Basic Safety Instructions

Operating states and operating positions

The product may be operated only under the operating conditions and in the positions specified by the
manufacturer, without the product's ventilation being obstructed. If the manufacturer's specifications are
not observed, this can result in electric shock, fire and/or serious personal injury or death. Applicable local
or national safety regulations and rules for the prevention of accidents must be observed in all work
performed.

1. Unless otherwise specified, the following requirements apply to Rohde & Schwarz products:
predefined operating position is always with the housing floor facing down, IP protection 2X, use only
indoors, max. operating altitude 2000 m above sea level, max. transport altitude 4500 m above sea
level. A tolerance of ±10 % shall apply to the nominal voltage and ±5 % to the nominal frequency,
overvoltage category 2, pollution degree 2.

2. Do not place the product on surfaces, vehicles, cabinets or tables that for reasons of weight or stability
are unsuitable for this purpose. Always follow the manufacturer's installation instructions when
installing the product and fastening it to objects or structures (e.g. walls and shelves). An installation
that is not carried out as described in the product documentation could result in personal injury or
even death.

3. Do not place the product on heat-generating devices such as radiators or fan heaters. The ambient
temperature must not exceed the maximum temperature specified in the product documentation or in
the data sheet. Product overheating can cause electric shock, fire and/or serious personal injury or
even death.

Electrical safety

If the information on electrical safety is not observed either at all or to the extent necessary, electric shock,
fire and/or serious personal injury or death may occur.

1. Prior to switching on the product, always ensure that the nominal voltage setting on the product
matches the nominal voltage of the mains-supply network. If a different voltage is to be set, the power
fuse of the product may have to be changed accordingly.

2. In the case of products of safety class I with movable power cord and connector, operation is
permitted only on sockets with a protective conductor contact and protective conductor.

3. Intentionally breaking the protective conductor either in the feed line or in the product itself is not
permitted. Doing so can result in the danger of an electric shock from the product. If extension cords
or connector strips are implemented, they must be checked on a regular basis to ensure that they are
safe to use.

4. If there is no power switch for disconnecting the product from the mains, or if the power switch is not
suitable for this purpose, use the plug of the connecting cable to disconnect the product from the
mains. In such cases, always ensure that the power plug is easily reachable and accessible at all
times. For example, if the power plug is the disconnecting device, the length of the connecting cable
must not exceed 3 m. Functional or electronic switches are not suitable for providing disconnection
from the AC supply network. If products without power switches are integrated into racks or systems,
the disconnecting device must be provided at the system level.

5. Never use the product if the power cable is damaged. Check the power cables on a regular basis to
ensure that they are in proper operating condition. By taking appropriate safety measures and
carefully laying the power cable, ensure that the cable cannot be damaged and that no one can be
hurt by, for example, tripping over the cable or suffering an electric shock.

1171.0000.42 - 09 Page 3

Basic Safety Instructions

6. The product may be operated only from TN/TT supply networks fuse-protected with max. 16 A (higher
fuse only after consulting with the Rohde & Schwarz group of companies).

7. Do not insert the plug into sockets that are dusty or dirty. Insert the plug firmly and all the way into the
socket provided for this purpose. Otherwise, sparks that result in fire and/or injuries may occur.

8. Do not overload any sockets, extension cords or connector strips; doing so can cause fire or electric
shocks.

9. For measurements in circuits with voltages V

> 30 V, suitable measures (e.g. appropriate

rms

measuring equipment, fuse protection, current limiting, electrical separation, insulation) should be
taken to avoid any hazards.

10. Ensure that the connections with information technology equipment, e.g. PCs or other industrial
computers, comply with the IEC 60950-1 / EN 60950-1 or IEC 61010-1 / EN 61010-1 standards that
apply in each case.

11. Unless expressly permitted, never remove the cover or any part of the housing while the product is in
operation. Doing so will expose circuits and components and can lead to injuries, fire or damage to the
product.

12. If a product is to be permanently installed, the connection between the protective conductor terminal
on site and the product's protective conductor must be made first before any other connection is
made. The product may be installed and connected only by a licensed electrician.

13. For permanently installed equipment without built-in fuses, circuit breakers or similar protective
devices, the supply circuit must be fuse-protected in such a way that anyone who has access to the
product, as well as the product itself, is adequately protected from injury or damage.

14. Use suitable overvoltage protection to ensure that no overvoltage (such as that caused by a bolt of
lightning) can reach the product. Otherwise, the person operating the product will be exposed to the
danger of an electric shock.

15. Any object that is not designed to be placed in the openings of the housing must not be used for this
purpose. Doing so can cause short circuits inside the product and/or electric shocks, fire or injuries.

