Touching the topmost summary box in the status area of the Ports SetupPorts Setup screen
displays the status shown below.
This screen presents detailed information about the current physical status of
the received signal at the Ethernet interface.
The physical status information consists of the following parameters:
Bit rate, which shows the current bit rate.
Bit rate difference, which shows the difference in bit rate between received
signal and reference source signal.
Accumulated difference, which shows the accumulated bit rate difference
between the received signal and the reference source signal.
Link, which shows the link status of Ethernet.
Link partner abilities, which shows the abilities of the opposite interface port.
(Only available for Electrical)
Timestamp source availabilities, which shows the status of the external signals
used for timestamp.
Bit rateBit rate
The currently received bit rate is shown in bits per second (bps).
Bit rate differenceBit rate difference
The current difference between the received signal and the reference source
signal is shown in both parts per million (ppm) and bits per second (bps).
Accumulated Accumulated differencedifference
The accumulated difference between the received signal and the reference
source signal is shown. The information is presented as number of bits of
difference detected over the accumulation period.
This is important information for identifying small frequency differences, which may not
be visible by showing the current bit rate difference.
The accumulated difference information is accumulated continuously. The
accumulation is reset when measurement is started or restarted.
