Note:
When a word consists of more than 1 byte, the graph indicates these bytes and
separates them with a hyphen.
The first word contains control information while the following words carry the AxCs, that
means the I/Q data.
R&S
DigIConf shows the signals in different colors, as well as the related AxCs. Active
signals are strongly colored, while the inactive signals are shown in pale colors. If the
signals in the graph overlap, the active signals are always in the foreground. Below the
graph, a legend explains the signals and their assigned colors.
Available Data Rate (I/Q)
Displays the available data rate of the I/Q data, calculated with the formula:

Assigned Data Rate (AxC)
Displays the assigned I/Q data rate of all active signals. This parameter depends on the

I/Q Data Interleaving
Activates I/Q data interleaving.
The following graphs show the sample arrangement and transmission order for uplink
and downlink:
