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

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.

1171.0000.52 - 08 Page 4

Basic Safety Instructions

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.

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

1171.0000.52 - 08 Page 5

Basic Safety Instructions

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.

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

Basic Safety Instructions

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)

R&S FPS is started, the operating system boots and the instrument firmware is
started automatically.

To ensure that the instrument software functions properly, certain rules must be
adhered to concerning the operating system.

Risk of causing instrument unusability

The instrument is equipped with the Windows 7 operating system. Addi­tional software can therefore be installed on the instrument. The use and
installation of additional software may impair instrument function. Thus, run
only programs that Rohde & Schwarz has tested for compatibility with the
instrument software.

The drivers and programs used on the instrument under Windows 7 have
been adapted to the instrument. Existing instrument software must always
be modified using only update software released by Rohde & Schwarz.

Windows Operating System

The following program packages have been tested:

●

Symantec Endpoint Security – Virus-protection software

●

FileShredder - for reliable deletion of files on the hard disk

Error message display

Note that any error messages caused by the Windows 7 operating system
are only visible on an external monitor or via Remote Desktop from a con­troller PC. Thus, if operation of the R&S FPS seems to fail for no obvious
reason, try connecting a monitor or a controller PC to check for any mes­sages awaiting confirmation or action.

(See Chapter 2.3, "Connecting USB Devices", on page 22 or Chapter 5.6,

"How to Set Up Remote Desktop", on page 69)

Preparing for Use

2.2.1 Virus Protection

Take appropriate steps to protect your instruments from infection. Use strong fire­wall settings and scan any removable storage device used with a Rohde &
Schwarz instrument regularly. It is also recommended that you install anti-virus
software on the instrument. Rohde & Schwarz does NOT recommend running
anti-virus software in the background ("on- access" mode) on Windows-based
instruments, due to potentially degrading instrument performance. However, it
does recommend running it during non-critical hours.

For details and recommendations, see the Rohde & Schwarz White Paper

1DC01: Malware Protection.

2.2.2 Service Packs and Updates

Microsoft regularly creates security updates and other patches to protect Win­dows-based operating systems. These are released through the Microsoft Update
website and associated update server. Instruments using Windows, especially
those that connect to a network, should be updated regularly.

For details and recommendations, see the Rohde & Schwarz White Paper

1DC01: Malware Protection.

Preparing for Use

Windows Operating System

2.2.3 Login

Windows 7 requires that users identify themselves by entering a user name and
password in a login window. By default, the R&S FPS provides two user
accounts:

●

"Instrument": an administrator account with unrestricted access to the com­puter/domain

●

"NormalUser": a standard user account with limited access

Secure User Mode

If the secure user mode option (R&S FPS-K33) is installed, an additional
account is provided: the "SecureUser".

The "SecureUser" is a standard user account with limited functionality. In
particular, administrative tasks such as LAN configuration or general instru­ment settings are not available. Furthermore, for a "SecureUser", data that
the R&S FPS normally stores on the solid-state drive is redirected to volatile
memory instead. Users can access data that is stored in volatile memory
during the current instrument session. However, when the instrument’s
power is removed, all data in volatile memory is erased.

For details, see Chapter 2.6, "Protecting Data Using the Secure User

Mode", on page 25.

Automatic login

For the administrator account, an automatic login function is active by default. If
activated, login is carried out automatically for the administrator (with full access)
in the background when the R&S FPS is started, without having to enter a pass­word. This function is active until you explicitly deactivate it or change the pass­word.

For information on how to deactivate or re-activate the automatic login, refer to

Chapter 2.2.3.1, "The Automatic Login Function", on page 19.

Passwords

For all default user accounts, the initial password is 894129. Note that this pass­word is very weak, and it is recommended that you change the password for both
users after initial login. You can change the password in Windows 7 for any user
at any time via "Start > Control Panel > User Accounts".

Changing the password and use of auto-login function

Note that when you change the default passwords, the default auto-login
function no longer works! You must re-activate it manually as described in

"Re-activating the automatic login function" on page 20.

Be aware if the auto-login function is deactivated and the R&S FPS is
rebooted: since the R&S FPS has no real display, you require an external
monitor and keyboard or a Remote Desktop access to the R&S FPS to
enter the password. Otherwise, the Windows operating system does not
complete login and the R&S FPS remains inoperable.

2.2.3.1 The Automatic Login Function

When shipped, the instrument is already configured to automatically log on to
Windows 7 using the default administrator account ("Instrument") and password.

