Figure Q2.1 represents the true value of a noisy signal which is to be displayed on an

oscilloscope, in order to estimate the amplitude and period of the underlying sawtooth

waveform.

a. Suggest appropriate vertical axis and timebase settings for the oscilloscope.

b. How should the oscilloscope be triggered? Your answer should indicate where on the

waveform you plan to trigger (and why!) and how the oscilloscope can be configured

to achieve this.

c. Two oscilloscopes are available, a 500 MHz 3 GSPS model and a 100 MHz 500 MSPS

model.

i. Explain what these specifications mean.

ii. How will the displayed waveform differ between the two scopes?

iii. Which scope is better suited to the measurement described?
