The TOGGLE ON/OFF key switches the selected modulation (digital standard, digital
modulation or ARB) on or off.
BB In/Out block
The block is displayed only if the Digital Baseband Connectivity (option R&S SMBV-K18)
is installed.
As input, the "BB In/Out" block controls the baseband input module for external I/Q sig-
nals. Externally generated realtime baseband signals are fed into the digital signal path
via the digital interface. The signal is transferred directly to the I/Q modulator (I/Q Mod
function block).
Conversely, as output, the block is used to configure the digital I/Q output. The internally
generated baseband signal is configured in the Baseband function block.
The digital settings are performed in the corresponding menus. I and Q components can
also be swapped (I/Q Swap). The status line in a block displays the currently active con-
trol, e.g. "Output" denotes that the I/Q baseband signal is provided by the digital output.
The ON/OFF TOGGLE key switches the active function(s) of the block on or off.
AWGN/IMP A block
This block is displayed only if a baseband generator (R&S SMBV-B10/B50/B51) is instal-
led.
In this block (digital) I/Q impairments for the baseband path can be set. With the aid of
the software for AWGN generation (option R&S SMBV-K62), an (additive) noise signal
can be produced.
AWGN and impairments can be activated independently of each other in the appropriate
menus. The settings are displayed in the block. The entire block can be activated or
deactivated. If the block is deactivated, the signal passes through the block unchanged.
In addition, the differential I/Q output is configured in this block.
The TOGGLE ON/OFF key switches the active functions of the block on or off. The func-
tions (AWGN, impairments or both) are activated in the respective menus.
Graphics block
With this block, the baseband signal can be graphically displayed in real time. The block
is displayed only if a baseband generator is installed.
The TOGGLE ON/OFF key opens or closes the graphics window.
3.3 RF Section
An RF path is configured by installing a frequency option that comprises all required
modules.
One of the following options must be installed.
