LE-8500X-SE No Wi-Fi connection
LE-8500XR-SE With Wi-Fi connection
LE-8500X-SE / LE-8500XR-SE is a communication analyzer that can measure and test the standards: "100BASE-T1", "10BASE-T1L", and "10BASE-T1S". This device also has an SPoE/PoDL measurement function, and the measured communication data and SPoE/PoDL power data can be automatically saved by adding GNSS (PPS) time-corrected timestamps to them to an external storage connected via USB 3.0. The recorded data can be checked on the spot by the analyzer's display, thus you can use it in a variety of situations for the development and evaluation of Single Pair Ethernet devices.
Compatible with 100BASE-T1, 10BASE-T1L, 10BASE-T1S measurements
The following measurement settings are available.
For 100BASE-T1, arbitrary Master/Slave settings can be made.
For 10BASE-T1L, it can automatically match the settings of the measurement target by auto-negotiation. In addition, it can perform measurements with arbitrary Master/Slave settings, Force settings, and Vpp settings. For 10BASE-T1S it can measure with multi-drop connections. Capturing is possible without interfering with the PLCA operation to be measured.
How to Connect

SPoE/PoDL measurement function and PSE diagnosis (pseudo PD) function
PoDL measurement can measure the power of Class 0 to 15. Additionally, for devices that perform SCCP communication, it can measure SCCP communication content. Since the shortest measurement cycle is 10 μS, it also can check SCCP communication in a graph.
The PSE diagnostic function uses a pseudo-PD inside the board to diagnose the operation of PSE equipment. In addition to class determination, this function can create a response to any PD SCCP to respond.
Can output test packets for network load tests
■ Outputs test packets at wire rate
If you select the packet generation function, you can output Ethernet packets of arbitrary test data from port A/B. Test data can be set in 16 transmission data tables, and the transfer rate can be adjusted by specifying IFG (transmission frame gap) for each table. It can be used for network load testing.
10BASE-T1S multidrop PLCA diagnostic function
The PLCA diagnostic function diagnoses which MAC address is using the PLCA's Local ID by connecting to a data line operating in multidrop.
Cable diagnostic function
The length and condition of a cable can be measured using the TDR method. It determines and displays whether the cable is open or short-circuited, allowing you to check the location of the failure. Since the NVP value can be adjusted, measurements can be made to suit the characteristics of the cable.
* Update firmware Version 1.10 or later
Signal quality display function
During the 100BASE-T1 or 10BASE-T1L link, you can measure the signal-to-noise ratio of the received signal and display the signal quality.
* Update firmware Version 1.10 or later

Timestamp which can be time-synchronized by GNSS (PPS) signal
In the case of a time stamp of a crystal oscillator with ±20ppm accuracy in general, there may have a time rag up to 1.7 seconds a day. By using the GNSS/GPS time synchronization function, accurate time stamps corrected in seconds can be added to the monitor data. Thus even when you monitor by using two analyzers two different points simultaneously where communication failures rarely occur while a long period of time, you can compare and verify the measurement data of two units based on the time stamp.

In addition, as the PPS signal for time synchronization can be output from the unit to which the GPS antenna is connected, by connecting it to the second analyzer with the SMA coaxial cable (sold separately), you can simultaneously measure by the two units with synchronized time stamps.
[ Simultaneous measurement by using PPS signal ]
Measurement targets can be expanded by replacing the measurement board.
By replacing the measurement board with the optional measurement boards (sold separately), it can be used as a analyzer for serial communication equivalent to LE-8500X-SE-RT (when using SB-R2TS1), Single Pair Ethernet, or CAN/High-speed analog signal.
