For example, when the attenuation ratio of the oscilloscope is 
set to 1X, the attenuation ratio of the high voltage probe is set 
to X200 and the vertical scale of the oscilloscope is 0.5V/div, 
the actual vertical scale is 200X0.5V/div=100V/div. When the 
input impedance of the oscilloscope is 50Ω, the actual vertical 
scale is 2X200X0.5V/div =200V/div. 
 
Note: When the attenuation ratio of the oscilloscope matches 
the attenuation ratio of the high voltage probe, the vertical 
scale displayed on the oscilloscope is the actual scale.
