Demonstration Example 1: Measurement of Simple Signals Observe an unknown signal in the circuit, and display and measure rapidly the frequency and peak-to-peak value of the signal. Carry out the following operation steps for the rapid display of this signal: Set the probe menu attenuation coefficient as 10X and that of the switch in the probe switch as 10X.
  • Page 102 Example 2: Gain of the Amplifier in the Metering Circuit Set the probe menu attenuation coefficient as 10X and that of the switch in the probe as 10X. Connect the oscilloscope CH1 channel with the circuit signal input end and the CH2 channel to the output end. Operation Steps 1.
  • Page 103 The operation steps are as follows: 1. Set the probe menu attenuation coefficient to 10X and that of the switch in the probe to 10X. 2. Adjust the VOLTS/DIV and SEC/DIV knobs to set up a proper vertical and horizontal ranges for the signal to be observed.
  • Page 104 Example 4: Analyze the Details of a Signal Observe the Signal Containing Noises If the signal is interfered by the noise, the noise may cause a failure in the circuit. For the analyzing of the noise in detail, please operate the instrument according to the following steps: 1.
  • Page 105 Separate Noises from the Signal When analyze the wave form of a signal, you should remove the noise contained in it. For the reduction of the random noise in the oscilloscope display, please operate the instrument according to the following step: 1.
