To generate a downlink test signal
The main focus of the following example is not on the R&S
SMW capabilities and
the features provided by the firmware option. The example aims rather to help
you get familiar with the settings and configuration principle common for the digi-
tal standards.
We use one of the provided EUTRA test models (E-TM) to show how to generate
a test signal upon a quick selection.
1. On the R&S
SMW front panel, press the [PRESET] key to start out in a
defined instrument configuration.
2. In the block diagram, select "Baseband > Beyond 3G Standards > EUTRA/
LTE".
The EUTRA/LTE dialog appears and displays the general settings provided for
the digital standard.
As in the user interfaces of all digital standards, the "EUTRA/LTE" dialog is
divided into several tabs. The "General" tab comprises the primary settings of
the standard, the functions for storing and recalling settings and provides
access to further functions and dialogs, like the "Filter" settings. The "Trigger
In", "Marker" and "Clock" tabs comprise the settings related to the correspond-
ing function.
The more complex the digital standard itself is, the more comprehensive the
further dialog and tab structure. The start dialog of each digital standard, how-
ever, follows a repeating dialog structure that comprises the tabs "General",
"Trigger In", "Marker" and "Clock". (See also
