Built-in Oscilloscope Trigger Makes Setup Easy

Isolate specific MIL-STD-1553 messages with the built-in oscilloscope trigger. Powerful error triggers identify areas to quickly pinpoint failure locations. Use the conditional address trigger to identify a faulty RT on the bus to reduce debug time.

Powerful Conditional Triggering

Apply powerful and flexible conditional triggering to completely isolate a specific RT Address, Sub Address Data Value, and Mode Code.

The Most Intuitive Decode

1553 TD uses color-coded overlays on various sections of the protocol for an easy-to-understand visual display. Depending on the timebase setting or the amount of zoom, the decode information is condensed or expanded to better assist in understanding events during short or long acquisitions. 1553 TD features both Transfer level and Word level decoding to offer the most flexibility to the debug process. The decode operation is fast—even with long acquisitions. The user can choose to decode into Hex, Binary, ASCII, or Decimal.

Flexible Triggering

The 1553 TD trigger can be configured at the transfer or word level to provide the right level of triggering. In addition, the error triggers are able to quickly locate the cause of protocol errors at either the word or transfer level.

Convenient Table Display Summarizes Results

Turn your oscilloscope into a protocol analyzer with the table display of protocol information. Custom configure the Table to display the information you want, and export Table data to an Excel file. Touch the message in the table and automatically zoom for detail. In all cases, the Table never obscures your waveform.

Search and Zoom

Search through a long record of decoded data by entering any of the 28 available search criteria by entering a value, or simply finding the next occurrence.

PROTObus MAG (Measure, Analysis, Graph)

 

The PROTObus MAG (Measure, Analysis, Graph) Serial Debug Toolkit is the basic building block upon which many other LeCroy serial trigger and decoder options can then be added. It significantly extends the trigger and decode functionalities of these other packages to by providing tools for more complete and faster validation and debugging of embedded designs. It provides the deepest level of insight possible.


Key Features
  • Additional 9 measurements to supplement serial decoders
  • Works with I2C, SPI, UART, RS-232, CAN, LIN, FlexRay, DigRF 3G, and MIL-STD-1553 Decode packages
  • Quickly setup and view Serial Encoded Data as Analog waveform representation
  • New Measurement setup window for easy configuration
  • Conditional filtering for accurate measurements

The PROTObus MAG Serial Debug Toolkit is the basic building block upon which many other LeCroy serial trigger and decoder options can then be added. It significantly extends the trigger and decode functionalities of these other packages to by providing tools for more complete and faster validation and debugging of embedded designs. It provides the deepest level of insight possible.

Data Extraction and Graphing tools

Extract data from the serial protocol message stream and use the track functions to graphically plot that data on the oscilloscope display. The digital data is used to create an analog waveform that can then be compared to other electrical signals.

Timing and Bus Measurements

Specific measurement parameters allow you to quickly and easily characterize your serial data system and make gateway measurements. Use the Message-Message parameter to find the time between two messages on the bus or the Message-Analog parameter to correlate bus traffic to an analog signal. Use LeCroy's measurement statistics and histicons to understand the range of measurements on the protocol bus.

Easy Measurement Setup

Easily configure the proper measurement with large descriptive icons, helpful descriptions, and measurement markers to make sure the measurement is made properly. Apply a filter to any measurement for more accurate results. Identify a specific ID or ID and Data using the powerful conditional setup for more accurate filtering.

Powerful Graphing Tools

The most powerful feature of the PROTObus MAG Serial Debug Toolkit is the ability to extract digital data from the serial data message using the Message to Value measurement. Then, by applying the Math operator, View Serial Encoded Data as Analog Waveform, the user can view a plot of the data values over time with an intuitive analog waveform representation — a view not available in any other product. Some examples of the usefulness of this capability are: viewing data from a temperature sensor or controller that is sent via an I2C or SPI bus; radio frequency I and Q modulated signal information sent via DigRF 3G; or rotational wheel speed information used by an anti-lock braking system (ABS) and sent via CAN. The ability to convert the embedded digital data in the serial data message to an analog value and view an analog waveform representation of the data is a powerful feature that makes the PROTObus MAG Serial Debug Toolkit a necessity for engineers debugging serial protocols.

Timing Measurements

PROTObus MAG also includes automated timing measurements useful for embedded design cause-effect validation, such as Message to Analog, Analog to Message, or Message to Message. These measurements provide the ability to rapidly and accurately validate embedded system operation, and then perform statistical analysis using LeCroy's powerful statistical histogram views and measurements. For instance, a serial data message sent by an embedded controller might initiate another signal or serial data message on the same or another embedded controller. By automating the timing measurement between these two events, and allowing rapid collection and analysis of large amounts of timing measurement data, embedded system validation can be more quickly and accurately performed, and the presence and cause of timing violations quickly located.

Bus Status Measurements

The bus status measurements Bus Load, Message Bitrate, and Number of Messages, give an overall status of the decode protocol to quickly learn if the bus is over utilized and to verify the bit rate matches expectations.

Setup is easy with the improved serial decode measurement setup tab.
  1. Choose the source
  2. Choose the measurement
  3. Select destination
  4. Then apply and configure
