RATOC Systems Japan SPI/I2C Bus Analyzer
Model: REX-USB62
REX-USB62 is a protocol analyzer for analyzing and monitoring communications on the Serial Peripheral Interface (SPI) and Inter-Integrated Circuit (I²C) buses. It was developed by the Japanese company RATOC Systems.
This device is designed to connect to a computer via USB, turning the computer into a powerful analysis tool for electronics engineers and developers.
Analyzer Mode: Used for one-shot capture and detailed analysis.
Displays the time and data of the signals on the bus.
Helps search for specific communication events or errors using external triggers.
Monitor Mode: Used to collect and display data in real time (free-run capture).
Useful for observing the normal flow of communication without interruption.
Allows the user to view bus data as it occurs.
Target users:
Electronics engineers and hardware designers use it to debug communication between components on a circuit board.
Embedded software developers use to verify that the software on the microcontroller is communicating correctly with peripherals.
Electronics students and hobbyists can use it to learn and experiment with SPI and I²C protocols.
The REX-USB62 is a USB-based analyzer used to monitor and analyze communication on a computer's SPI or I2C bus. It acts as a tool for developers and engineers to capture, display, filter, and analyze data signals exchanged between a computer and a device on these serial communication buses.
Key functions and features
Bus monitoring: It can monitor and display the data flowing across SPI and I2C buses, either in a one-shot or free-running mode.
Data capture: Users can capture data based on external triggers or when specific data patterns are detected.
Data analysis: The software allows for displaying captured data, filtering it (for I2C only), searching for specific data, and saving the results.
Power supply: The device can provide a power supply (up to 100mA) to the target device and supports interface voltages of 1.8V, 2.5V, 3.3V, and 5.0V.
USB powered: It operates using power from a USB connection, meaning it doesn't require an AC adapter
