The measurement and event log settings are configured in this screen.

 

• Mode: Manual, timed, or auto mode are available.

  • Manual mode: Starts and stops the measurements manually.

  • Timed mode: Defines the duration of the test; after the test is started, the test will run for the configured duration and stop automatically.

 

 

• TX Start: Separated or Coupled. Configures how the measurements are started when in BERT and Multiple Streams test modes.

  • Separated: Independent control (Start/Stop) of the transmitter is enabled. At the start of the test only the receiver is turned on -- the user must start the transmitter manually.

  • Coupled: Transmitter and receiver are turned on at the same time, and the Tx and Rxmeasurements start at the same time at the start of the test.

 

• Clock (ToD) Synchronization Device: Disable, GPS, 1PPS, Local, Atomic 1PPS. Select the device to be used to synchronize the clock to perform the One Way Delay.

  When a device is selected the following fields can be seen on the screen:measurement.

 

• External Clock Input: 1pps (SMA Port). The SMA Port must be used for the 1pps signal.

• UTC ToD: Displays the Coordinated Universal Time (UTC) Time of Day once it is acquired.

• Clock Sync Time: Time field to configure the UTC ToD that both test sets, carrying out a one-way delay test between each other, will be synchronizing their internal time stamping at.

Clock Synchronization is not supported on all the test set models. Check with customer care for availability.

 

• Gratuitous ARP: ON or OFF. If set to ON, a gratuitous ARP is performed. When the test port has an IP connection, an ARP request will be transmitted at regular intervals to keep the router/gateway ARP table aware of the test set's IP address. This setting is useful for long-term L3 routed testing.

• Results Auto Save: ON or OFF. If set to ON, results will be saved automatically.

• Maximum Number of Saved Events: 128/256/512/1024
