How to Set the Probe Attenuation Coefficient
The probe has several attenuation coefficients, which will influence the vertical scale
factor of the oscilloscope.
To change or check the probe attenuation coefficient in the menu of oscilloscope:
(1) Push the function menu button of the used channels (CH1 or CH2 button).
(2) Select Probe in the right menu; turn the M knob to select the proper value in the
left menu corresponding to the probe.
This setting will be valid all the time before it is changed again.
Caution:
The default attenuation coefficient of the probe on the instrument is preset to
10X.
Make sure that the set value of the attenuation switch in the probe is the
same as the menu selec
tion of the probe attenuation coefficient in the
oscilloscope.
The set values of the probe switch are 1X and 10X (see Figure 3-8).
Figure 3-8 Attenuation Switch
Caution:
When
the attenuation switch is set to 1X, the probe will limit the bandwidth
of the oscilloscope in 5MHz. To use the full bandwidth of the oscilloscope,
the switch must be set to 10X.
