LE-8500X/LE-8500XR is a handy-type communication-protocol-analyzer equipped with a measurement board that can simultaneously measure and test the power supply status of one PoE (Power over Ethernet) and two lines of Ethernet communication data on a line (from 10BASE-T to 1000BASE-T).
It can be widely used for diagnosis and testing of LAN networks and related devices by using the packet monitor function, packet generate (PG) function, statistical analysis function, PoE judgment 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 another measurement board (sold as an option), the communication interface to be measured can be expanded later, so they can be widely used from network systems to development testing and maintenance of embedded communication equipment.

You can check the setting items, monitoring example, and the user interface with the online demo.

Simultaneous measurement of the packets on two Ethernet channels and one PoE

top menu display

This model has 4 ethernet ports that support GbE measurement ability. It can simultaneously measure the packet flowing on two Ethernet channels - between ports A and B and between ports C and D. In addition, PoE power measurement between ports A and B is also supported and Ethernet packets and PoE power can be measured at the same time. Thus it is useful for the cases such as the checking of how the PoE for the PoE devices (PD) such as WEB cameras changes by a control-command packet transmission occurs.

There is also a delay time measurement function that can measure the reception time difference of the sent/received packets of each port, and a statistical analysis function that can check the tendency of communication traffic for each time zone.

You can measure the transfer rate of the target line for each time period. (Ver1.03 or later)

Outputs test packets at wire-rate from 2 channels at the same time

By using the packet generation function, you can output Ethernet packets of arbitrary test data from port C/D or from both ports at the same time. Test data can be set to 16 transmission data tables, and the transfer rate can be adjusted by specifying the IFG (transmission frame gap) for each table. It can be used for network load testing.

PoE / PoE + / PoE ++ judgment and long-time power recording

[ PoE measurement graph display ]
top menu display

This model has the PoE measurement function which supports the measurement of PoE / PoE + (IEEE802.3af/at) and new standard PoE ++ (IEEE802.3bt) for high power supply. In addition to continuously recording the power consumption, voltage, and current between the PSE power supply device and PD power receiving device for a long time, it can judge real-time PoE appropriateness such as power supply type (Alternative A / B, polarity) and display upper and lower limit voltage, a graph, dump screen.

*    It cannot be used when a current exceeding 720mA flows continuously on PoE++(IEEE802.3bt).

Cable Diagnostic Function

You can measure the length and condition of a LAN cable using the TDR method. Detects and displays disconnections, short circuits, and broken pairs in the LAN cable, 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

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.

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-RT (when using SB-R2TS1), Single Pair Ethernet, or CAN/High-speed analog signal.

While recording the measurement data in the capture memory, this unit can automatically save them as a communication log file of the specified size continuously for a long time into external storage such as USB memory to or SSD (up to 2TB). The auto-saved communication log file (# nnnnnnn.DT: n is a serial number in the order of saving) can be divided into multiple files of the specified size and saved, so from the time stamp of the file in the time zone when the communication failure occurred you can narrow down the communication logs of it by checking the their time stamp.

Autosave function

Communication log files can be imported to a PC while measurement.

Using "LE File Downloader lefiledownload (V1.04 or later)", you can import the communication log files saved in the storage device with the auto save function to your PC via LAN or Wi-Fi. Execute the auto-save on the analyzer set at the site, import the communication log file with the time stamp around the time when the communication failure occurred into the PC, convert it to Pcap/Pcapng format with "lepcapcvt", and then you can analyze it with Wireshark, etc.

* Update firmware Version 1.04 or later
