1.3 Test Modes
Traffic Test Mode
In this mode, you generate traffic and measure the network throughput by defining a single Tx frame
and specifying the frame length and Tx rate.
When the other device is in Loopback Test mode, you can perform latency measurement.
Loopback Test Mode
In this mode, the source and target addresses of received frames are reversed, and the frames are
sent back to their source. The AQ1300/AQ1301 takes statistics of the received frames.
Testing is performed with the other device set to Traffic Test, QoS Test, or BERT mode.
QoS Test Mode
In this mode, you can generate QoS measurement traffic and measure the network QoS performance
by defining a Tx frame with up to eight channels of QoS parameters and specifying the frame length
and Tx rate. The AQ1300/AQ1301 takes statistics of each individual QoS channel.
When the device under test is in Loopback Test mode, you can perform latency measurement on
individual QoS channels.
PING Test Mode
In this mode, you can verify layer 3 connectivity. You can ping a single host at intervals of 1 s or less (1
ms minimum).
You can also use traceroute testing to check the route to the target (the other device).
BERT Mode
In this mode, bit error rate testing is performed. The AQ1300/AQ1301 inserts a pseudo-random pattern
(PN15) into the payload of the Tx frame and checks whether or not bit errors are occurring between
itself and the other device.
The other device must be set to BERT mode or Loopback Test mode.
