The oscilloscope laboratory exercise was to familiarize one with the operation and calibration of the oscilloscope in combination with other instrumentation, e.g. the signal generator, voltmeter, etc.. In doing so it was necessary to observe the RC-circuit's (resistor capacitor) rise and fall times to facillitate calibration or expectation of oscilloscope interaction since a composite result is the actual case as is in the example of rise time when it is zero, but shows as a finite time.
This produced familiarity with the operation of the various controls and their function. The other half of observing the oscilloscope with the phase difference modified to different levels on the "x-y" triggers was considerably more interesting, although fundamental operation and knowledge is necessary before preceeding to this section.
