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. The instrument continuously acquires and retains enough sample points to fill the pretrigger portion of the waveform record.
Trigger Setup 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. When the instrument recognizes a trigger event, it disables the trigger system until acquisition is complete. In addition, the trigger system remains disabled during the holdoff period that follows each acquisition.
Trigger Setup 1. Adjust the position (delay) time by rotating the Horizontal Position knob. 2. Turn horizontal SCALE to acquire the detail that you need around the position (delay) expansion point. The part of the record that occurs before the trigger is the pretrigger portion. The part that occurs after the trigger is the posttrigger portion. Pretrigger data can help you troubleshoot.
Trigger Setup Choosing a Trigger Type To select a trigger: 1. Push Trigger Menu. 2. Push Type to bring up the Trigger Type side menu. NOTE. The bus trigger in the MDO3000 Series works on parallel buses even without an application module. Using the bus trigger on other buses requires use of a MDO3AERO, MDO3AUDIO, MDO3AUTO, MDO3FLEX, MDO3COMP, MDO3EMBD, or MDO3USB application module.

If you are setting up a MIL-STD-1553 trigger and have made a Trigger On selection of Command, push RT Address on the lower menu to enter specific values of RT Address to trigger on. Push Command Word Details on the lower menu to enter the T/R bit value, Subaddress/Mode value, Word Count/Mode Code value, and Parity value.
Trigger Setup !=, <, >, >=, and <= operations. Triggering on identifier and data always matches the identifier and data selected by the user, with the data starting at the first byte. No rolling window is used. For FlexRay and Ethernet, triggering occurs when the user-selected data input matches the data and qualifier in the signal starting at the byte offset. Set the number of bytes to match the number of bytes of interest. Use the data qualifier to perform: =, !=, <, >, >=, and <= operations.
Trigger Setup Using Sequence Trigger (A (Main) and B (Delayed)) Combine an edge A Event (Main) trigger with the B Event (Delayed) trigger to capture more complex signals. After the A Event occurs, the trigger system looks for the B Event before triggering and displaying the waveform. A and B triggers can (and typically do) have separate sources. NOTE. You can select sequence triggering when you choose the slope type Falling or Rising — but not when you pick the slope type Both.
Trigger Setup Select the method for sequencing the B trigger after the A by pushing a side menu button. Time (a) 8 ns B Events 1 Set to Minimum 5. Set the other Sequence Trigger parameters in the related side and lower menus. B Trigger After Delay Time The A trigger arms the instrument.
