The Most Intuitive Decode
Advanced software algorithms deconstruct the waveform into protocol information, then overlay the decoded data on the waveform. Decode information condenses or expands depending on the timebase/zoom ratio setting, so understanding messages is easy. Various sections of the protocol are color-coded to make it easy to understand, especially for users new to I2C, SPI, UART, and RS-232 serial data. The decode operation is fast-even with long acquisitions. The user can choose to decode into Hex, Binary, or ASCII formats.
Teledyne LeCroy’s decode algorithms allow the CLOCK signal to be input to the external channel, which saves valuable channels for other signals. Or, if the CLOCK signal is input to a channel, it can be turned OFF as desired to reduce display clutter.
Powerful Conditional Data Triggering
Completely isolate specific I2C, SPI, UART, or RS-232 message events for better understanding and debug. Use a conditional DATA trigger to select a range of DATA values to trigger on, not just a single DATA value. Oftentimes, I2C utilizes DATA bytes to specify sub-addresses for accessing memory locations in EEPROMs. Conditional DATA trigger allows triggering on a range of DATA bytes that correspond to reads or writes to specific sub-address memory blocks in the EEPROM. It can also aid in monitoring DATA outputs from I2C-based sensors, such as analog-to-digital converters, and triggering when DATA is outside a safe operating range. In both cases, verifying proper operation becomes a simple task. Of course, all the basic I2C and SPI triggering capability you would expect is also included.
Full UART and RS-232 Capability and Customization
Complete support for any configuration of UART and standard RS-232. Generic UART is commonly used as the backbone for proprietary protocols, and the flexible setup configuration allows definition to meet your exact need.
Powerful Triggering, Intuitive Decoding
Flexible Triggering
I2C, SPI, and UART all have special use cases and the Teledyne LeCroy Trigger and Decode solutions address these cases. The I2C trigger can be configured for 7 or 10-bit addressing with out without inclusion of the R/W bit. The SPI trigger can be configured for a range of CPOL and CPHA settings as well as the Simplified SPI protocol. With the UART trigger 8 and 9-bit (8+1) formats are supported.
