Event Log: Logs up to 1000 event entries. If there are more than 1000 events,
l
Circular keeps the latest entries. The oldest entry will be deleted so that the new event can be
added.
l
Blocked stops recording new events after 1000 entries. The latest entries will not be logged.
l
TX Start: Separated or Coupled. Configures how the measurements are started when in BERT and
Multiple Streams test modes.
l
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.
l
Coupled: Transmitter and receiver are turned on at the same time, and the Tx and Rx meas-
urements start at the same time at the start of the test.
l
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 measurement.
When a device is selected the following fields can be seen on the screen:
l l
External Clock Input: 1pps (SMA Port). The SMA Port must be used for the 1pps signal.
l
UTC ToD: Displays the Coordinated Universal Time (UTC) Time of Day once it is acquired.
l
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.
Both test sets must be configured to the same Clock Sync Time.
Clock Synchronization is not supported on all the test set models.
Check with customer care for availability.
l
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
