5 Trying out the instrument
This chapter introduces the most important functions and settings of the
R&S
SMM100A step by step. The complete description of the functionality and its
usage is given in the R&S SMM100A user manual. Basic instrument operation is
described in Chapter 7, "Instrument control" , on page 75.
Prerequisites
●
The instrument is set up, connected to the power supply, and started up as
described in
Chapter 3, "Preparing for use" , on page 15.
For the first signal generation tasks, you use the internal baseband and reference
signal, so you do not need any additional signal source. More complex signal
generation tasks, however, require an instrument equipped with additional options
and/or external signals. Each task description lists its prerequisites.
The screenshots in this description show a fully equipped instrument. Con-
sider that, the block diagram displayed on your particular instrument can dif-
fer from the one used in the example.
The instrument is manually operated via the touchscreen. Try out the following:

● Saving and recalling settings .......................................................................... 61
● Generating an EUTRA/LTE signal ...................................................................64
5.1 Generating an unmodulated carrier
We start out by generating a simple unmodulated signal. The R&S SMM100A in
this example can be a base unit in its minimal configuration (i.e. with installed
R&S
SMM-B1006).
