To Specify Probe Attenuation Factor
Set the probe attenuation factor to match the type of the probe that you are using to
ensure correct vertical readouts.
Press the CH1 button on the front panel; then press the Probe softkey and turn the
Universal Knob to select the desired value and push the knob to confirm. The default
setup is 1X .
The current probe attenuation factor is displayed in the channel label at the right side of
the screen. You can also press the Probe softkey continuously to switch the probe
attenuation factor.
The table shows the probe attenuation factor

To Specify channel Input Impedance
The channel input impedance is 1MΩ.
●
Impedance setting to 1MΩ is for use with many passive probes and for general-
purpose measurements. The higher impedance minimizes the loading effect of the
oscilloscope on the device under test.
The current channel input impedance is displayed in the channel label at the right side of
the screen.
