Question 5
- Arrange the listed tools under the following headings: (i)Hand tools; (ii)Measuring instruments; (iii)Fault tracing equipment.
- State the function of each of the following controls in a Cathode Ray Oscilloscope: (i)intensity control; (ii)trigger level control.
A – Logic probe F – Screw driver
B – TV analyzer G – Ohmmeter
C - Signal tracer H – Voltmeter
D – Soldering gun I – Soldering flux
E – Slide cutters J – Multimeter

(b) (i) Intensity control: - used to vary the beam and hence adjust the brightness of the trace.
- used to control the luminance intensity of the trace.
(ii) Trigger level control: used to set the point on the signal waveform at which the time-
basegenerator is triggered and starts its sweep to display waveform.
