Generating an EUTRA/LTE signal
The main application field of the R&S
SMM100A is the generation of digital signals in
accordance with several telecommunication and wireless standards, like WCDMA,
EUTRA/LTE or WLAN, to name a few. This example uses the digital standard
EUTRA/LTE to introduce the way you can access and interact with the instrument and
experience the advantages provided by the additional options.
The minimum requirement for R&S
SMM100A in this example is a base unit equipped
with:
●
Option baseband generator R&S
SMM-B9
●
Option EUTRA/LTE R&S
SMM-K55
●
Option frequency R&S
SMM-B1006
To generate a downlink test signal
The main focus of the following example is not on the R&S
SMM100A 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 digital 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
SMM100A 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 func-
tions and dialogs, like the "Filter" settings. The "Trigger In", "Marker" and "Clock"
tabs comprise the settings related to the corresponding function.
