You may also use the following rules and the subsequent sections to determine the sup-
ported signal paths:
●
One frontend provides three RF connectors at the front panel: either RF 1 COM + RF
1 OUT + RF 2 COM or RF 3 COM + RF 3 OUT + RF 4 COM.
●
One TX or RX module can be connected to one frontend only.
●
Basic frontend:
A basic RF frontend (R&S CMW-B590A) provides a connection to one TX module
and one RX module. It connects either RF 1/2 to TX/RX 1 or RF 3/4 to TX/RX 2.
●
Advanced frontend:
An advanced RF frontend (R&S CMW-B590D) provides a connection to up to two TX
and RX modules. If two advanced frontends are installed, one half of the installed TX/
RX modules is connected to the first frontend, the other half to the second frontend.
If two TX and RX modules are connected to one advanced frontend, the following
rules apply:
–
Both TX modules can be connected to the same RF connector (sum signal). This
allows e.g. to provide two cell signals at one connector.
It is also possible to connect the two TX modules to different RF connectors of
the same frontend. Exception: It is not possible to connect TX 1 to RF 2 and at
the same time TX 2 to RF 1.
–
Both RX modules can be connected to the same RF connector (split signal). This
allows e.g. to measure the same signal with two applications in parallel.
It is also possible to connect the two RX modules to different RF connectors of
the same frontend. Exception: It is not possible to connect RX 1 to RF 2 and at
the same time RX 2 to RF 1.
–
The two previous rules can be combined. It is for example possible to connect
both TX modules and both RX modules to the same RF COM connector.
●
Fixed and flexible baseband link
–
A fixed link (R&S CMW-S550A) provides connections between TX/RX 1 and
baseband boards used for firmware application instance 1. It supports also con-
nections between TX/RX 2 and baseband boards used for firmware application
instance 2.
Thus firmware application instance 1 can only use TX/RX 1 and instance 2 can
only use TX/RX 2.
–
A flexible link (R&S CMW-S550B/M) allows connections between all TX/RX mod-
ules and all baseband boards/signaling units.
Thus all firmware application instances can use all TX/RX modules.
●
One baseband module, signaling unit, TX module or RX module can be used by only
one firmware application at a time.
●
The number of instances available for a certain firmware application depends on the
installed hardware and the active software licenses:
–
If no software license is available for a firmware application, the application is not
visible at all.
–
If at least one software license is available for the application, the number of
visible/configurable instances depends on the number of installed hardware units
on which the application can be executed. Depending on the type of the appli-
cation these hardware units are baseband generator boards, baseband mea-
surement boards or signaling units.
