  • Trigger on all critical elements of serial buses
  • Decode all critical elements of each message (no more counting 1s and 0s)
  • Search through long acquisitions using user-defined criteria to find specific messages
  • Search mark table provides tabular view of events found during automated searches
  • Export search mark table data to .csv files
  • Event table shows decoded serial bus activity in tabular, timestamped format for quick summary of system activity
  • Export event table data to .csv files
  • For use with MSO/DPO3000 Series

The Tektronix DPO3AERO Military and Aerospace Serial Triggering and Analysis Module for MSO/DPO3000 Series enables triggering on packet-level information on MIL-STD-1553 buses as well as analytical tools such as digital views of the signal, bus views, packet decoding, search tools, and packet decode tables with time-stamp information.

Application modules have licenses which can be transferred between an application module and an oscilloscope. The Tektronix DPO3AERO's license maybe contained in the module; it can be moved from one instrument to another. Or, the license can be contained in the oscilloscope, allowing the module to be removed and stored for safekeeping. The license can also be transferred back to the module for use in another DPO3000 and MSO3000 oscilloscope. Transferring the license to an oscilloscope and removing the Tektronix DPO3AERO module permits the simultaneous use of more than two applications.

Serial Triggering and Analysis Application Modules

On a serial bus, a single signal often includes address, control, data, and clock information. This can make isolating events of interest difficult. The Serial Application modules for the DPO3000 and MSO3000 Series transform the oscilloscope into a robust tool for debugging serial buses with automatic trigger, decode, and search for MIL-STD-1553.

Serial Triggering

Trigger on packet content such as start of packet, specific addresses, specific data content, unique identifiers, etc. on MIL-STD-1553 serial interfaces.

Bus Display

Provides a higher-level, combined view of the individual signals (clock, data, chip enable, etc.) that make up your bus, making it easy to identify where packets begin and end and identifying sub-packet components such as address, data, identifier, CRC, etc.

Bus Decoding

Once you have set up a bus, the oscilloscope will decode each packet on the bus, and display the value in hex, binary and decimal.


Serial triggering is very useful for isolating the event of interest. In the past, users had to manually scroll through the waveform counting and converting bits and looking for what caused the event. With a Serial Application module, you can enable the oscilloscope to automatically search through the acquired data for user-defined criteria including serial packet content. Each occurrence is highlighted by a search mark. Rapid navigation between marks is as simple as pressing the Previous and Next buttons on the oscilloscope front panel. The Search Mark table provides a tabular view of all events found during an automated search. The search mark data can be exported to a .csv file.

Event Table

In addition to seeing decoded packet data on the bus waveform itself, you can view all captured packets in a tabular view much like you would see in a software listing. Packets are time stamped and listed consecutively with columns for each component (Address, Data, etc.).
