For a description of the signal from each pin of the Training 1 signal board, see Appendix A, Training 1 Signal Board: Signal Definitions, starting on page A-1.
Page 81: Probe Compensation
Getting Started With TDS3000 Oscilloscopes Probe Compensation When you attach a passive voltage attenuation probe to an oscilloscope, the capacitances of both the probe cable and the oscilloscope’s input combine. This combined capacitance must match the capacitance of the probe’s input attenuation circuit. You must balance these capacitive effects with respect to the probe and oscilloscope combination.
Page 82 Getting Started With TDS3000 Oscilloscopes The following procedure enables you to balance the capacitive elements of the CH1 and CH2 probes with an oscilloscope by compensating the probes. Note: This procedure assumes that the oscilloscope retains the settings from the previous procedure. To compensate the CH1 and CH2 probes, follow these steps: 1.
Page 83 Getting Started With TDS3000 Oscilloscopes 7. Turn the VERTICAL POSITION knob to position the CH1 waveform in the top half of the display. 8. In the VERTICAL section, push the CH2 button to re-activate the controls for Channel 2. 9. Turn the VERTICAL SCALE knob to set CH2 to 2.00V on the oscilloscope display.
Page 84 Getting Started With TDS3000 Oscilloscopes However, the waveforms could also have distorted corners. Such waveforms could be similar to the waveforms shown in Figure 1.20 or Figure 1.21. Figure 1.20: Undercompensated probe Figure 1.21: Overcompensated probe 1-70 TDS 3000 Series Oscilloscopes – Operator Training Kit...
Page 85 Getting Started With TDS3000 Oscilloscopes An undercompensated or overcompensated probe can cause errors in measurement, especially with respect to pulse rise or fall times. To compensate the probes correctly, you must use the probe adjustment tool provided with the probes. The probe adjustment tool resembles a small screwdriver.

Page 91: Operating Vertical Controls
Using VERTICAL Controls Operating VERTICAL Controls In this section, you will perform various procedures to modify a displayed waveform by using the VERTICAL section controls. Using VERTICAL Controls to Modify Acquisition and Display The waveform shown in Figure 2.2 appears to be a single waveform.
Page 92 Using VERTICAL Controls The following procedure enables you to use the VERTICAL controls to modify the acquisition and display of a waveform. Note: This procedure assumes that the oscilloscope retains the settings from the previous procedure. To affect the acquisition and display of a displayed waveform by using the VERTICAL controls, follow these steps: 1.
Page 93 Using VERTICAL Controls 3. In the ACQUIRE section, push the RUN/STOP button twice. This reacquires the signal and stops the acquisition again. 4. In the VERTICAL section, turn the POSITION knob to move the waveform one division below its current position.
Page 94 Using VERTICAL Controls You will see a waveform similar to that shown in Figure 2.3. Figure 2.3: Dimmed waveform display with stopped signal acquisition and shifted waveform 5. In the ACQUIRE section, push the RUN/STOP button to resume signal acquisition. The waveform appears dim because the oscilloscope display shows only the last sampled acquisition after the signal acquisition is stopped.
Page 95: Working With Channel Displays
Using VERTICAL Controls When you change the vertical position of the waveform, the oscilloscope displays the last waveform saved by the intensity graded display. Working with Channel Displays You can simultaneously view multiple waveforms on a TDS3000 oscilloscope. These include up to four waveforms from the input channels, four saved reference waveforms, and a math waveform.
Page 96 Using VERTICAL Controls Note: This procedure assumes that the oscilloscope retains the settings from the previous procedure. To activate all input channels, follow these steps: 1. In the VERTICAL section, push the MENU button. 2. In the VERTICAL section, push the CH2 button to display the blue CH2 waveform.
Page 97 Using VERTICAL Controls You will see a display similar to that shown in Figure 2.4. Figure 2.4: 4 Channel display You can select any waveform by pushing the appropriate channel button in the VERTICAL section. You can also remove the waveform from the display by selecting a waveform and then pushing the OFF button in the VERTICAL section.
Page 98: Switching The Input Coupling
Using VERTICAL Controls Switching the Input Coupling Coupling is used to connect an electrical signal from one device to another. An example of coupling is connecting the Training 1 signal board to a TDS3000 oscilloscope. A TDS3000 oscilloscope allows you to select AC, DC, or ground coupling.
Page 99 Using VERTICAL Controls 4. Push the appropriate side-screen menu button to select AC. Note that the triggering for the signal stops and the waveform shifts down. The waveform shifts down because AC coupling blocks the DC component of the signal. However, the auto baseline trigger causes an untriggered waveform to appear on the oscilloscope display.
Page 100 Using VERTICAL Controls You will see a waveform similar to that shown in Figure 2.5. Figure 2.5: Modified input coupling Notice that the general purpose knob adjusts the volts/div scale with a very fine resolution. In addition, when you vary the size of the waveform on the oscilloscope display, the trigger level moves up and down with the waveform.
Page 101: Using Vertical Offset Controls
Using VERTICAL Controls Using Vertical Offset Controls At times, you may need to look at high amplitude signals or small signal details at very high resolutions. You can view such signal details by using the vertical Offset control. The following procedure enables you to change the vertical expansion reference with respect to the waveform by using the vertical Offset control.
Page 102 Using VERTICAL Controls 2. At the top of the front panel, push the SAVE/RECALL menu button. 3. Push the appropriate bottom-screen menu button to select Recall Factory Setup. 4. Push the appropriate side-screen menu button to select OK Confirm Factory Init. 5.

Using HORIZONTAL Controls Operating HORIZONTAL Controls The HORIZONTAL control section has two knobs, the SCALE knob and the POSITION knob. SCALE knob The HORIZONTAL SCALE knob is used to adjust the horizontal scale factor of a selected waveform. The horizontal scale of a waveform is measured in seconds/division.
Page 117: Affecting The Acquisition And Display Of A Waveform
Using HORIZONTAL Controls When you push the COARSE button on the top of the front panel, you can make adjustments with larger increments using the POSITION knob. After setting up a TDS3000 oscilloscope for HORIZONTAL controls, you can begin the procedures to modify a displayed waveform and take measurements.
Page 118 Using HORIZONTAL Controls The following procedure demonstrates the steps to select a portion of a displayed waveform by using the HORIZONTAL POSITION knob. Note: This procedure assumes that the oscilloscope retains the settings from the previous procedure. To change the horizontal position of a waveform, follow these steps: 1.
