Power Blazer 627
Summary - Time Error / Wander
Max Abs TE (ns) the maximum absolute packet selected time error
value collected since the beginning of the test. The pass/fail verdict is
also displayed when enabled.
Pk-pk pkt sel TE (ns) indicates the peak-to-peak packet selected time
error value collected since the beginning of the test (the difference
between Min pkt sel TE and Max pkt sel TE values).
Note: The following metrics are collected without any filtering.
Pkt sel cTE (ns) indicates the packet selected constant time error
which is an average value of time error over the defined period as
follows (refer to Pkt cTE Averaging Period on page 447):
since the beginning of the test when the Pkt cTE Averaging Period
is set to Elapse Time.
for the averaging period defined when the Pkt cTE Averaging
Period is set to a value other than the Elapse Time. The first value
is only available after the initial average period has elapsed (in
addition to the sample selection window of 200 seconds), the
value is then updated every x second based on the selected
Window Step Size.
Max pkt sel cTE (ns) indicates the maximum packet selected constant
time error value collected since the beginning of the test. The pass/fail
verdict is also displayed when enabled.
For Time Error measurement with either G.8275.1 or G.8275.2 profile:
PDV indicates the difference between the delay of a packet (difference
between timestamp at receiving end and the original timestamp at the
transmitter) and the minimum packet delay value for the specified
interval. PDV (ns) and PDV Max (ns) values are reported for both
Forward (BC -> Client) and Reverse (Client -> BC) directions.
