WN504 Network Impairment Test Card

• Provides 2-port 1-link bidirectional emulation function.

• It has a wide range of impairment functions and can accurately

  emulate impairment at linear velocity stream.

• Delay transmission of all packets or specific packets can achieve

  Jitter Buffer.

• All messages or specific messages are discarded, duplicated,

  modified, reordered according to the set proportion.

• Messages with specific content can be inserted at a set rate, and

  ultra-long frames, ultra-short frames, and FCS error frames can

  be constructed and inserted.

• Background data traffic for specific content can be inserted at a

  set rate.

• Link bandwidth can be limited by a set ratio.

• BER Simulation can be generated at a set ratio.

  
  

Basic traffic testing

• 4 × 10/100/1000M RJ45 ports are available to generate wire-

  speed traffic.

• Can change the speed based on ports.

• Can set the source MAC address, destination MAC address, frame

  length, and payload content.

• Traffic can be counted based on ports.

• Statistics include the number of packets received, the number of

  packets sent, the receive rate, the transmit rate, and the FCS error

  packet.

Loopback and NIC functions

P3 and P4 ports can be used as physical layer/MAC layer loopback

P3 and P4 ports can be used as Gigabit network card interfaces

       The P3 and P4 ports of the WN504 have Ethernet loopback function, 

which can provide physical layer data loopback and MAC layer data 

loopback function, which can be used as an Ethernet loopback alone, 

or can be combined with the impairment and traffic of the test card to

achieve multi-scenario integration testing. At the same time, P3 and 

P4 ports can also be used as Gigabit network card adapter ports, thus

bringing more convenience to software and hardware system debugging.

Operating temperature

Operating humidity

A single test card supports one impairment link, and a single client can support up to three test cards to operate at the

same time
