Teledyne LeCroy WS510-EMB - Embedded System Bundle TD

The Embedded Bundle Trigger and Decode (TD) contains the capabilities included in the I2Cbus, SPIbus, and UART-RS232bus TD products. For more information on this product, please see the product pages for I2Cbus TD, SPIbus TD, and UART-RS232bus TD.

Highest Performance Triggers

Designed by people who know the standards, with the unique capabilities you want to isolate unusual events. Conditional data triggering permits maximum flexibility, and highly adaptable error frame triggering is available to isolate error conditions. Frame definition allows grouping of UART or SPI packets into message frames for customization.

The Best Serial Decoder

Decoded protocol information is color coded to specific portions of the serial data waveform and transparently overlaid for an intuitive, easy-to understand visual record. All decoded protocols are displayed in a single time-interleaved table. Touch a row in the interactive table to quickly zoom to a packet of interest and easily search through long records for specific protocol events using the built-in search feature.

Measure/Graph Tools for Validation Efficiency

Quickly validate cause and effect with automated timing measurements to or from an analog signal or another serial message. Make multiple measurements in a single long acquisition to quickly acquire statistics during corner-case testing. Serial (digital) data can be extracted to an analog value and graphed to monitor system performance over time, as if it was probed directly. Complete validation faster and gain better insight.

Eye Diagrams & Physical Layer

Rapidly display an eye diagram of your packetized low-speed serial data signal without additional setup time. Use eye parameters to quantify system performance and apply a standard or custom mask to identify anomalies. Mask failures can be indicated and can force the scope into Stop mode.

Every serial trigger we design exhibits deep knowledge of the standard. Most serial triggers work with digital (MSO) inputs, or the EXT input for the Clock line so as to conserve analog channels. Each serial trigger has some unique aspect for high performance, such as:

• I 2C trigger permits triggering on data in a specific location of an up to 2048 byte I 2C EEPROM read or write.
• UART or SPI bytes can be combined into a single "message frame" - trigger on custom protocols based on UART or SPI byte blocks.
• UART supports 9-bit "address" or "wakeup" mode triggering.
• CAN, CAN FD, LIN, FlexRay and MIL-STD-1553 permit conditional ID/Address triggering.
• CAN and CAN FD permit triggering symbolically using a DBC file.
• USB 2.0 and MIL-STD-1553 triggers permits complex transaction definition and triggering. 

Conditional DATA Setup

Every Teledyne LeCroy low-speed serial trigger that incorporates DATA trigger permits a conditional (<. <=, =, >, >=, <>, inside a range, outside a range) setup for the DATA condition. This is especially useful in situations where abnormal events should be monitored, such as when a temperature sensor transmitting via I2C exceeds a maximum temperature, or a CAN node broadcasts a low or high engine RPM or coolant pressure. Furthermore, data for triggering can be specifically isolated in very long byte streams to specific bit locations, even those which span data bytes.

Support for Many Proprietary Protocols

Many proprietary serial protocols make use of the common UART (single Data line) or USART (Clock and Data lines, e.g., SPI) byte structures, with multiple bytes grouped into proprietary protocol definitions. Our highly flexible UART byte and SPI format definitions accommodate nearly any customer need, and the UART or SPI bytes can be defined to be part of a single “message frame” through use of our Interframe Setup. Then, the trigger pattern setup can isolate any byte value, e.g., an ID, or a DATA string value, that is part of your proprietary protocol message definition.

Simply the Best Serial Decoder

Our serial decode, search and table tools work exactly the way you want. These tools are the industry standard for turning your oscilloscope into a protocol analyzer with fast and intuitive correlation of protocol data to the physical layer waveforms.

Intuitive, Color-Coded Overlays

A transparent overlay with color-coding for specific portions of each protocol and the entire message frame makes it easy to understand your serial data information. Unlike other solutions, with protocol decode information away from the signal, our solution correlates the waveform and the protocol decode directly on the display. As the acquisition length is expanded or shortened, the decode overlay will adjust to show you just the right amount of information.

I2C

More Trigger Choices

In addition to typical Start/Stop/ReStart, NoAck, Address and Address+Data triggers, Teledyne LeCroy provides triggering for EEPROM read/writes up to 2048 bytes long and for Frame Length. Address-based triggers permit an additional ACK condition (ACK present, NO ACK present, or DON’T CARE). and selection to include a R/W bit in a 7-bit trigger.

More Flexibility for Address-based Triggers

Address-based triggers permit an additional ACK condition (ACK present, NO ACK present, or DON’T CARE). and selection to define the transfer direction as a READ, WRITE or DON’T CARE (using R/W bit in a 7-bit trigger, or R/W Direction selection in a 10-bit trigger).

SPI

SPI Triggering When No Chip Select is Present

Most SPI triggers require that a Chip Select signal be present. However, simplified (single-master, single-slave) SPI (also referred to as SSPI or SIOP) has no Chip Select. Our solution still permits triggering on simplified SPI through use of an Interframe Setup time. In most cases, the AUTO default provides accurate results, but MANUAL selection is also available.

UART and RS232

9-bit "Address" or "Wakeup" Triggering

Most UART triggers assume a maximum of 8 data bits (excluding stop/start and parity bits) in a single byte. However, our solution supports 9-bit data bytes for situations in which a UART protocol is utilized for Address, Wakeup or other communication to another peripheral, preceding the normal serial data byte transmission.

Interframe Message Time Setup for Proprietary UART-based Protocols

UART byte-based serial data signals with proprietary formats are often used. Given the flexibility of the setup of our trigger and decoder, it is often possible to use the Interframe Message Time Setup to “packetize” consecutive bytes into one Message Frame, and then trigger on in serial data in a particular byte location in the complete multi-byte Frame. Then, the UART decoder may be used to decode information as a complete Frame instead of individual Bytes.
