Logical signals, streams and channels at the interfaces
This section provides background information and introduction to the topics. The
description is divided in parts that follow the logical decision process when configuring
the instrument. It supports the manual configuration for simple test scenarios.
The settings provided in the "System Configuration" dialog guide you throughout this
decision process automatically. For complex routing scenarios, like MIMO configura-
tion and especially configuration involving several instruments, we recommend that
you use the "System Configuration" functionality as a start and central configuration
point.
For an overview of the interfaces and their characteristics, refer to:
●
Chapter 3.3.2, "Overview of the Baseband Signal Sources", on page 132
●
Chapter 3.3.3, "Overview of the Baseband and RF Output Signals", on page 133

3.3.1 Physical Location of the Input and Output Interfaces
This section focuses on the input and output interfaces of the instrument. For a
detailed overview of all front and rear panel connectors, see Chapter 2.2, "Instrument
Tour", on page 52.
Naming conventions for the input and output interfaces and Show Connector
function
The R&S SMW is a highly modular instrument that can be equipped with different com-
binations of hardware and software options. To increase the serviceability of the instru-
ment, the design of the different hardware board is similar. However, this similarity
together with the customizable connectors direction and user definable signals can
cause cabling and configuration faults. To simplify the cabling and to minimize this
error source, it is important to identify the interfaces in any possible hardware and sys-
tem configuration.
The instrument provides the following two methods for identifying the connectors:
●
A connector naming rule that follows the predefined structure
<Board Name> <Number> <Direction>, e.g. CODER 2 IN, BBMM 2 OUT, etc.
●
A built-in Show Connector function, that indicates the selected connector on the
rear panel of the instrument with a blinking LED.
The short and long connector names (e.g. COD 2 IN and CODER 2 IN or "Coder 2 IN")
are used interchangeably.
●
The Figure 3-1 shows the digital interfaces on the rear panel together with the
associated GUI term (highlighted in orange color).
The figure shows a standard baseband instrument, equipped with R&S SMW-B10
and R&S SMW-B13T.
The wideband baseband does not support digital interfaces.
