1 Preface
The R&S SGU is an upconverter in the frequency range of 10 MHz to 40 GHz.
Optimized for use in automated test equipment (ATE), the instrument offers fast settling
times in an exceptionally small form factor and low power consumption. The R&S SGU
has LO connectors for coupling multiple generators to a common LO source and can
be equipped with a mechanical step attenuator.
1.1 Key Features
The key features of the R&S SGU include the following:
●Compact size and low power consumption
●Remote connection via PCI Express, minimizing the setup time
Alternatively, LAN or USB connections available
●Coherent LO input and output connectors, also usable as MIMO input/output and
phase coherent I/Q demodulation
●Linux operating system
●Graphical user interface R&S SGMA-GUI to set up and control one or more
R&S SGU instruments simultaneously from one remote computer, available for
Windows and Linux systems
1.2 Documentation Overview

2.1 Putting into Operation
This section describes the basic steps to be taken when setting up the R&S SGU for
the first time.
Risk of injury and instrument damage
The instrument must be used in an appropriate manner to prevent electric shock, fire,
personal injury, or damage.
●Do not open the instrument casing.
●Read and observe the "Basic Safety Instructions" delivered as a printed brochure
with the instrument.
In addition, read and observe the safety instructions in the following sections.
Notice that the data sheet may specify additional operating conditions.
Risk of instrument damage due to inappropriate operating conditions
Specific operating conditions are required to ensure accurate measurements and to
avoid damage to the instrument. Observe the information on appropriate operating
conditions provided in the basic safety instructions and the instrument's data sheet.
Instrument damage caused by electrostatic discharge
Electrostatic discharge (ESD) can damage the electronic components of the instrument
and the device under test (DUT). Electrostatic discharge is most likely to occur when
you connect or disconnect a DUT or test fixture to the instrument's test ports. To pre-
vent electrostatic discharge, use a wrist strap and cord and connect yourself to the
ground, or use a conductive floor mat and heel strap combination.

devices. Before switching on the instrument, observe the information on appropriate
operating conditions provided in the data sheet. In particular, ensure the following:
●All fan openings are unobstructed and the airflow perforations are unimpeded. A
minimum distance of 10 cm to other objects is recommended.
●The instrument is dry and shows no sign of condensation.
●The instrument is positioned as described in the following sections.
●The ambient temperature does not exceed the range specified in the data sheet.
●Signal levels at the input connectors are all within the specified ranges.
●Signal outputs are connected correctly and are not overloaded.
2.1.1 EMI Suppression
Electromagnetic interference (EMI) may affect the measurement results.
To suppress generated Electromagnetic Interference (EMI):
●Use suitable shielded cables of high quality. For example, use double-shielded RF
and LAN cables.
Note: USB cables are of varying and often poor quality. Therefore, check the qual-
ity of each individual USB cable as described in the service manual.
●Always terminate open cable ends.
●Note the EMC classification in the data sheet
2.1.2 Unpacking and Checking the Instrument
Unpack the R&S SGU carefully and check the contents of the package.
●Check if all items listed on the delivery note, including this getting started manual,
are included in the delivery.
●Check the R&S SGU for any damage.
If the contents are damaged, immediately contact the carrier who delivered the
package.
Packing material
Retain the original packing material. If the instrument needs to be transported or ship-
ped later, you can use the material to protect the control elements and connectors.

Risk of injury during transportation
The carrying handles at the front and side of the casing are designed to lift or carry the
instrument. Do not apply excessive force to the handles. If a handle is ripped off, the
falling instrument can cause injury.
2.1.3 Accessory List
The instrument comes with the following accessories:
●Power cable
●Getting started printed manual
2.1.4 Placing or Mounting the Instrument
The R&S SGU is designed for use under laboratory conditions, either on a bench top
or in a rack using a rack adapter kit (order number see data sheet).
Bench top operation
If the R&S SGU is operated on a bench top, the surface should be flat. The instrument
can be used in horizontal position, standing on its feet.

Risk of injury and instrument damage if stacking instruments
A stack of instruments may tilt over and cause injury. Furthermore, the instruments at
the bottom of the stack may be damaged due to the load imposed by the instruments
on top.
Observe the following instructions when stacking instruments:
●Never stack more than three instruments with the same dimensions (width and
length). If you need to stack more than three instruments, install them in a rack.
●The overall load imposed on the lowest instrument must not exceed 500 N.
●All instruments should have the same dimensions (width and length).
If you need to stack smaller instruments on the top, the overall load imposed on the
lowest instrument must not exceed 250 N.
●If the instruments have foldable feet, fold them in completely.
Rack mounting
The R&S SGU can be installed in a rack using a rack adapter kit (Order No. see data
sheet). The installation instructions are part of the adapter kit.
Risk of instrument damage due to insufficient airflow in a rack
If you mount several instruments in a rack, you need an efficient ventilation concept to
ensure that the instruments do not overheat. Insufficient airflow for a longer period can
disturb the operation and even cause damage.
2.1.5 Switching the Instrument On and Off
The R&S SGU is automatically adapted to the AC voltage supplied. There is no need
to set the voltage manually or change fuses. The [AC supply and power switch] is at
the rear of the unit.

To connect the AC supply
► Connect the R&S SGU to the AC power source using the AC power cable deliv-
ered with the instrument.
Note: The instrument is in compliance with safety class EN61010-1.
Connect the instrument only to a socket with earthing contact.
To start up the instrument
1. Connect the instrument to the AC supply.
2. To turn on the power, press the main power switch to position I (On).
To switch between standby and ready state
► Press the [POWER ON /STAND BY] key briefly to switch the instrument from the
standby to ready state or vice versa.
In ready state, the button is green. The instrument is ready for operation. All mod-
ules are power-supplied and the R&S SGU initiates its startup procedure.
In standby state, the button is orange. The standby power mode keeps the power
switch circuits and the remote control system active.
Start-up and booting
The instrument boots the operating system and starts the instrument firmware. During
the booting process, the green [POWER ON /STAND BY] key blinks. If the previous
session was terminated regularly, the instrument uses the last setup with the relevant
instrument settings.
Once the startup procedure has been terminated, the instrument is ready for operation.
In the R&S SGMA-GUI, select "Instrument > Preset" function to return the instrument
to its defined reset/preset state, if the current setup is no longer relevant.
To customize the start settings, use the "SGMA-GUI > File > Save As/Open" function.
To shut down the instrument
To shut down the R&S SGU, proceed as described below.
