1.6 Transmission Features
Transmission Load Configuration
When the test mode is Traffic Test, QoS Test, or BERT, you can set the transmission load by setting
the Tx rate and the Tx mode.
When the mode is Traffic Test or BERT, you can define a single frame. In QoS test mode, you can
define up to eight frames and assign them to the various transmission channels.
Tx Rate Settings
Traffic Format
When Manual has been selected in the Test menu, you can select a traffic format.
Constant
When the traffic format is Constant, frames are sent continuously at a constant interval. You can
change the interframe gap (IFG) by changing the Tx rate.

Burst
When the traffic format is Burst, frames are transmitted in bursts: frame transmission starts and
stops repeatedly at a specified interval. You can change the interframe gap (IFG) by changing the
Tx rate. You can specify the number of Tx frames in the burst interval by setting Burst Number, and
you can specify the interval of repetition by setting Interval.
