LE-8500XR-RT  With Wi-Fi connection

The LE-8500X-RT/LE-8500XR-RT is a multi-protocol analyzer that can measure and test RS-232C, RS-530, RS-422/RS-485 and TTL level serial communication as a single unit. It can be widely used for the development and maintenance of serial interfaces of PC peripherals and FA devices, UART, SPI, I2C, etc. of embedded boards by using the monitor function, communication simulation function, bit error rate function, etc. according to the test situation. The model is equipped with a 7-inch wide-color LCD with a touch panel, thus you can check the measurement data immediately on-site without using a personal computer. You can log the data to a USB flash memory etc. via USB 3.0, thus you can analyze the data in detail after the measurement.
In addition, as the time stamps that are time-corrected with high accuracy by GNSS signals can be added to the monitor data by using an optional GPS antenna, by checking the time stamps you can compare and analyze the data measured simultaneously at two points for a long period of time to investigate a communication failure.
Furthermore, by replacing the standard measurement board with a LAN measurement board (sold separately), it can also be used for Ethernet networks. With just one unit, it can be used for many years from PC peripherals and embedded devices to communication fields where reliability is important, such as railways, aviation, and various production lines.

*1: To use the function, the optional accessories described in the brackets are required.
*2: This mode is used to capture all data in synchronization with clock edges.
*3: Transmission/reception data, idle time, time stamp, and line status items consume 4 bytes of memory at each capture.
*4: Part of the eMMC for storing measurement firmware is used.
*5: The maximum measurable speed is limited by the selected interface and protocol. When measuring a line with an effective transfer rate of 5Mbps or higher, it is supported by switching to high-speed mode. SPI: 30Mbps is supported by firmware version 1.08 or later.

In high-speed mode, all capture processing of communication data is performed by hardware, so data can be reliably recorded without capture loss even in high-speed communication with a high transfer rate. However, the high-speed mode is only compatible with the monitor function, MANUAL simulation function, logic analyzer function, and PULSGEN waveform editing output function, and cannot be used with the asynchronous PPP, character synchronous SYNC/BSC, Modbus, I2C, and BURST protocols. In addition, there is no monitor condition automatic setting, idle time, control line recording, timer/counter display, and available trigger conditions are only send/receive data match trigger, error trigger, and external signal trigger, and available trigger operation is measurement stop or external signal output.

*6: JIS (7bit data), EBCD, and Baudot are displayed in different characters depending on the shift-out (SO) and shift-in (SI) characters.
*7: An optional GPS antenna is required for GNSS synchronization. External PPS synchronization requires a device that outputs a PPS signal (such as another analyzer).
*8: This function supports only ASYNC, SYNC/BSC, HDLC/SDLC. Correct auto settings are impossible if the amount of communications data is small or communications data includes a large number of errors.
*9: If the input voltage exceeds ±15V, it will be clamped by the protection diode inside the unit.
*10: Only ASYNC mode and SYNC mode are available.
*11: Only ASYNC is available.
*12: Not all USB memories and USB3.0 interface SSDs are supported.
*13: The LE-PC800X has a product version and a light version with some functions limited. The light version can be downloaded for free from the LINEEYE website.
*14: A dedicated printer (SM4-31W) is required.
*15: Wi-Fi function is only with LE-8500XR-RT. It is available only in Japan, USA, Canada, and EU nations where the product is needed to be compliant with RE directive (2014/53/EU). When you want to use the analyzer in the other countries please select LE-8500X-RT.
*16: Measured under LINEEYE's measurement conditions.