16. Unless specified otherwise, products are not liquid-proof (see also section "Operating states and
operating positions", item 1). Therefore, the equipment must be protected against penetration by
liquids. If the necessary precautions are not taken, the user may suffer electric shock or the product
itself may be damaged, which can also lead to personal injury.

17. Never use the product under conditions in which condensation has formed or can form in or on the
product, e.g. if the product has been moved from a cold to a warm environment. Penetration by water
increases the risk of electric shock.

18. Prior to cleaning the product, disconnect it completely from the power supply (e.g. AC supply network
or battery). Use a soft, non-linting cloth to clean the product. Never use chemical cleaning agents such
as alcohol, acetone or diluents for cellulose lacquers.

Operation

1. Operating the products requires special training and intense concentration. Make sure that persons
who use the products are physically, mentally and emotionally fit enough to do so; otherwise, injuries
or material damage may occur. It is the responsibility of the employer/operator to select suitable
personnel for operating the products.

1171.0000.42 - 09 Page 4

Basic Safety Instructions

2. Before you move or transport the product, read and observe the section titled "Transport".

3. As with all industrially manufactured goods, the use of substances that induce an allergic reaction
(allergens) such as nickel cannot be generally excluded. If you develop an allergic reaction (such as a
skin rash, frequent sneezing, red eyes or respiratory difficulties) when using a Rohde & Schwarz
product, consult a physician immediately to determine the cause and to prevent health problems or
stress.

4. Before you start processing the product mechanically and/or thermally, or before you take it apart, be
sure to read and pay special attention to the section titled "Waste disposal/Environmental protection",
item 1.

5. Depending on the function, certain products such as RF radio equipment can produce an elevated
level of electromagnetic radiation. Considering that unborn babies require increased protection,
pregnant women must be protected by appropriate measures. Persons with pacemakers may also be
exposed to risks from electromagnetic radiation. The employer/operator must evaluate workplaces
where there is a special risk of exposure to radiation and, if necessary, take measures to avert the
potential danger.

6. Should a fire occur, the product may release hazardous substances (gases, fluids, etc.) that can
cause health problems. Therefore, suitable measures must be taken, e.g. protective masks and
protective clothing must be worn.

7. Laser products are given warning labels that are standardized according to their laser class. Lasers
can cause biological harm due to the properties of their radiation and due to their extremely
concentrated electromagnetic power. If a laser product (e.g. a CD/DVD drive) is integrated into a
Rohde & Schwarz product, absolutely no other settings or functions may be used as described in the
product documentation. The objective is to prevent personal injury (e.g. due to laser beams).

8. EMC classes (in line with EN 55011/CISPR 11, and analogously with EN 55022/CISPR 22,
EN 55032/CISPR 32)
 Class A equipment:

Equipment suitable for use in all environments except residential environments and environments
that are directly connected to a low-voltage supply network that supplies residential buildings
Note: Class A equipment is intended for use in an industrial environment. This equipment may
cause radio disturbances in residential environments, due to possible conducted as well as
radiated disturbances. In this case, the operator may be required to take appropriate measures to
eliminate these disturbances.

 Class B equipment:

Equipment suitable for use in residential environments and environments that are directly
connected to a low-voltage supply network that supplies residential buildings

Repair and service

1. The product may be opened only by authorized, specially trained personnel. Before any work is

2 Welcome to the R&S EX-IQ-BOX...

Welcome to the R&S EX-IQ-BOX...

...the Digital Interface Module

While in the past the transmission of the analog I/Q signals had played an important role,
nowadays it is the digital I/Q signals that are significant. The utilization of digital I/Q signals
leads to the employment of different transmission protocols and still involves the devel­opment of different interface types with a great variety of physical characteristics.

The R&S EX-IQ-BOX, as a configurable interface module, is designed to solve this prob-
lem. The main application field of this device is the conversion of signal properties and
transmission protocols of the R&S instruments into User Defined or standardized signal
formats and vice versa.

To digitally transmit I/Q signals, R&S instruments like signal generators, signal analyzers,
communication testers and the R&S EX-IQ-BOX communicate with each other, using an
R&S wide standardized transmission protocol, which is based on LVDS (Low Voltage
Differential Signaling).

For applications with User Defined protocols the R&S EX-IQ-BOX enables either serial
or parallel transmission of I/Q signals to a DUT, including variable clock modes, various
data rates as well as different logical signal levels.