To change the settings for the automatic login function for the R&S FPS, a
controller PC or an external monitor and keyboard must be connected to
the R&S FPS. See Chapter 5.6, "How to Set Up Remote Desktop",
on page 69.

If the auto-login function is deactivated and the R&S FPS is rebooted, you
require an external monitor and keyboard or a Remote Desktop access on
the R&S FPS to enter the password. Otherwise, the Windows operating
system does not complete login and the R&S FPS remains inoperable.

Deactivating the automatic login function

To deactivate the automatic login function, perform the following steps:

1.

Select the "Windows" icon in the toolbar to access the operating system of the
R&S FPS (see also Chapter 2.2.4, "Accessing the Start Menu", on page 21).

4. Press the ENTER key to confirm.

The automatic login function is deactivated. The next time you switch on the
instrument, you are prompted to enter your user name and password before
the firmware is started. (You must use an external monitor and keyboard or
Remote Desktop from a controller PC, not the R&S FPS miniature display!)

Adapting the automatic login function to a new password

If you change the "Instrument" user's (administrator's) password, which is used
during automatic login, this function no longer works. You must adapt the settings
for the command that activates the auto login function first.

If the SecureUser or the NormalUser are enabled, those passwords are used for
autologin. In that case, if you change any of the passwords, the autologin function
must be adapted each time you change the user account.

1. Open the C:\R_S\INSTR\USER\NO_AUTOLOGIN.REG file in any text editor

(e.g. Notepad).

Preparing for Use

2. In the line "DefaultPassword"="894129", replace the default password

(894129) by the new password which is to be used for automatic login.

Connecting USB Devices

2.3 Connecting USB Devices

The USB interfaces of the R&S FPS allow you to connect USB devices directly to
the instrument. This number can be increased as necessary by using USB hubs.
Due to the large number of available USB devices, there is almost no limit to the
expansions that are possible with the R&S FPS.

The following list shows various USB devices that can be useful:

●

Memory stick for easy transfer of data to/from a computer (e.g. firmware
updates)

●

CD-ROM drives for easy installation of firmware applications

●

Keyboard or mouse to simplify the entry of data, comments, file names, etc.

●

Printer for printing measurement results

Installing USB devices is easy under Windows, because all USB devices are
plug&play. After a device is connected to the USB interface, the operating system
automatically searches for a suitable device driver.

If Windows does not find a suitable driver, it prompts you to specify a directory
that contains the driver software. If the driver software is on a CD, connect a USB
CD-ROM drive to the instrument before proceeding.

When a USB device is then disconnected from the R&S FPS, Windows immedi­ately detects the change in hardware configuration and deactivates the corre­sponding driver.

All USB devices can be connected to or disconnected from the instrument during
operation.

Connecting a memory stick or CD-ROM drive

If installation of a memory stick or CD-ROM drive is successful, Windows informs
you that the device is ready to use. The device is made available as a new drive
and is displayed in Windows Explorer. The name of the drive depends on the
manufacturer.

Connecting a keyboard

The keyboard is detected automatically when it is connected. The default input
language is English – US.

2.6 Protecting Data Using the Secure User Mode

During normal operation, the R&S FPS uses a solid-state drive to store its operat­ing system, instrument firmware, instrument self-alignment data, and any user

25Getting Started 1319.3362.02 ─ 07

R&S®FPS

Protecting Data Using the Secure User Mode

data created during operation. If necessary, the solid-state drive can be removed
from the R&S FPS and locked in a secure place to protect any classified data it
may contain.

Redirecting storage to volatile memory

Alternatively, to avoid storing any sensitive data on the R&S FPS permanently,
the secure user mode was introduced (option R&S FPS-K33). In secure user
mode the instrument’s solid-state drive is write-protected so that no information
can be written to memory permanently. Data that the R&S FPS normally stores
on the solid-state drive is redirected to volatile memory instead, which remains
available only until the instrument is switched off. This data includes:

●

Windows 7 operating system files

●

Firmware shutdown files containing information on last instrument state

●

Self-alignment data

Preparing for Use

●

General instrument settings such as the IP address

●

Measurement settings

●

User data created during operation

●

Any data created by other applications installed on the R&S FPS, for example
text editors (Notepad), the Clipboard, drawing tools, etc.

Users can access data that is stored in volatile memory just as in normal opera­tion. However, when the instrument’s power is switched off, all data in this mem­ory is cleared. Thus, in secure user mode, the instrument always starts in a
defined, fixed state when switched on.

To store data such as measurement results permanently, it must be stored to an
external storage device, such as a memory stick.

