Presentation Transcript

Slide 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)

Slide 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

Slide 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

Slide 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

Slide 5:

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

Slide 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
