Page 156: Trigger Setup
Trigger Setup Trigger Setup This section contains concepts and procedures for setting up the oscilloscope to trigger on your signal. Triggering Concepts Trigger Event The trigger event establishes the time-reference point in the waveform record. All waveform record data is located in time with respect to that point.
Page 157 Trigger Setup Untriggered display Triggered display Trigger Modes The trigger mode determines how the instrument behaves in the absence of a trigger event: Normal trigger mode enables the instrument to acquire a waveform only when it is triggered. If no trigger occurs, the last waveform record acquired remains on the display.
Page 158 Trigger Setup You can also force the instrument to trigger by pushing the front-panel Force Trig button. Trigger Holdoff Adjust holdoff to obtain stable triggering when the instrument is triggering on undesired trigger events. Trigger holdoff can help stabilize triggering, since the oscilloscope does not recognize new triggers during the holdoff time.
Page 159 Trigger Setup Trigger Coupling Trigger coupling determines what part of the signal is passed to the trigger circuit. Edge triggering can use all available coupling types: DC, Low Frequency Rejection, High Frequency Rejection, and Noise Rejection. All other trigger types use DC coupling only.

Page 242: Using Fft
Analyze Waveform Data Using FFT An FFT breaks down signals into component frequencies, which the oscilloscope uses to display a graph of the frequency domain of a signal, as opposed to the oscilloscope’s standard time domain graph. You can match these frequencies with known system frequencies, such as system clocks, oscillators, or power supplies.

Use long record lengths to lower the noise relative to the signal and increase the frequency resolution. If desired, use the zoom feature along with the horizontal Position and Scale controls to magnify and position the FFT waveform.

Page 323: Capturing A Single-Shot Signal
Application Examples Capturing a Single-Shot Signal In this example, the reliability of a reed relay in a piece of equipment has been poor, and you need to investigate the problem. You suspect that the relay contacts arc when the relay opens. The fastest you can open and close the relay is about once per minute, so you need to capture the voltage across the relay as a single-shot acquisition.
Page 324 Application Examples 6. Push Slope and 7. Turn the Trigger Level knob to adjust the trigger level to a voltage midway between the open and closed voltages of the replay. 8. Push Single (single sequence). When the relay opens, the oscilloscope triggers and captures the event.
Page 325 Application Examples Optimizing the Acquisition The initial acquisition shows the relay contact beginning to open at the trigger point. This is followed by large spikes that indicate contact bounce and inductance in the circuit. The inductance can cause contact arcing and premature relay failure.
Page 326 Application Examples Using the Horizontal Zoom Function To take a close look at a particular point on the acquired waveform, use the horizontal zoom function. To look closely at the point where the relay contact ﬁrst begins to open: 1. Turn the Zoom knob. 2.
Page 327 Application Examples The ragged waveform and the inductive load in the circuit suggest that the relay contact may be arcing as it opens. MSO4000 and DPO4000 Series Oscilloscopes User Manual...
Page 328: Correlating Data With A Tla5000 Logic Analyzer
Digital waveforms from 4000 Series oscilloscopes cannot be transferred to the logic analyzer display. The iView External Oscilloscope Cable allows you to connect your logic analyzer to a Tektronix oscilloscope. This enables communication between the two instruments. For 4000 Series oscilloscopes, you also need a TEK-USB-488 adaptor. The Add External Oscilloscope wizard, which is available from the TLA application System menu, guides you through the process of connecting the iView cable between your logic analyzer and oscilloscope.
Page 329 Application Examples To do this: 1. Select Add iView External Oscilloscope from the logic analyzer System menu. MSO4000 and DPO4000 Series Oscilloscopes User Manual...

Application Examples 2. Select your model of oscilloscope. 3. Follow the on-screen instructions, and then click Next. 4. See your Tektronix Logic Analyzer documentation for more information on correlating data between your Tektronix oscilloscope and logic analyzer. Tracking Down Bus Anomalies In this example, you are testing your new I C circuit.
Page 331 Application Examples Basic Strategy First, you will display and acquire the bus signal by setting up the bus parameters and trigger. Then, you will search through each packet with the search/mark functions. NOTE. Triggering on I C, SPI, CAN, LIN, FlexRay, RS-232, RS-422, RS-485, UART, I S, Left Justiﬁed, Right Justiﬁed, and TDM bus signals requires use of an appropriate DPO4EMBD, DPO4AUTO, DPO4AUTOMAX, or DPO4COMP, DPO4AUDIO Serial Triggering and Analysis Module.