Limited storage space

The volatile memory used to store data in secure user mode is restricted to
256 MB. Thus, a "Memory full" error can occur although the hard disk indi­cates that storage space is still available.

Storing required data permanently

Any data that is to be available for subsequent sessions with the R&S FPS must
be stored on the instrument permanently, before activating the secure user mode.

26Getting Started 1319.3362.02 ─ 07

R&S®FPS

Protecting Data Using the Secure User Mode

This includes predefined instrument settings, transducer factors and self-align­ment data.

Self-alignment data

Note that self-alignment data becomes invalid with time and due to temper­ature changes. Therefore, to achieve optimal accuracy, it may be preferable
to perform a new self-alignment at the start of each new session on the
R&S FPS.

Restricted operation

Since permanent storage is not possible, the following functions are not available
in secure user mode:

●

Firmware update

●

Activating a new option key

Preparing for Use

Furthermore, since the "SecureUser" used in secure user mode does not have
administrator rights, administrative tasks such as LAN configuration and some
general instrument settings are not available. Refer to the description of the basic
instrument setup (SETUP menu) to find out which functions are affected.

Remote Desktop restricted for "SecureUser" by default

For security reasons, the "SecureUser" is not allowed Remote Desktop
access to the R&S FPS by default. You must explicitly add the "Secure­User" to the Remote Desktop group (see Chapter 5.6.5, "How to Add or

Remove Users to the Remote Desktop Users Group", on page 77). If you

do not allow this user Remote Desktop access, the "SecureUser" can only
operate the R&S FPS using remote commands or via the miniature display.

Activating and deactivating secure user mode

Only a user with administrator rights can activate (and deactivate) the secure user
mode. Once activated, a restart is required. The special user "SecureUser" is
then logged on to the R&S FPS automatically (using the automatic login function,
see Chapter 2.2.3.1, "The Automatic Login Function", on page 19). While the
secure user mode is active, a message is displayed in the status bar at the bot­tom of the screen, and in the miniature display "SecUsr" is displayed.

To deactivate the secure user mode, the "SecureUser" must log off and the
"Instrument" user (administrator) must log on.

Additional Hardware Options Without External Connectors

3.3.1 OCXO Option (R&S FPS-B4)

This option generates a 10 MHz reference signal with a very precise frequency. If
installed, and if no external signal is used, this signal is used as an internal refer­ence.

Warm-up time for OCXO

When the instrument is switched on, the OCXO requires an extended
warm-up time (see data sheet). No warm-up time is required when starting
from standby mode.

3.3.2 Bandwidth Extension 160 MHz (R&S FPS-B160)

The signal analysis bandwidth of the R&S FPS can be extended by a hardware
option (R&S FPS-B160). The bandwidth extension allows for a linear bandwidth
up to a maximum of 160 MHz with an output sample rate of up to 10 GHz. While
the extension can be activated or deactivated manually in the R&S FPS base unit
(I/Q Analyzer application), it is activated automatically in some applications that
also support I/Q data analysis. See the application-specific documentation for
details.

Functions and Settings in the Mini Display Menu

4 Miniature Display

The R&S FPS is equipped with a miniature display on the front panel (see also

"Mini display" on page 30).

The display provides the following information:

●

The serial number, firmware version and model of the instrument

●

The IP address of the instrument

●

The GPIB address of the instrument

●

System messages, for example when errors occur

Furthermore, it provides the following functions directly on the instrument:

●

Configuring network settings, including LXI and GPIB parameters

●

Performing selftests, self alignment

●

Resetting the instrument to a predefined state

●

Changing display settings

The miniature front panel display is meant as a service interface, not for
measurement display. If the display fails for any reason, switch the instru­ment off and back on again to restore the display.

Note that any error messages caused by the Windows 7 operating system
are not displayed on the miniature front panel display. They are only visible
on an external monitor or via RemoteDesktop from a controller PC. Thus, if
operation of the R&S FPS seems to fail for no obvious reason, try connect­ing a monitor or a controller PC to check for any messages awaiting confir­mation or action.

Controlling the R&S FPS Remotely

5 Controlling the R&S FPS Remotely

Since the R&S FPS was designed without a screen (except for the mini display
for basic information and settings), it will typically be used to perform measure­ments under remote control. However, the developers of such programs will find it
convenient to get familiar with the instrument and its functions using manual oper­ation initially, and then design the programs accordingly. Once developed and
tested, the programs can be executed from a remote PC, with no manual interac­tion required. The computer that is used for remote control is called "controller"
here.

