A TWO CHANNEL ANALOGUE CATHODE RAY OSCILLOSCOPE

1
A TWO CHANNEL ANALOGUE CATHODE RAY OSCILLOSCOPE
Intensity and focus controls are adjusted to
provide a sharp display Input to channel 1(BNC
connector) Input to channel 2 (BNC connector)
2
HORIZONTAL CONTROLS

• The main horizontal control is called the time
  base
• It adjust the time/division of the display
• The position control moves displayed waveforms
  horizontally

3
VERTICAL CONTROLS

• The main control adjusts the volts/division of
  the display
• The position control moves displayed waveforms
  vertically
• The input signal can be DC or AC coupled

4
TRIGGER CONTROLS

• The trigger level control adjusts the displayed
  waveform until it becomes stationary
• The coupling switch is normally left in the auto
  mode
• The source switch is moved to the input channel
  being used

TIME MEASUREMENTS
Example 5ms/div is selected on the TIME/DIV
SWITCH two cycles of a
sinusoidal waveform is displayed.
a cycle is completed in 5 divisions The period
is calculated by 5ms x 5div 25ms
6
VOLTAGE MEASUREMENTS
Example 2 volts/div is selected on the VOLTS/DIV
SWITCH from the positive peak
to the negative peak there are 6
divisions The amplitude is calculated by 2V x
6div 12Vpp