In applications with standardized protocols the R&S EX-IQ-BOX not only provides the
I/Q data, but also the control information of the respective standard. Equipped with the
respective options, the R&S EX-IQ-BOX supports the standardized protocol CPRI
(Common Packet Radio Interface). This protocol defines a combined interface for the
transmission of I/Q and control data between the baseband and RF module of a base
station.

The R&S EX-IQ-BOX is directly connected to the digital interface of an R&S instrument
by using an LVDS cable. For connection to the DUT, various interchangeable adapters
are available, so called breakout boards. Breakout boards adapt the signals physically.
A breakout board is directly connected to the user interface on the front panel of the
R&S EX-IQ-BOX.

For User Defined applications, two different breakout boards are provided with the

●

R&S EX-IQ-BOX, supporting single ended and differential signals.

For CPRI applications, separate options support the respective signal formats.

●

The R&S EX-IQ-BOX is controlled via the USB interface. It is operated from a PC by
using the configuration software R&S DigIConf.

Test setups of the R&S EX-IQ-BOX 1409.5505.02 with instruments of the R&S SMU or
R&S FSQ families provide control of the R&S EX-IQ-BOX without using the digital inter­face configuration software R&S DigIConf. But this constellation applies only to User
Defined applications.

Due to the enhanced capabilities of the R&S EX-IQ-BOX 1409.5505K04, this model is
exclusively controlled by R&S DigIConf and applies to all applications.

11User Manual 1409.5570.32 ─ 05

R&S®EX-IQ-BOX

Welcome to the R&S EX-IQ-BOX...

● In User Defined mode R&S DigIConf controls the protocol settings, data format and
multiple clock scenarios as internal or device clocking (external) for data transmis­sion.

● For standardized protocols R&S DigIConf provides all settings of the respective
standard. Additionally, control functions according to the standard are supported from
the R&S EX-IQ-BOX and are set with the aid of R&S DigIConf.

In addition, the R&S DigIConf can be remote controlled, from a PC either directly or via
a network.

Equipped with the respective options, the R&S EX-IQ-BOX has integrated a Waveform
Output Memory (64 Msamples) as well as a Multi Waveform Playback to generate test
signals which were created externally, e.g. by means of R&S WinIQSIM2 or Matlab sim­ulation software. R&S DigIConf takes the generated data from the control PC, checks the
data and loads it into the R&S EX-IQ-BOX. The Multi Waveform Playback provides
simultaneous playback of up to four signals.

Also, for operating in receiver mode a Recording Memory (512 MB) option is available.
The signal data can be recorded over a period of time and then saved in a file.

Waveform Memory, Recording Memory and Multi Waveform Playback can be performed
only with R&S DigIConf and standardized protocols.

Software options for Digital Standards with R&S®WinIQSIM2TM are also available. For
example, GSM / EDGE, 3GPP FDD, EUTRA / LTE, etc., i.e. all those supported by CPRI.

The Digital Standards are described in individual manuals available on the
Rohde & Schwarz internet site or on the user documentation CD-ROM of R&S®WinIQ­SIM2TM.

The signals that are generated with the aid of the R&S WinIQSIM2 software can be output
by the Waveform Memory or the Multi Waveform Playback of the R&S EX-IQ-BOX. Sig­nals calculated by Matlab software can be directly loaded.

For detailed information on all available options refer to chapter 3.2.2, "Options",
on page 22".

3 System Overview

System Overview

Basic Operating Modes

This section comprises an overview of the instruments communicating with the R&S EX­IQ-BOX and some basic operating modes. It also describes available hardware and soft­ware components for operating the R&S EX-IQ-BOX.

The R&S EX-IQ-BOX provides transmission of I/Q data between R&S instruments and
external devices (DUTs). In applications with standardized protocols, the R&S EX-IQ­BOX operates bidirectional. Data can be sent and received at the same time. In the User
Defined mode only one data direction is possible at the same time.

In the following configurations, signal transmission is shown by means of an R&S instru­ment operating as transmitter to the DUT via the R&S EX-IQ-BOX. Vice versa, the
R&S EX-IQ-BOX works as a receiver, while it receives a test signal from a DUT and
transfers it to an R&S instrument for analyzing. For further configuration examples refer
to chapter 5, "Application Examples", on page 47.

An overview of instruments working with the R&S EX-IQ-BOX is given in chapter 3.2.5,

"R&S Instruments Working with the R&S EX-IQ-BOX", on page 25. For the available

options and their respective part numbers refer to chapter 3.2.2, "Options",

with an R&S signal generator. The R&S EX-IQ-BOX operates in transmitter mode from
the signal generator to the DUT.

