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 reects the real

value, not the attenuated level.

Procedure 1. Press the Channel key. CH1

2. Press the Probe repeatedly to select the

attenuation level.

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 inuence on the real signal; it only changes the

voltage scale on the display.
