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. 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"...

  • Page 98 7.Demonstration Example 4: Analyze the Details of a Signal Noise is very common inside most of the electronic signal. To find out what's inside the noise and reduce the level of noise is very important function our oscilloscope is capable to offer. Noise Analysis The level of noise sometime indicates a failure of electronic circuit.

(3) Press the F3 button, turn the M knob and observe the waveform obtained from averaging the waveforms of different average number. User would see a much reduced random noise level and make it easy to see more details of the signal itself.
