Description
To obstruct DC component
of input signal.
To cut off input signals by AC
and DC components of input
signals.
To limit band width to 20MHz
so as to reduce display noise.
Full band width
To set vertical deflection
coefficient for coarse tuning
by 1-2-5 system. To refine
within setup scope of coarse
tuning for fine tuning so as to
improve vertical resolution.
To select one value according
to probe attenuation
coefficient to keep correct
vertical deflection coefficient.
There are totally 4 kinds,
namely, 1 , 10 , 100
and 1000 .
To realize reverse direction
function for waveform;
To display waveform normally.
