RIGOL
Press 1 to open the setting menu of CH1. Then, press Impedance continuously to
select the input impedance of the oscilloscope. If you select "50 Ω", the channel
status label at the bottom of the screen will display the icon
Note:
After the oscilloscope recognizes the probe automatically, the input impedance

will also be auto recognized. You do not have to set it manually.
The setting of the input impedance will affect the ranges of channel vertical

scale and offset.
Waveform Invert
Press 1 to open the setting menu of CH1. Then, press Invert continuously to enable
or disable the waveform invert. When enabled, the channel label is displayed, as
shown in the following figure.
When disabled, the waveform is displayed normally; when enabled, the voltage
values of the displayed waveform are inverted (as shown in Figure 2-1). Enabling the
waveform invert will also change the result of math function and waveform
measurement.
(a) "Invert" Off
Note:
When the waveform invert is enabled, the trigger edge or the trigger polarity
will change (e.g. Edge trigger, Pulse trigger, or Slope trigger).
To Set the Probe
The analog channel of this oscilloscope not only supports the common passive probe,
but also the active probe. It can automatically recognize the currently connected
probe type and its probe ratio. For detailed technical information of the probes,