All instrument functions and settings, as well as any background informa­tion, are described for manual operation, assuming an external keyboard,
mouse and monitor are connected, or a controller PC with Remote Desktop
is being used.

Various methods for remote control are supported:

●

Connecting the instrument to a (LAN) network (see Chapter 5.2, "How to Con-

figure a Network", on page 58)

●

Using the LXI browser interface in a LAN network (see Chapter 5.2.3, "How to

Configure the LAN Using the LXI Web Browser Interface", on page 61)

●

Using the Windows Remote Desktop application in a LAN network (see Chap-

ter 5.6, "How to Set Up Remote Desktop", on page 69)

Remote operation

Remote operation of the instrument from a connected computer is possible using
SCPI commands. Sending remote commands requires the instrument to be con­figured in a LAN network or connected to a PC via the GPIB interface as descri­bed in Chapter 5.2, "How to Configure a Network", on page 58 and Chapter 5.5,

"How to Start a Remote Control Session from a PC", on page 69.

Manual operation via Remote Desktop

Remote Desktop is a Windows application which can be used to access and con­trol the instrument from a remote computer through a LAN connection. While the
R&S FPS is in operation, the instrument's graphical results and control elements
are displayed on the remote computer, and Remote Desktop provides access to
all of the applications, files, and network resources of the instrument. Thus,

47Getting Started 1319.3362.02 ─ 07

remote (manual) operation of the instrument is possible. The following tasks can
be performed using Remote Desktop:

●

Access to the control functions via a virtual front panel

●

Printout of measurement results directly from the controller

●

Storage of measured data on the controller's hard disk

This documentation provides basic instructions on setting up the Remote Desktop

Within this interface description, the term GPIB is used as a synonym for
the IEC/IEEE bus interface.

5.1.1 LAN Interface

To be integrated in a LAN, the instrument is equipped with a LAN interface, con­sisting of a connector, a network interface card and protocols. The network card
can be operated with the following interfaces:

●

10 Mbit/s Ethernet IEEE 802.3

●

100 Mbit/s Ethernet IEEE 802.3u

●

1Gbit/s Ethernet IEEE 802.3ab

For remote control via a network, the PC and the instrument must be connected
via the LAN interface to a common network with TCP/IP network protocol. They
are connected using a commercial RJ45 cable (shielded or unshielded twisted
pair category 5). The TCP/IP network protocol and the associated network ser­vices are preconfigured on the instrument. Software for instrument control and the
VISA program library must be installed on the controller.

VISA library

Instrument access is usually achieved from high level programming platforms
using VISA as an intermediate abstraction layer. VISA encapsulates the low level
VXI, GPIB, LAN or USB function calls and thus makes the transport interface
transparent for the user. See Chapter 5.1.4, "VISA Libraries", on page 57 for
details.

49Getting Started 1319.3362.02 ─ 07

R&S®FPS

The R&S FPS supports various LAN protocols such as LXI, RSIB, raw socket or
the newer HiSLIP protocol.

IP address

Only the IP address or a valid DNS host name is required to set up the connec­tion. The host address is part of the "VISA resource string" used by the programs
to identify and control the instrument.

The VISA resource string has the form:

TCPIP::host address[::LAN device name][::INSTR]

or

TCPIP::host address::port::SOCKET

where:

Controlling the R&S FPS Remotely

Remote Control Interfaces and Protocols

●

TCPIP designates the network protocol used

●

host address is the IP address or host name of the device

●

LAN device name defines the protocol and the instance number of a sub­instrument;

– inst0 selects the VXI-11 protocol (default)
– hislip0 selects the newer HiSLIP protocol

●

INSTR indicates the instrument resource class (optional)

●

port determines the used port number

●

SOCKET indicates the raw network socket resource class

Example:

●

Instrument has the IP address 192.1.2.3; the valid resource string using
VXI-11 protocol is:

TCPIP::192.1.2.3::INSTR

●

A raw socket connection can be established using:

TCPIP::192.1.2.3::5025::SOCKET

Identifying instruments in a network

If several instruments are connected to the network, each instrument has its
own IP address and associated resource string. The controller identifies
these instruments by means of the resource string.

● Socket Communication................................................................................... 52

● LXI Web Browser Interface............................................................................. 52

5.1.1.1 VXI-11 Protocol

The VXI-11 standard is based on the ONC RPC (Open Network Computing
Remote Procedure Call) protocol which in turn relies on TCP/IP as the network/
transport layer. The TCP/IP network protocol and the associated network services
are preconfigured. TCP/IP ensures connection-oriented communication, where
the order of the exchanged messages is adhered to and interrupted links are
identified. With this protocol, messages cannot be lost.

