Grouped according to their impact, the R&S SMW provides the following connector
types:
●
Chapter 12.2.2.1, "Global Connectors", on page 715
●
Chapter 12.2.2.2, "Baseband Local Connectors", on page 717
Grouped according to their impact on the baseband or on the RF signal, the same con-
nectors are divided into:
●
Chapter 12.2.3, "Trigger Marker Clock Settings", on page 720
●
Chapter 12.2.4, "RF Connectors Settings", on page 722
12.2.1 Required Options
●
The R&S SMW is always equipped with six USER interfaces.
Additional options are not required.
●
Option standard or wideband baseband generator (R&S SMW-B10/-B9) per signal
path.
Required for the support and configuration of the local T/M/C connectors, 6 with
R&S SMW-B10 and 4 with R&S SMW-B9.
12.2.2 About Local and Global Connectors
Signal to Connector Mapping
As described in Chapter 5.5.1, "Basics on Signals, Modulation Types and Filters Used
the Baseband Domain", on page 224, the R&S SMW uses several internally generated
and externally supplied signals. To handle these signals and more than two baseband
signals, the R&S SMW introduces the concept of signal to connector mapping. The
available signals are not dedicated to a particular connector but can be mapped to one
or more globally shared USER or local T/M/C connectors.
The signal mapping and the polarity, the trigger threshold, and the input impedance of
the input connectors are configurable parameters. The connectors settings are grou-
ped in the Global Connectors Settings and Local Connectors Settings dialogs.
For an overview of the required configuration steps, refer to "General Workflow"
on page 731.
12.2.2.1 Global Connectors
The R&S SMW is equipped with USER x interfaces which can be freely assigned a
selection of signals and which can be configured as both inputs and outputs.
A common threshold and input impedance is effective for all trigger and clock signal
inputs provided at the USER connectors. The settings influence the custom digital
modulations, the generation of waveforms or multicarrier signals, and all digital stand-
ards.
