Protocol Analyzer

Overview:
The LE-3500XR inherits all the functions of the previous models LE-3500/LE-3500R and is equipped with monitoring, simulation, and bit error rate testing capabilities required for communication analysis and testing.
The new design, featuring a touchscreen color LCD and lithium-ion battery, further enhances the performance of this dedicated computer-free analyzer. The color display makes it easy to grasp signal status and detailed notations such as communication errors in monitoring data. With both touchscreen and physical keyboard operation methods, users can swipe the touchscreen to browse large amounts of data on the screen and use either the on-screen or physical keyboard to input characters when editing transmission data for MANUAL simulation. Additionally, frequently used operations support shortcut keys.
The new housing with a built-in lithium-ion battery is significantly smaller and lighter than previous models, reducing the burden of equipment maintenance in the field and during business trips.
The LE-3500XR supports a wide range of communication protocols, including RS-232C serial communication, the reliability-focused RS-422/RS-485 bus or Modbus communication systems commonly used in the railway and aviation industries, I2C or SPI devices frequently used in embedded development, and in-vehicle communication networks such as CAN, LIN, and CXPI.
