Beagle I2C/SPI Protocol Analyzer
TP320121
The versatile Beagle™ I2C/SPI Protocol Analyzer is the ideal tool for the embedded engineer developing an I2C or SPI based product. The Beagle I2C/SPI analyzer provides a high performance bus monitoring solution in a small, portable package perfect for in the field and in the lab.
- Non-intrusively monitor I2C up to 4 MHz
- Non-intrusively monitor SPI up to 24 MHz
- Non-intrusively monitor MDIO up to 2.5 MHz (Clause 22 and Clause 45)
- Bit-level timing down to 20 ns resolution
- Real-time data capture and display – Watch I2C and SPI packets as they occur on the bus
- View I2C and SPI protocol-level decoded data packets and I2C- and SPI-specific error code values
- Nearly limitless capture – Captured data is streamed via High-speed USB directly to your computer
- Fully Windows, Linux, and Mac OS X compatible
† Actual SPI capture performance is dependent on CPU speed and SPI bus throughput. 24 MHz SPI capture has been tested for typical applications (e.g., captures of a few hundred SPI packets). Depending on user configuration, the maximum achievable capture throughput for continuous streaming applications may be less than 24 MHz.
‡ MDIO monitoring is available in API and Data Center Software v2.20.
