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.

• 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

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.

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.

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.

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.

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.

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.
