CONFIGURATION

Limiting the waveform bandwidth
Background
Bandwidth limitation puts the input signal into a
20MHz (−3dB) low-pass filter. This function is
useful for cutting off high frequency noise to see
the clear waveform shape.
Procedure
1. Press the Channel key.

2. Press BW Limit to turn on or
off the limitation. When
turned on, the BW indicator
appears next to the Channel
indicator in the display.

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.

2. Press Probe repeatedly to
select the attenuation level.
3. Use the variable knob to
edit the voltage or current
attenuation.
VARIABL
4. 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.
