PSO2020 3.1 Set Oscilloscope Save Setup The oscilloscope software saves the current setup before you close the oscilloscope software. The oscilloscope recalls this setup the next time you run the software. You can use the “Save Setup” menu to permanently save up to several different setups. Load Setup The oscilloscope can recall the last setup before the oscilloscope software was running, any saved setups, or the factory setup. You can use the “Load Setup” menu to permanently recall a setup.
PSO2020 You can left click and drag the mouse on the green knob or the yellow knob to change the voltage. Invert The invert function turns the displayed waveform 180 degrees, with respect to the ground level. When the oscilloscope is triggered on the inverted signal, the trigger is also inverted. Click “Invert” in vertical.

PSO2020 from 4ns/div to 1hour/div. In the “Format” menu of the “Horizontal” menu, select the display mode to Y-T. 3.4 Set Trigger System Click “Trigger” in main menu. The trigger determines when the oscilloscope starts to acquire data and display a waveform. When a trigger is set up properly, it can convert unstable displays or blank screens into meaningful waveforms. If the oscilloscope wants to acquire a waveform, it collects enough data so that it can draw the waveform to the left of the trigger point.
PSO2020 Single: Acquire waveform when trigger occurred then stop Slope: Set the slope to Rising (+) or Falling (-). Rising: Trigger on rising edge Falling: Trigger on falling edge 3.5 Measure Signal 3.5.1 Cursor Click “Cursor” in main menu. This method allows you to take measurements by moving the cursors 1.

PSO2020 Chapter 4 Application Example Simple Measurement Capturing a Single-Shot Signal Taking Cursor Measurement User’s Manual 41
PSO2020 4.1 Simple Measurement To acquire and display a signal, please do the steps as follows: Connect signal to CH1 by using probe The oscilloscope set the vertical, horizontal, and triggers controls at the best status automatically. Also, you can adjust the controls to meet your measurement to optimize the waveform display. 1. To measure the frequency and “Vpp”, you can do these steps as follows: 2. Click the button, the frequency of the signal display on the bottom of the waveform interface. 3.
PSO2020 The results of measure display in Information output. 4.2 Capturing a Single-Shot Signal To capture a single event, it needs to gather some pre-test knowledge of the signal in order to set up the trigger level and slope correctly. For example, if the event is derived from 3.3V COMS logic, a trigger level of 1.2 or higher Volts should work on a rising edge. Do these steps as follows: 1. Set up the trigger in the Trigger Menu, or in the Trigger Setting window. 1) Adjust the Trigger Mode to Edge.
PSO2020 6) When the trigger conditions are met, data appears on the display representing the data points that the oscilloscope obtained with one acquisition. 4.3 Taking Cursor Measurements Use cursors to make time and amplitude measurements on a waveform quickly. Measure the Peak Frequency or Time of the First Sine Waveform Do these steps: 1. Click “Cursor->Source”, select CH1. 2. Click “Cursor->Type”, select Vertical. 3. Push left mouse button, and the vertical lines appear. 4.
PSO2020 5. Release the left mouse button, the voltage difference will be shown at the status bar. Note: Click “Cursor->Type”, select “Cross”, you can measure time and amplitude at one time.
