Introduction :
Cathode Ray Tube (CRT) :
Electron gun
Heating element
Cathode
Control grid
Pre-accelerating and accelerating anode:
Focusing anode
Deflecting plates
Vertical deflecting plates or Y-plates
Horizontal deflecting plates or X-plates:
Measurement of voltages and Currents
Measurement of Phase
Measurement of Frequency :
The frequency of the signal can be given by using following formula,
where,
fy = unknown frequency
fx = known frequency
also,
where, fy = frequency of signal applied to Y-plates
fx = frequency of signal applied to X-plates