5.1.1.2 HiSLIP Protocol

The HiSLIP (High Speed LAN Instrument Protocol) is the successor protocol for
VXI-11 for TCP-based instruments specified by the IVI foundation. The protocol
uses two TCP sockets for a single connection - one for fast data transfer, the
other for non-sequential control commands (e.g. Device Clear or SRQ).

HiSLIP has the following characteristics:

●

High performance as with raw socket network connections

●

Compatible IEEE 488.2 support for Message Exchange Protocol, Device
Clear, Serial Poll, Remote/Local, Trigger, and Service Request

●

Uses a single IANA registered port (4880), which simplifies the configuration
of firewalls

●

Supports simultaneous access of multiple users by providing versatile locking
mechanisms

●

Usable for IPv6 or IPv4 networks

51Getting Started 1319.3362.02 ─ 07

R&S®FPS

Controlling the R&S FPS Remotely

Remote Control Interfaces and Protocols

Using VXI-11, each operation is blocked until a VXI-11 device handshake
returns. However, using HiSLIP, data is sent to the device using the "fire
and forget" method with immediate return. Thus, a successful return of a
VISA operation such as viWrite() does not guarantee that the instru­ment has finished or started the requested command, but is delivered to the
TCP/IP buffers.

For more information see also the application note: 1MA208: Fast Remote Instru-

ment Control with HiSLIP.

5.1.1.3 Socket Communication

An alternative way for remote control of the software is to establish a simple net­work communication using sockets. The socket communication, also referred to
as "Raw Ethernet communication", does not necessarily require a VISA installa­tion on the remote controller side. It is available by default on all operating sys­tems.

The simplest way to establish socket communication is to use the built-in telnet
program. The telnet program is part of every operating system and supports a
communication with the software on a command-by-command basis. For more
convenience and to enable automation by means of programs, user-defined sock­ets can be programmed.

Socket connections are established on a specially defined port. The socket
address is a combination of the IP address or the host name of the instrument
and the number of the port configured for remote-control. All R&S FPS use port
number 5025 for this purpose. The port is configured for communication on a
command-to-command basis and for remote control from a program.

5.1.1.4 LXI Web Browser Interface

LAN eXtensions for Instrumentation (LXI) is an instrumentation platform for mea­suring instruments and test systems that is based on standard Ethernet technol­ogy. LXI is intended to be the LAN-based successor to GPIB, combining the
advantages of Ethernet with the simplicity and familiarity of GPIB. The LXI
browser interface allows for easy configuration of the LAN and remote control of
the R&S FPS without additional installation requirements.

52Getting Started 1319.3362.02 ─ 07

R&S®FPS

The instrument's LXI web browser interface works correctly with all W3C compli­ant browsers.

Via the LXI browser interface to the R&S FPS you can control the instrument
remotely from another PC. Manual instrument controls are available via the front
panel simulation. File upload and download between the instrument and the
remote PC is also available. Using this feature, several users can access and
operate the R&S FPS simultaneously. This is useful for troubleshooting or training
purposes.

For details, see Chapter 5.2.3, "How to Configure the LAN Using the LXI Web

Browser Interface", on page 61 and Chapter 5.7, "How to Control the R&S FPS
via the Web Browser Interface", on page 80.

If you do not want other users in the LAN to be able to access and operate
the R&S FPS you can deactivate this function.

Restrictions

Only user accounts with administrator rights can use the LXI functionality.
For details, see Chapter 2.2.3, "Login", on page 18.

To configure the LAN interface using the LXI web browser Interface, a con­troller PC or an external monitor, mouse and keyboard must be connected
to the R&S FPS. The settings required to set up this function are available
directly on the R&S FPS, via the mini display.

If no external monitor is connected to the R&S FPS, an additional driver is
required on the control PC in order to control the R&S FPS via its web
browser interface. If the driver is not available, the browser shows only a
black screen.

Download the TightVNC DFMirage driver from the official TightVNC web­site (http://www.tightvnc.com/download.php) and install it as described on
the website.

The current R&S FPS firmware was tested with the TightVNC DFMirage

5.1.2 GPIB Interface (IEC 625/IEEE 418 Bus Interface)

A GPIB interface is integrated on the rear panel of the instrument.

By connecting a PC to the R&S FPS via the GPIB connection you can send
remote commands to control and operate the instrument.

