    6.Demonstration 6.Demonstration Notice: The following is to take MSO7102T model as an example. Example 1: Measurement of Simple Signals The purpose of this example is to measure the frequency and peak-to-peak value of a given signal. Step1 Go to CH1 menu and Probe menu to set attenuation coefficient as 10X, turn the switch on the Probe to 10X as well.

    6.Demonstration the signal in conformity with the trigger conditions. If a signal reaches to the set trigger level, one sampling will be made and then displayed in the screen. With this function, any random occurrence can be captured easily. Taking the burst burr of larger amplitude for example, set the trigger level to the value just greater than the normal signal level, and then presses the RUN/STOP button and waits.
