Remember to use the proper safety precautions applicable to toxic, volatile solvents and flammablelubricants. You can refer to <strong>Naval</strong> <strong>Ships</strong>' Technical Manual (NSTM), Chapter 670, Stowage, Handling,and Disposal of Hazardous General Use Consumables, NAVSEA S9086-WK-STM-000.Using the OscilloscopeAn oscilloscope can be used for more than just studying the shape of a waveform. By looking atlissajous patterns and using an octopus, you can compare the phase and frequency relationship of twosignals and check electronic components in a circuit.LISSAJOUS PATTERNS.—The simplest lissajous patterns are produced by two sine waves of thesame frequency and amplitude being applied to the horizontal and vertical deflection voltage inputs of anoscilloscope. Figure 1-37 shows patterns for several common phase relationships. These can be used toestimate the approximate phase angle of the two signals being studied.1-126
Figure 1-37.—Lissajous patterns, showing the effects of phase relationships.Figure 1-38 will aid you in computing a phase angle if a more precise calculation is needed. We willuse the graticule on the oscilloscope, a ratio formula, and sine (sin) table to compute the angle.1-127
