Max. Useful Data Rate
Requires "Source > External/TS Player".
Displays the maximum data rate, that is derived from the current modulation parameter
settings.
The value is the optimal value at the TS input interface, that is necessary for the modu-
lator.
If "Stuffing > On", the value indicates the maximum useful data rate, that is allowed in
the transport stream.
If "Stuffing > Off", the value indicates the transport stream input data rate that is
required for the transport stream.
How to: Chapter 5.3, "Calculating the Input Data Rate" , on page 52.

Measured Data Rate
Requires "Source > External".
Displays the measured value of the data rate r
meas
of one of the following:
●
External transport stream including null packets input at "User 1" connector
●
External transport stream including null packets input at "IP Data/LAN" connector
(TSoverIP)
The value r
meas
equals the sum of useful data rate r
useful
and the rate of null packets r
0
:
If "Stuffing > Off", ensure that the measured data rate equals the maximum useful data
rate (r
meas
= r
max. useful
).

Useful Data Rate
Requires "Source > External/TS Player".
Displays the data rate of useful data r
useful
of the external transport stream. The data
rate is measured at the input of the installed input interface.
