Background/Introduction This guide discusses using the Tektronix TDS 2012 Digital Storage Oscilloscopes to make simple voltage versus time measurements and perform/use elementary functions. Figure 1 shows the front panel of the oscilloscope. Digital storage oscilloscopes sample analog signals, store the values (and corresponding times), and display them on the screen. -

4/18 tds2012_oscilloscope_guide.doc Simple voltage measurement and display For the simplest case of a single self-triggering measurement, connect a P2200 passive probe to the CH1 BNC connector and the tip of the probe to the component/device whose voltage is to be measured. -
Page 5: Channel Menus
5/18 tds2012_oscilloscope_guide.doc Channel menus The yellow CH1 MENU and blue CH2 MENU buttons are used to cause the oscilloscope to either display or hide the signal from the corresponding channel (yellow trace for CH1 and blue trace for CH2). In addition, when the particular channel is selected, a softkey menu for that channel will be activated. -
Page 6: Set To Zero
6/18 tds2012_oscilloscope_guide.doc Set to zero Under the “HORIZONTAL” menu, the SET TO ZERO button sets the horizontal position (controlled by the horizontal position knob) to zero (center vertical axis), thus centering the signal horizontally. Help The oscilloscope has a Help system with topics that cover all the features of the oscilloscope. You can use the Help system to display several kinds of information: 1) general information about understanding and using the oscilloscope, 2) information about specific menus and controls, and 3) device about problems you may face while using an oscilloscope (e.g., reducing... -

Page 8: Save/Recall
8/18 tds2012_oscilloscope_guide.doc The + and - options will display the sum or difference of the two signals on the display. It is important to note that the sum or difference will be calculated using the visual signals on the display. This means that if one signal is displayed to a higher magnification level (i.e., different VOLTS/DIV setting) than the other, the result will not be a true sum or difference. -

9/18 tds2012_oscilloscope_guide.doc You can choose an FFT window to eliminate discontinuities that will disrupt your output. As shown in Table 3, there are three window choices. Table 3 FFT window options Problems occur when the oscilloscope acquires a time-domain waveform containing frequency components that are greater than the Nyquist frequency. -

10/18 tds2012_oscilloscope_guide.doc There are several options for eliminating aliasing: 1. Adjust the Sec/Div control to a faster setting. This will raise the Nyquist frequency and bring the FFT display within range of the aliases. 2. If you do not need to view frequencies components above 20 MHz, set the Bandwidth Limit option to On. -