To be able to control the instrument via the GPIB bus, the instrument and the
controller must be linked by a GPIB bus cable. A GPIB bus card, the card drivers
and the program libraries for the programming language used must be provided
in the controller. The controller must address the instrument with the GPIB bus
address (see Chapter 5.2.4, "How to Change the GPIB Instrument Address",
on page 64). You can set the GPIB address and the ID response string. The

55Getting Started 1319.3362.02 ─ 07

R&S®FPS

Controlling the R&S FPS Remotely

Remote Control Interfaces and Protocols

GPIB language is set as SCPI by default and cannot be changed for the
R&S FPS.

Notes and Conditions

In connection with the GPIB interface, note the following:

●

Up to 15 instruments can be connected

●

The total cable length is restricted to a maximum of 15 m or 2 m times the
number of devices, whichever is less; the cable length between two instru­ments should not exceed 2 m.

●

A wired "OR"-connection is used if several instruments are connected in par­allel.

●

Any connected IEC-bus cables should be terminated by an instrument or con­troller.

5.1.3 USB Interface

For remote control via the USB connection, the PC and the instrument must be
connected via the USB type B interface. A USB connection requires the VISA
library to be installed. VISA detects and configures the R&S instrument automati­cally when the USB connection is established. You do not have to enter an
address string or install a separate driver.

USB address

The used USB address string is:

USB::<vendor ID>::<product ID>::<serial number>[::INSTR]

where:

●

<vendor ID> is the vendor ID for Rohde & Schwarz (0x0AAD)

●

<product ID> is the product ID for the Rohde & Schwarz instrument

●

<serial number> is the individual serial number on the rear of the instrument

5.1.4 VISA Libraries

VISA is a standardized software interface library providing input and output func­tions to communicate with instruments. The I/O channel (LAN or TCP/IP, USB, ...)
is selected at initialization time by one of the following:

●

The channel–specific address string ("VISA resource string") indicated in

Table 5-1

●

An appropriately defined VISA alias (short name).

A VISA installation is a prerequisite for remote control using the following interfa­ces:

How to Configure a Network

5.2 How to Configure a Network

Risk of network failure

Before connecting the instrument to the network or configuring the network,
consult your network administrator. Errors may affect the entire network.

The R&S FPS is equipped with a network interface and can be connected to an
Ethernet LAN (local area network). Provided the appropriate rights have been
assigned by the network administrator and the Windows 7 firewall configuration is
adapted accordingly, the interface can be used, for example:

●

To transfer data between a controller and the tester, e.g. in order to run a
remote control program; see the "Remote Control" chapter in the R&S FPS
User Manual

●

To access or control the measurement from a remote computer using the
"Remote Desktop" application (or a similar tool); see Chapter 5.6, "How to Set

Up Remote Desktop", on page 69

●

To connect external network devices (e.g. printers)

●

To transfer data from a remote computer and back, e.g. using network folders

A precondition for operating or monitoring the R&S FPS remotely is that it is con­nected to a LAN network or a PC connected to the GPIB interface. This is descri­bed here.

Windows Firewall Settings

A firewall protects an instrument by preventing unauthorized users from
gaining access to it through a network. Rohde & Schwarz highly recom­mends the use of the firewall on your instrument. R&S instruments are ship­ped with the Windows firewall enabled and preconfigured in such a way that
all ports and connections for remote control are enabled. For more details
on firewall configuration see the Rohde & Schwarz White Paper 1DC01:

Malware Protection and the Windows 7 help system.

Controlling the R&S FPS Remotely

How to Configure a Network

5.2.1 How to Connect the Instrument to the Network

There are two methods to establish a LAN connection to the instrument:

●

A non-dedicated network (Ethernet) connection from the instrument to an
existing network made with an ordinary RJ-45 network cable. The instrument
is assigned an IP address and can coexist with a computer and with other
hosts on the same network.

●

A dedicated network connection (Point-to-point connection) between the
instrument and a single computer made with a (crossover) RJ-45 network
cable. The computer must be equipped with a network adapter and is directly
connected to the instrument. The use of hubs, switches, or gateways is not
required, however, data transfer is still performed using the TCP/IP protocol.
An IP address has to be assigned to the instrument and the computer, see

Chapter 5.2.2, "How to Assign the IP Address", on page 59.

Note: As the R&S FPS uses a 1 GBit LAN, a crossover cable is not necessary
(due to Auto-MDI(X) functionality).

► To establish a non-dedicated network connection, connect a commercial

RJ-45 cable to one of the LAN ports.
To establish a dedicated connection, connect a (crossover) RJ-45 cable
between the instrument and a single PC.

If the instrument is connected to the LAN, Windows 7 automatically detects the
network connection and activates the required drivers.

