The LE-580FX is a LAN analyzer that connects to a PC's USB2.0 port. In TAP mode, you can capture full duplex data on 10/ 100Base-TX and transmit to the PC at 480Mbps via the USB2.0 interface. In PG mode, you can generate test packets at up to 100Mbps line rate.

Use LE-580FX for :
• (1) Checking LAN protocols and data in the test devices.
• (2) Checking and analyzing traffic.
• (3) Providing statistical information, such as error rate etc.
• (4) Generate test packets for network test.
• (5) Measuring QoS, such as latency etc.
• (6) Studying network communication protocols.

Compact and light weight analyzer is easy to carry in you bag with the notebook PC.

TAP mode captures full-duplex data on PortA/ PortB, and transmits to PC via USB2.0 port. Captured data can be displayed on PC.

Time Stamp For Time Analysis

Add time stamp every time receiving data frame. (unit: 1us).

It will not be affected by he performance of PC, because FPGA handles the process in the LE-580FX. Tell you the exact timing of data received/transmitted.

Filter To Capture The Specific Packets

LE-580FX is not only able to capture all frames but also filter the specific packets. Filtering conditions can be set by MAC/IP address, protocols (ARP/IP/ICMP/IGMP/TCP/UDP/use defined), and specifying IP address/port/packet size etc.

LAN Analysis Software, Ethereal

Captured data can be used with LAN analysis software, Ethereal / Wireshark.
LE-580FX works as network adaptor. Able to control LE-580FX by using Ethereal / Wireshark.

PG mode generates test packets at your specified transmitting speed. Tell you the processing ability of the network devices and how they work at the high traffic. Test packets are generated in the FPGA, so it will not be affected by the performance of PC.

User Defined Test Packets

User can define 2-7 layer of data frames up to 128, and transmit them continuously or selected times. Add errors (CRC etc.) and VLAN/MPLS tags. Captured packets can be used as transmitting packets.

Hardware Counter For Statistic

Calculate statistic information in the FPGA to know the quality of network.

Display the results in trend charts and graphs for each port. LE-580FX does not only calculate numbers of data, but also calculate by each error, packet size, collision type and filtering.

Error Type:	TCP Checksum, IP Checksum, Alignment Error, Dribble Error, CRC Error, DI Checksum Error, Sequence Miss (Series Error), BERT Error
Packet Size:	Less than 64 byte. 64-127byte, 128-255byte, 256-511byte, 512-1023byte, 1024-1518byte, more than 1518byte.
Collision Type:	Total collisions, numbers of transmission by 1 collision, numbers of transmission by 2 collisions, numbers of transmission by failing 16 collisions, numbers of transmission by collision happened after 512bit time.

QoS Test (VLAN Supported)

Able to have the network Qos Test by transmitting test data from PortA(B) to PortB(A). Test packet lines can be set up to 8, includes VLAN VID (0-4095) and CoS (0-7) Parameter. QoS test tells you the packet loss and latency etc.
