Network Compensation
Displays the compensating delay.
If the delay is added to the network path delay, the overall delay is constant and of
known value. The value of the compensating delay is set by examining incoming time-
stamps compared to a local time standard. The value of the compensating delay is
adjusted so that the frame carrying the timestamp is delivered at the correct time.

Tx Processing Delay
Displays the minimum signal turnaround time through the transmitter.
A minimum delay implies "Tx Compensation Delay = 0
µ
s". The minimum delay is
determined by the signal processing in the COFDM and depends on the DAB mode.
"Tx Processing Delay" = "Tx Delay" - "Tx Compensation Delay"
