    6.Demonstration Gain = Output Signal / Input signal Gain (db) = 20×log (gain) Figure 6-2 Waveform of Gain Measurement Example 3: Capturing a Single Signal It's quite easy to use Digital Oscilloscope to capture non-periodic signal, such as a pulse and burr etc. But the common problem is how to set up a trigger if you have no knowledge of the signal? For example, if the pulse is the logic signal of a TTL level, the trigger level should be set to 2 volts and the trigger edge be set as the rising edge trigger.

    6.Demonstration (9) Select Coupling in the bottom menu. Select DC in the right menu. (10) In the bottom menu, select Slope as (rising). (11) Turn the Trigger Level knob and adjust the trigger level to the roughly 50% of the signal to be measured. (12) Check the Trigger State Indicator on the top of the screen, if it is not Ready, push down the Run/Stop button and start acquiring, wait for trigger to happen.

The signal displayed on the screen containing some noise, by turning on Peak Detect function and changing time base to slow down the incoming signal, any peaks or burr would be detected by the function (see Figure 6-4).

    6.Demonstration Figure 6-5 Reduce Noise level by using Average function Example 5: Application of X-Y Function Examine the Phase Difference between Signals of two Channels Example: Test the phase change of the signal after it passes through a circuit network. X-Y mode is a very useful when examining the Phase shift of two related signals.

    6.Demonstration (8) With the elliptical oscillogram method adopted, observe and calculate the phase difference (see Figure 6-6). The signal must be centered and kept in the horizontal direction. Figure 6-6 Lissajous Graph Based on the expression sin (q) =A/B or C/D, thereinto, q is the phase difference angle, and the definitions of A, B, C, and D are shown as the graph above.
