The R&S SMW provides all settings required to configure the output connectors, to
establish the connections to the connected RF instruments and to control them. The
settings are grouped in the "System configuration" > External RF and I/Q dialog. In this
dialog, you find an overview of all available I/Q input and output connectors and config-
ure the connection to the external instruments.
Once the connection is established, the R&S SMW acts as a master instrument and
controls the setup-related parameters of any connected further processing external
instrument. Among others, this apples to connected R&S SGT, R&S SGS (also in com-
bination with R&S SGU), R&S SZU, R&S FSW.
9.4.1 Prerequisites for Control of External Instruments from the
R&S SMW
Required are the following connections between the R&S SMW and the external instru-
ments:
●
Physical remote control connection over LAN or USB
The remote control connection to the external instruments must be in status con-
nected, see "Remote Connection Status" on page 152.
●
Physical signal connection for the digital or analog I/Q signal
●
For the most test setups, the instruments must use a common reference fre-
quency signal.
Suitable reference frequency signal sources are:
– An external common reference source
– The distributed reference frequency of the R&S SMW.
9.4.2 Test Setups
The test setup depends on the external instrument and the used I/Q output signal (digi-
tal, analog single-ended or analog differential).
See for example Figure 3-17, Figure 3-19, Figure 3-21 and Figure 3-28.
See also Chapter 3.1.2, "From a Test Scenario to the Required System Configuration",
on page 124.
9.4.3 Control of Connected R&S SGT
Up to 6 R&S SGT instruments can be connected to the R&S SMW. As with all external
instruments, you find R&S SGT related information like the connection status and the
used RF level and frequency values in the External RF and I/Q dialog. This dialog pro-
vides also additional short information on each of the connected instruments.
Settings related to the output signal are grouped in the I/Q Digital dialog.
