To Specify Probe Attenuation Factor
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 matching gives you the most accurate measurements
because reflections are minimized along the signal path.
Impedance setting to 1M
Ω
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.
Impedance setting to 50
Ω
matches 50 ohm cables commonly used in making high
frequency measurements, and 50 ohm active probes.
Press the CH1 button on the front panel; then press the Impedance softkey to select the
desired impedance.
The current channel input impedance is displayed in the channel label at the right side of
the screen.
To Specify Amplitude Unit
Select the amplitude display unit for the current channel. The available units are V and A .
When the unit is changed, the unit displayed in the channel label will change accordingly.
1. Press CH1 button on the front panel to enter the CH1 function menu.
2. Press the
Next Page
softkey to enter the second page of the CH1 function menu.
3. Press the Unit softkey to select the desired unit V or A .

The default setup is V.
