20MHz (−3dB) low-pass filter. This function is
useful for cutting off high frequency noise to see
the clear waveform shape.
Procedure

Probe attenuation level and type
Background
The probe can be set to either voltage or current.
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 or current level on the display reflects the
real value, not the attenuated level.
Procedure
1. Press the Channel key.
