SB-FE2

SB-FE2 is an expansion board for LE-8600X/LE-8500X series for LAN measurement (Ether CAT compatible). It can tap 10BASE-T/100BASE-TX lines with zero delay and capture LAN packets on two lines simultaneously with highly accurate time stamps. It is ideal for applications such as monitoring input/output packets between slave devices on EtherCAT lines, where the time constraints of LAN packets are strict, and measuring the time difference. In addition, it can continuously measure PoE (Power over Ethernet) power information on two lines simultaneously for long periods of time, so it is also possible to check the power trends of two PoE devices. It can be used not only during device development, but also for on-site investigations and failure analysis.

Compatible analyzers: LE-8600X series, LE-8500X series

●Zero-delay tap ideal for EtherCAT packet measurement, simultaneous measurement of two lines
●Two lines of PoE/PoE+/PoE++ pass/fail judgment, long-term recording, logging to CSV files
●High-precision time stamp with time synchronization using GNSS (PPS) signals
●Latency measurement function that can measure the time difference between receiving and sending packets
●Statistical analysis function that can check the trends of communication traffic by time period
●Automatic recording of communication logs to large-capacity external storage via USB3.0
●Saving PcapNG files that can be analyzed with Wireshark
●PC link via LAN, USB, or Wi-Fi(XR only) connection

The firmware is pre-installed, so you can use it as a standalone analyzer just by replacing the interface board.

Equipped with four LAN ports for measuring Ethernet. Ethernet packets flowing on the LAN cables connected between ports A and B and between ports C and D can be monitored with no delay. The tap (monitor connection) to the analyzer body does not delay the packets being measured. In addition, ports A and B and ports C and D are fail-safe taps, so the links between the measurement targets are maintained even if the analyzer is turned off.

□ It also has a delay time measurement function that can measure the time difference between receiving packets sent and received on each port, and a statistical analysis function that can check the trends of communication traffic by time period.

You can also measure the transfer rate of the target line for each time period.

Equipped with PoE measurement function compatible with PoE/PoE+/PoE++ (IEEE802.3af/at/bt) on A-B port and C-D port. It can continuously record power consumption, voltage, and current between PoE PSE power supply device and PD power receiving device for a long time, and can also judge the suitability of power supply type (Alternative A/B, polarity) and upper and lower limit voltage in real time, display graphs, and display dumps.

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.

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 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.

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.

While checking the screen image of the analyzer main unit on the PC, the analyzer can be operated remotely using the PC's keyboard and mouse. Gbit LAN and USB 3.0 high-speed links offer smooth operation, and the model with Wi-Fi "LE-8500XR" can be connected to a computer without a cable for remote control.

The analyzer is equipped with a file management function that can save, read, and delete measurement data, setting data, and screenshots into external storage such as USB memory and SDHC card. You can also save it directly as a PcapNG file that can be read by LAN protocol analysis software Wireshark.

By using the data file conversion software "lepcapcvt" (for conversion to Pcap/Pcapng format that can be read by Wireshark), you can convert the measurement data saved in USB memory etc. to Pcap/Pcapng format on your computer. With this software, you can also operate [RUN] (start measurement) and [STOP] (end measurement) of the analyzer linked via LAN (etc.), import the measurement data of the analyzer to the PC via LAN (etc.), and save it as a measurement file.

A specified range of measurement data can be converted to a text file and saved to a storage device by the analyzer without using the PC link software. By connecting a dedicated printer, continuous printing of a specified range of measurement data and hardcopy printing of screen display images are available.