3.1.3 Remote Control of the R&S EX-IQ-BOX

Remote control functionality provides access to the measurement from a remote com­puter (external controller). By means of remote commands, settings or data are trans­mitted to the R&S EX-IQ-BOX via R&S DigIConf. Remote programs automate repeated
settings. The remote control programs can either run on the same computer as the
R&S DigIConf or on any PC in the network.

Remote control of R&S DigIConf is performed via a LAN socket communication protocol,
also referred to as Raw Socket communication.

Socket communication uses the TCP/IP network protocol. A VISA installation on remote
controller side is not mandatory. Connection can also be performed with a Win Socket
communication.

If you use a VISA library, the access is more convenient.

4.4 Installing R&S DigIConf

This section describes how to install the software R&S DigIConf (Digital Interface
Configurator), the tool for controlling the protocol settings of the R&S EX-IQ-BOX. It also

encloses the hardware and software requirements which have to be met for installation.

Software and Hardware Requirements

It is recommended that your PC fulfills the following minimum requirements:

Component Minimum requirement

Operating system Windows 2000 SP4 / XP SP1 (32 bit), Windows 7

CPU Pentium 4, 1 GHz or higher

RAM 256 MB

Hard disk 100 MByte free space

Monitor XGA monitor (1024 x 768)

Interfaces USB 2.0

Tip: USB 1.1 is also supported, but due to the lower transmission speed, it is
recommended to operate with USB 2.0.

For some Rohde & Schwarz instruments, e.g. the R&S CMW500, it is possible to install
R&S DigIConf directly on the instrument. The operating manual of the instrument states
if the instrument supports this mode of operation. The installation on the instrument is the
same as on the PC, see below.

Getting Started

Installing R&S DigIConf

Prerequisites

● Uninstall the old software version, as described in chapter 4.4.3, "Uninstalling",

on page 38.

Close any running applications.

●

● Disconnect all R&S EX-IQ-BOXes and do not connect any during installation.

4.4.1 Installation

The setup file DigIConf_x.xx.xxx.exe for the installation of the R&S DigIConf is included
in the delivery of your R&S EX-IQ-BOX or can be downloaded from the R&S website:

http://www.rohde-schwarz.com/product/EX-IQ-Box.html

► Execute DigIConf_x.xx.xxx.exe

in the windows explorer and follow the installation instructions of the R&S DigIConf
setup wizard.
The version number x.xx.xxx in the filename represents the current version. Each
update has a new release number.

During installation the program creates various subdirectories needed by the application.

Additionally, the installation wizard checks the status of the registry entry "DisableCAD"
in order to exclude logon conflicts during later operation. The wizard prompts you to
modify the DisableCAD status accordingly, in order to fix these conflicts.

Fig. 4-4: R&S

"Yes"

●

DigIConf Installation > Modify DisableCAD

Accept modification.
The installation wizard sets DisableCAD=0 in the registry.

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
\policies\system]"DisableCAD"=dword:00000000

A connected R&S EX-IQ-BOX does not cause any conflicts at startup and logon.

"No"

●

Reject modification.
The parameter DisableCAD remains 1 and you must disconnect the R&S EX-IQ­BOX before every login and connect it afterwards again.

Backgound: Depending on this registry entry, a connected R&S EX-IQ-BOX may cause
an infinite loop at the Windows logon prompt. It occurs during a logon because Windows
interprets the internal SmartCard of the R&S EX-IQ-BOX as a medium for login. You find
more details also in chapter 4.4.4, "Known Restrictions on SmartCard Related Issues",
on page 39.

R&S®EX-IQ-BOX

Getting Started

Installing R&S DigIConf

Fig. 4-9: R&S DigIConf Installation > Logon message

Windows interprets the internal SmartCard of the R&S EX-IQ-BOX as a medium for login
and therefore causes this message.

When trying to confirm, the system reacts in different ways, depending on the status of
the "DisableCAD" registry entry:

1. "Logon Message" remains

The system repeats the SmartCard error message and blocks the login. Disable­CAD=1, i.e. the Windows security attention sequence (CTR-ALT-Del) for login is
skipped. Windows tries to log in with the smart card and fails.
To terminate:

a)

Disconnect the R&S EX-IQ-BOX to enable login.
b) Log in.
c)

Connect the R&S EX-IQ-BOX again.

Note: To solve this conflict for later operation, deactivate DisableCAD in the registry.
The DisableCAD parameter determines whether you need to press CTRL+ALT
+DEL keys to log in, or whether the login window directly appears after at startup or
after locked desktop.

2. "Logon Message" disappears
The system forwards to the "Computer Locked" dialog box. In this case, Disable­CAD=0, Windows requires users to press CTR-ALT-Del (security attention
sequence) for login.

a) Press CTRL+ALT+DEL to unlock the computer and log in as usual.

