, and the current flowed from the
circuit under test can be ignored.

To Invert a Waveform

Click or tap the channel status label at the bottom of the screen, and then the
Vertical menu is displayed. Then click or tap the Invert on/off switch to enable or
disable the waveform invert function.
When "ON" is selected, the channel label is as shown in the figure below.
When the Invert function is disabled, the waveform is displayed normally; when
enabled, the voltage values of the displayed waveform are inverted, as shown in the
figure below. Inverting a waveform also changes the result of math function,
waveform measurement, etc.
