Selecting the probe attenuation level

Background

A signal probe has an attenuation switch to lower
the original DUT signal level to the oscilloscope
input range, if necessary. The probe attenuation
selection adjusts the vertical scale so that the
voltage level on the display reflects the real value,
not the attenuated level.

Procedure

1. Press the Channel key.

CH 1

2. Press Probe repeatedly to

select the attenuation level.

Probe

x1

3. The voltage scale in the channel indicator

changes accordingly. There is no change in the
waveform shape.

Range

x1, x10, x100

Note

The attenuation factor adds no influence on the
real signal; it only changes the voltage scale on the
display.
