18.1 Automatic Setting
Automatic settings will choose appropriate time base scale, amplitude scale and trigger parameter
according to the input signal so that the waveform will automatically display on the screen. Press the AUTO
key to enable automatic settings.
Automatic setting only applies to the following conditions:
a. Automatic setting is only suitable for simple single frequency signal. It is impossible to achieve effective
automatic setting for complex combination waves.
b. The measured signal frequency is not less than 20 Hz, and the amplitude is not less than 20 mVpp; the
duty cycle of square wave is greater than 5%.
18.2
Run/Stop
Use the RUN/STOP key on the front panel to set. When press this key and the green light is on, it indicates
the RUN state. If the red light is on after the key is pressed, it is the STOP state.
In the running state, the oscilloscope is continuously acquiring waveform and the upper part of the screen
shows “AUTO”; in the stop state, the oscilloscope stops the acquisition and the upper part of the screen
shows “STOP”. Press the RUN/STOP key to switch the waveform sampling between the run and stop states.
18.3 CLEAR
Use the CLEAR key on the front panel to set. Press this key to clear the recalled reference waveform on the
screen.
18.4 Factory Setting
Press the DEFAULT key on the front panel, the oscilloscope can quickly restore to factory setting.
MSO/UPO2000 series digital phosphor oscilloscope factory settings are as shown in Table 18-1.
