9.Demonstration 9. Demonstration Example 1: Measurement a Simple Signal The purpose of this example is to display an unknown signal in the circuit, and measure the frequency and peak-to-peak voltage of the signal. 1. Carry out the following operation steps for the rapid display of this signal: (1) Set the probe menu attenuation coefficient as 10X and that of the switch in the probe switch as 10X (see "How to Set the Probe Attenuation Coefficient" on P12).
9.Demonstration Figure 9-1 Measure period and frequency value for a given signal Example 2: Gain of a Amplifier in a Metering Circuit The purpose of this example is to work out the Gain of an Amplifier in a Metering Circuit. First we use Oscilloscope to measure the amplitude of input signal and output signal from the circuit, then to work out the Gain by using given formulas.
9.Demonstration Gain = Output Signal / Input signal Gain (db) = 20×log (gain) Figure 9-2 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.
9.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.
9.Demonstration (1) Push the Acquire button to display the Acquire menu. (2) Select Acqu Mode in the bottom menu. (3) Select Peak Detect in the right menu. 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 9-4).
9.Demonstration Figure 9-5 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. This example takes you step by step to check out the phase change of the signal after it passes a specified circuit.
9.Demonstration (8) With the elliptical oscillogram method adopted, observe and calculate the phase difference (see Figure 9-6). The signal must be centered and kept in the horizontal direction. Figure 9-6 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. As a result, the phase difference angle can be obtained, namely, q =± arcsin (A/B) or ± arcsin (C/D).
9.Demonstration (3) In the left menu, select Video as the mode. (4) Select Source in the bottom menu. Select CH1 in the right menu. (5) Select Modu in the bottom menu. Select NTSC in the right menu. (6) Select Sync in the bottom menu. Select Field in the right menu. (7) Turn the Vertical Scale, Vertical Position and Horizontal Scale knobs to obtain a proper waveform display (see Figure 9-7).
