Exercise 1: You will be learning to use a Rigol D51052E oscilloscope in the lab. Watch the video Introduction to the D51052E Oscilloscope carefully, then complete the multiple- choice quiz before your next lab session for additional marks. 1. Where is the ON button on the Rigol D51052E? a. 0n the right side of the top panel, b. 0n the left side ofthe top panel, c. In the middle of the left side panel, d. In the middle of the back panel. 2. Which of these can an oscilloscope do that a digital multimeter can't do? a. Show us voltages that vary rapidly with time. b. Measure DC voltage. c. Measure AC voltage. cl. Nothing. 3. When you press the CH1 button the first time, a. The CH1 menu appears, b. The CH2 menu appears, c. Nothing unless a signal is connected to CH1, d. The CH1 menu disappears. 4. What does the small 1 in an arrow at the side of the screen show? a. The lowest voltage of the CH1 signal b. The highest voltage of the CH1 signal c. The zero voltage of the CH1 signal d. The zero voltage of the CH2 signal. 5. The voltage scale is displayed in what area of the screen? a. Top left b. Top right c. Bottom right d. Bottom left 6. The control to change the number of seconds per division displayed is a. The smaller dial at the top of the VERTICAL section of the user interface b. The larger dial at the bottom ofthe HORIZONTAL section of the user interface c. The smaller dial at the top of the HORIZONTAL section of the user interface d. The larger dial at the bottom of the VERTICAL section of the user interface 7. If you're not sure what voltage and time scales your signal requires, you can get a good first estimate by pressing the a. Run/Stop button b. Auto button c. Measure button cl. Utility button Exercise 2: When it comes to oscilloscopes, one of the least understood concepts is oscilloscope triggering. Triggering is the way the oscilloscope synchronises the diSplayed waveform with the input signal to obtain a stable display. Watch the first five minutes of the video Oscilloscope triggering carefully to get a better understanding of triggering, then answer the next three questions. (You can watch the entire video if you like to get an even better understanding of triggering.) 8. What is triggering? a. Allowing the oscilloscope to "free-run" so the display is not stable. b. The condition where the oscilloscope can sample the input and display a stable waveform. c. Moving the waveform up or down, or side to side to try to get a Stable display. cl. Adjusting the input signal to try to get a stable display. 9. Where, on the display, does a Digital Storage Oscilloscope trigger? a. At the Trigger Point, indicated by the I symbol, usually set in the middle. b. At the extreme left of the displayjust like the older Cathode Ray Oscilloscopes. c. At the extreme right of the display so the waveform starts again. d. It doesn't matter, triggering is not important. 10. What does the trigger level control do? a. It adjusts the Vertical Position of the waveform. b. It adjusts the Horizontal Position of the waveform. c. It makes the waveform larger or smaller. :1. It sets the level at which the displayed waveform will cross the centre vertical line on the display