The connection to the R&S EX-IQ-BOX may remain.

4.4.4.1 How to avoid the SmartCard Conflict

The only way to avoid the conflict reliably, is to set DisableCAD=0. If the setting has not
been modified yet, proceed as follows.

To modify this registry entry, R&S DigIConf provides the file DisableCAD.reg in the
directory:

%APPDATA%\Rohde-Schwarz\DigIConf\Registry

► Execute DisableCAD.reg to deactivate the setting, i.e. to enable the "Press Ctrl-

Alt-Del" security attention sequence.
The entry is automatically set to 0. Login can now be performed with connected
R&S EX-IQ-BOXes without conflicts.

Application Examples

CPRI Test Setup

The test setup covers the downlink and the uplink. It provides testing both directions either
simultaneously, i.e. full duplex, or uplink and downlink seperately.

The downlink signal flow

The R&S baseband signal generator feeds a baseband signal (e.g. an LTE downlink) in
the R&S specific I/Q format to the R&S EX-IQ-BOX. The R&S EX-IQ-BOX converts the
R&S I/Q format into the CPRI protocol. The CPRI link transmits the I/Q baseband signal
and control & management information from the R&S EX-IQ-BOX to the DUT, in this case
the CPRI RE Device.

The CPRI RE device extracts the baseband signal from the CPRI link and executes an
I/Q modulation to a certain carrier frequency RF. The resulting RF signal is sent to the
R&S spectrum-analyzer, to perform various measurements, e.g. ACP (Adjacent Channel

Power) or EVM (Error Vector Magnitude) evaluation.

The uplink signal flow

The R&S vector signal generator feeds an RF signal (e.g. an LTE uplink) via the antenna
input into the CPRI RE device. The DUT converts the signal from RF to baseband and
transmits the baseband signal by using the CPRI link.

The R&S EX-IQ-BOX extracts the I/Q baseband signal from the CPRI protocol and sends
the signal in the R&S specific I/Q format to the R&S signal analyzer for demodulation.

All settings regarding the baseband signal (e.g. LTE) are directly controlled by the R&S
signal generator and analyzer, respectively.

CPRI settings like I/Q mapping or link settings are controlled by the configurator software
R&S DigIConf .

In addition to the I/Q data, C&M (Control and Management) information is embedded in
the CPRI protocol. These parameters are also set with the aid of R&S DigIConf.

An Ethernet connector provides fast C&M, and the R&S DigIConf inline text console can
be used for slow C&M.

5.2.2 Typical CPRI REC Test Setup

Example of a typical CPRI REC (Radio Equipment Control = baseband unit) test scenario,
where the R&S EX-IQ-BOX acts as a RF module RE (Remote Equipment).

The test setup requires the CPRI breakout board, option R&S EXBOX-B85, the CPRI
REC Test, option R&S EXBOX-K11 and the configuration software R&S DigIConf. For
details on available options, see chapter 3.2.2.1, "Standardized Protocols", on page 22.

The test setup covers the downlink and the uplink. It provides testing both directions either
simultaneously, i.e. full duplex, or uplink and downlink separately.

The downlink signal flow

The DUT, in this case the CPRI REC device, generates a digital baseband signal (e.g.
an LTE downlink) and transmits this signal over the CPRI link.

The R&S EX-IQ-BOX extracts the I/Q baseband signal from the CPRI protocol and sends
the signal in the R&S specific I/Q format to the R&S signal analyzer for demodulation.

The R&S signal analyzer features various measuring methods, as e.g. ACP (Adjacent
Channel Power) or EVM (Error Vector Magnitude) evaluation. Use this measurement
methods to examine the validity and quality of the digital baseband signal, or to evaluate
the influence of numerical imperfections, e.g. quantization effects depending on the I/Q
resolution.

The uplink signal flow

The R&S signal generator feeds an UE uplink signal (e.g. an LTE uplink) in the R&S
specific I/Q format to the R&S EX-IQ-BOX.

The R&S EX-IQ-BOX converts the R&S I/Q format into the CPRI protocol. The CPRI link
transmits the I/Q baseband signal and control & management information from the
R&S EX-IQ-BOX to the DUT, in this case the CPRI REC device.

The DUT must now be able to demodulate the UE uplink signal. Use the various func­tionalities of the R&S signal generator, e.g. add Channel Fading, AWGN (Additive White
Gaussian Noise) and I/Q impairments in order to perform a very powerful and realistic
receiver / demodulator measurement with this test scenario.
