Please press [F2] to set band width limitation to ON
for great attenuation of high-frequency component
and noise of more than 20MHz contained by
measured signals. Waveform display is also shown
in following figure.

It has to set probe attenuation coefficient in
operation menu of channel to coordinate with
attenuation coefficient setup of probe. Probe
coefficient in channel menu shall be set to 10× if
probe attenuation coefficient is 10:1. It has to
analogize to guarantee correct voltage.
Volt/grid gears of vertical deflection coefficient can
be divided into coarse tuning and fine tuning.
Please refer to following figure for setup and
vertical gear when using 10:1 probe.