The network card can be operated with a 1 GBit Ethernet IEEE 802.3u interface.

5.2.2 How to Assign the IP Address

Depending on the network capacities, the TCP/IP address information for the
instrument can be obtained in different ways.

●

If the network supports dynamic TCP/IP configuration using the Dynamic Host
Configuration Protocol (DHCP), all address information can be assigned auto­matically.

●

If the network does not support DHCP, or if the instrument is set to use alter­nate TCP/IP configuration, the addresses must be set manually.

By default, the instrument is configured to use dynamic TCP/IP configuration and
obtain all address information automatically. This means that it is safe to establish
a physical connection to the LAN without any previous instrument configuration.

59Getting Started 1319.3362.02 ─ 07

R&S®FPS

Risk of network errors

Connection errors can affect the entire network. If your network does not
support DHCP, or if you choose to disable dynamic TCP/IP configuration,
you must assign valid address information before connecting the instrument
to the LAN. Contact your network administrator to obtain a valid IP address.

Assigning the IP address directly on the R&S FPS

1. In the R&S FPS's mini display, navigate to "Network" > "DHCP".

2. If DHCP is "Off", you must enter the IP address manually, as described in the
following steps.
Note: When DHCP is changed from "On" to "Off", the previously set IP
address and subnet mask are retrieved.
If DHCP is "On", the IP address of the DHCP server is obtained automatically.
The configuration is saved, and you are prompted to restart the instrument.
You can skip the remaining steps.
Note: When a DHCP server is used, a new IP address may be assigned each
time the instrument is restarted. This address must first be determined on the
instrument itself. Thus, when using a DHCP server, it is recommended that
you use the permanent computer name, which determines the address via the
DNS server.

5.2.3 How to Configure the LAN Using the LXI Web Browser

Interface

The instrument's LXI browser interface works correctly with all W3C compliant
browsers.

If no external monitor is connected to the R&S FPS, an additional driver is
required on the control PC in order to control the R&S FPS via its web
browser interface. If the driver is not available, the browser shows only a
black screen.

Download the TightVNC DFMirage driver from the official TightVNC web­site (http://www.tightvnc.com/download.php) and install it as described on
the website.

The current R&S FPS firmware was tested with the TightVNC DFMirage
driver version 2.0.301.

► In the web browser, open the http://<instrument-hostname> or

http://<instrument-ip-address> page, e.g. http://10.113.10.203.
The default password to change LAN configurations is LxiWebIfc.

The "Instrument Home Page" (welcome page) opens.

●

"Help > Glossary" opens a document with a glossary of terms related to the
LXI standard.

5.2.3.1 LAN Configuration

The LAN configuration consists of three parts:

●

"IP configuration" provides all mandatory LAN parameters.

●

"Advanced LAN Configuration" provides LAN settings that are not declared
mandatory by the LXI standard.

●

"Ping Client" provides the ping utility to verify the connection between the
instrument and other devices.

IP Configuration

The "LAN Configuration > IP configuration" web page displays all mandatory LAN
parameters and allows their modification.

The "TCP/IP Mode" configuration field controls how the IP address for the instru­ment gets assigned (see also Chapter 5.2.2, "How to Assign the IP Address",
on page 59).

For the manual configuration mode, the static IP address, subnet mask, and
default gateway are used to configure the LAN. The automatic configuration
mode uses DHCP server or Dynamic Link Local Addressing (Automatic IP) to
obtain the instrument IP address.

Changing the LAN configuration is password-protected. The default pass­word is LxiWebIfc (notice upper and lower case characters).

Advanced LAN Configuration

The "LAN Configuration > Advanced LAN Configuration" parameters are used as
follows:

●

The "Negotiation" configuration field provides different Ethernet speed and
duplex mode settings. In general, the "Auto Detect" mode is sufficient.

●

"ICMP Ping" must be enabled to use the ping utility.

●

"VXI-11" is the protocol that is used to detect the instrument in the LAN.
According to the standard, LXI devices must use VXI-11 to provide a detection
mechanism; other additional detection mechanisms are permitted.

mDNS and DNS-SD are two additional protocols: Multicast DNS and DNS
Service Discovery. They are used for device communication in zero configura­tion networks working without DNS and DHCP

Ping Client

Ping is a utility that verifies the connection between the LXI-compliant instrument
and another device. The ping command uses the ICMP echo request and echo
reply packets to determine whether the LAN connection is functional. Ping is use­ful for diagnosing IP network or router failures. The ping utility is not password­protected.

