Remember to use the proper safety precautions applicable to toxic, volatile solvents and flammable
lubricants. You can refer to Naval Ships' Technical Manual (NSTM), Chapter 670, Stowage, Handling,
and Disposal of Hazardous General Use Consumables, NAVSEA S9086-WK-STM-000.
Using the Oscilloscope
An oscilloscope can be used for more than just studying the shape of a waveform. By looking at
lissajous patterns and using an octopus, you can compare the phase and frequency relationship of two
signals and check electronic components in a circuit.
LISSAJOUS PATTERNS.—The simplest lissajous patterns are produced by two sine waves of the
same frequency and amplitude being applied to the horizontal and vertical deflection voltage inputs of an
oscilloscope. Figure 1-37 shows patterns for several common phase relationships. These can be used to
estimate the approximate phase angle of the two signals being studied.
