Page 59: Probe Compensation
Getting Started with TDS200 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 input attenuation circuit of the probe. You must balance these capacitive effects between the probe and oscilloscope.
Page 60 Getting Started with TDS200 Oscilloscopes Note: You must compensate a passive voltage attenuation probe every time you change a probe/channel connection on your oscilloscope. This ensures that the probe accurately transfers the signal from a signal source to the oscilloscope. The following procedure enables you to balance the capacitive and resistive effects of a probe and an oscilloscope by compensating the probe.

Using VERTICAL Controls After you set up your oscilloscope for VERTICAL controls, you can perform various procedures, such as switching the input coupling of a signal, modifying the vertical scale, and changing the vertical position of a waveform. Switching the Input Coupling Coupling is the method you use to connect an electrical signal from one device to another.
Page 112 Using VERTICAL Controls You can change the type of input coupling to view the various components of a signal. For example, you can use vertical AC coupling to view a repeating signal that is above 10 Hz and has a large DC offset. AC coupling allows you to view such signals without any special offset controls.
Page 113 Using VERTICAL Controls However, the ground reference arrow and the trigger level reference arrow at the left and right of the display, respectively, do not shift from their initial positions. 4. In the VERTICAL section, turn the Channel 1 VOLTS/DIV knob clockwise to set the CH 1 vertical scale readout at the bottom left corner of the oscilloscope display to be 50.0mV.
Page 114 Using VERTICAL Controls This happens because AC coupling is a high pass filter that blocks a component of the signal. 8. Turn the Channel 1 POSITION knob counter- clockwise to set the vertical position at -100.00 divs (-5.00V). Re-calibrate the probe for a square waveform.
Page 115 Using VERTICAL Controls VERTICAL Control MENU Buttons You use the various side-screen menu buttons of VERTICAL controls to select special functions, such as the input coupling for the signal, the bandwidth limit of the oscilloscope, and the probe attenuation factor. The next procedure demonstrates the steps to use the side- screen menu buttons of VERTICAL controls to modify the vertical scale of a waveform.
Page 116 Using VERTICAL Controls 2. Push the appropriate side-screen menu button to select Probe 10X for Channel 1. 3. Push the appropriate side-screen menu button to select BW Limit ON 20MHz. Limiting the bandwidth of the oscilloscope reduces high-frequency noise in the waveform. 4.

Page 142: Trigger Holdoff Controls
Using TRIGGER Controls Trigger Holdoff Controls Triggering a signal at the correct point is essential to ensure the proper display of a waveform. You can use the TRIGGER controls on the front panel to stabilize repeating signals, as well as to capture single-shot waveforms.
Page 143: Setting Up Trigger Controls
Using TRIGGER Controls Setting Up TRIGGER Controls Before you use the TRIGGER controls for operation exercises, you must ensure that the oscilloscope is set to its default setting. This procedure enables you to set the default settings required for procedures with TRIGGER controls. To set up a TDS200 oscilloscope for TRIGGER controls follow these steps: 1.
Page 144 Using TRIGGER Controls You will see a waveform similar to that shown in Figure 5.2. Figure 5.2: Pseudo random communications signal without holdoff Figure 5.2 shows the varying details of a pseudo random communications signal. However, observe that the displayed signal updates itself continuously in such a way that you cannot see a stable waveform display.
Page 145 Using TRIGGER Controls These can be an input signal from another channel, the oscilloscope power source, or an external input signal to the oscilloscope. You can also use trigger holdoff to stabilize a complex repeating waveform. Trigger holdoff is an adjustable period after a trigger, within which an oscilloscope cannot trigger again.
Page 146: Assigning Trigger Holdoff
Using TRIGGER Controls Assigning Trigger Holdoff The following procedure enables you to assign a holdoff time for the trigger generated by the PSEUDO RANDOM signal from pin 5 of the Training 1 signal board. This enables you to see a stable waveform display. Note: This procedure assumes that the oscilloscope retains the settings from the previous procedure.
Page 147 Using TRIGGER Controls You will see a waveform similar to that shown in Figure 5.4. Figure 5.4: Stable display of pseudo random communications signal by using trigger holdoff Observe that assigning a trigger holdoff time stabilizes the display of a repeating signal. You can also modify the horizontal scale of a displayed waveform by adjusting the sec/div setting.
Page 148: Assigning Trigger Holdoff With An Am Signal
Using TRIGGER Controls You can use the TRIGGER menu to assign a trigger holdoff for either edge or video triggering. In addition, you can assign a trigger holdoff when the oscilloscope is in the Normal or Auto trigger mode. It may be difficult to see a stable display for a repeating digital signal, such as a pseudo random signal, on an oscilloscope because edge transitions occur at many places within the waveform.
Page 149 Using TRIGGER Controls Figure 5.5 shows the updating overlay of the amplitude modulation region of an amplitude modulated (AM) signal. Figure 5.5: Complex AM signal without holdoff To observe a stable display of the amplitude modulation of a complex repeating signal, you must adjust the trigger level within the amplitude modulation region of the displayed waveform.
Page 150 Using TRIGGER Controls The next procedure enables you to analyze the amplitude modulation region of a complex repeating signal by assigning a trigger holdoff in the amplitude modulation region of the signal. To assign a trigger holdoff for an AM signal, follow these steps: 1.

You observe that the pseudo random signal on pin 5 is triggered by the CLK 20MHz signal from pin 2. You will see an Eye Diagram display similar to that shown in Figure 5.7.
Page 157: Selecting A Trigger Type
Using TRIGGER Controls As the EXT TRIG input on the TDS210 or TDS220 oscilloscope has a 10X probe connected to it, the trigger level is actually 10 times more than as shown on the display. You can further extend the external trigger level range of the TDS210 and TDS220 oscilloscopes.

Page 160: Selecting The Signal Coupling For A Trigger
Using TRIGGER Controls Selecting the Signal Coupling for a Trigger You can select the coupling type for a trigger when you choose edge triggering. You can choose to select AC, DC, Noise Reject, HF Reject, or LF Reject coupling for a trigger.
Page 161 Using TRIGGER Controls You will see a waveform similar to that shown in Figure 5.9. This trigger signal has a slower rise time and is the result of the low pass HF reject filter. This trigger selection rejects the high-speed components in the triggering signal.
Page 162 Using TRIGGER Controls On the other hand, Noise Reject coupling allows all components of a signal to pass to the trigger circuit, but increases the peak-to-peak signal required to trigger the signal. LF Reject is an AC coupled triggering mode that passes only the higher speed signal details above 50kHz sine wave bandwidth equivalent.