To initiate a ping between the LXI-compliant instrument and a second connected
device:

1. Enable "ICMP Ping" on the "Advanced LAN Configuration" page (enabled
after an LCI).

2. Enter the IP address of the second device without the ping command and
without any further parameters into the "Destination Address" field (e.g.

10.113.10.203).

3. Select "Submit".

5.2.4 How to Change the GPIB Instrument Address

In order to operate the instrument via remote control, it must be addressed using
the GPIB address. The remote control address is factory-set to 20, but it can be
changed if it does not fit in the network environment. For remote control,
addresses 0 through 30 are allowed. The GPIB address is maintained after a
reset of the instrument settings.

To change the GPIB address

1. In the R&S FPS's mini display menu, navigate to "GPIB" > "GPIB address"
and press the ENTER key.

2. Enter the required address: Use the <Up Arrow> and <Down Arrow> keys to
scroll through the digits 1-10 and the <Left Arrow> and <Right Arrow> keys to

How to Log on to the Network

5.3 How to Log on to the Network

Windows 7 requires that users identify themselves by entering a user name and
password in a login window. You can set up two types of user accounts, either an
administrator account with unrestricted access to the computer/domain or a stan­dard user account with limited access. The instrument provides an auto-login
function for the administrator account, i.e. login with unrestricted access is carried
out automatically in the background. By default, the user name for the administra­tor account is "Instrument", and the user name for the standard user account is
"NormalUser". In both cases the initial password is "894129". You can change the
password in Windows 7 for any user at any time. Some administrative tasks
require administrator rights (e.g. firmware updates or the configuration of a LAN
network).

At the same time you log on to the operating system, you are automatically log­ged on to the network. As a prerequisite, the user name and the password must
be identical on the instrument and on the network.

5.3.1 How to Create Users

After the software for the network has been installed, the instrument issues an
error message the next time it is switched on because there is no user named
"instrument" (= default user ID for Windows 7 automatic login) in the network.
Thus, a matching user must be created in the R&S FPS and in the network, the
password must be adapted to the network password, and the automatic login
mechanism must then be deactivated.

In order to configure users for the R&S FPS, a controller pc or an external
monitor, mouse and keyboard must be connected to the R&S FPS. See

Chapter 5.6, "How to Set Up Remote Desktop", on page 69.

5.5 How to Start a Remote Control Session from a

PC

When you switch on the instrument, it is always in manual operation state ("local"
state) and can be operated via Remote Desktop from an external PC.

1. Send an addressed command (GTR - Go to Remote) from a controller to the
instrument.

The instrument is switched to remote control ("remote" state). Operation via
the soft front panel (on the Remote Desktop) is disabled. (The keys on the
R&S FPS remain enabled.) The instrument remains in the remote state until it
is reset to the manual state via the remote control interface.
Switching from manual operation to remote control and vice versa does not
affect the other instrument settings.

2. To obtain optimum performance during remote control, send the
SYSTem:DISPlay:UPDate OFF command to hide the display of results and
diagrams on the controller PC or external monitor (default setting in remote
control).

3. To enable manual operation via the soft front panel on the Remote Desktop
again, switch the instrument to local mode using the remote command GTL
(Go to Local), that is, deactivate the REN line of the remote control interface.

5.6 How to Set Up Remote Desktop

Remote Desktop is a Windows application which can be used to access and con­trol the instrument from a remote computer through a LAN connection. While the
instrument is in operation, the instrument uses the display on the remote com­puter, and Remote Desktop provides access to all of the applications, files, and
network resources of the instrument. Thus, remote operation of the R&S FPS is
possible.

How to Set Up Remote Desktop

With Windows 7, Remote Desktop Client is part of the operating system. For
other versions of Windows, Microsoft offers the Remote Desktop Client as an
add-on.

This section provides basic instructions on setting up the Remote Desktop for the
R&S FPS. For details refer to the Windows 7 operating system documentation.

5.6.1 How to Configure the R&S FPS for Remote Operation via

Remote Desktop

By default, the R&S FPS is configured to allow Remote Desktop access by
any user (except for the "SecureUser", see Chapter 5.6.5, "How to Add or

Remove Users to the Remote Desktop Users Group", on page 77), and to

use a fixed IP address.

To change the settings for remote operation, you must connect an external moni­tor, mouse and keyboard, or connect a controller PC and set up a Remote Desk­top connection with the default settings as described in Chapter 5.6.3, "How to

Start and Close the Remote Desktop", on page 74.

To change the settings for Remote Desktop access

To avoid problems, use a fixed IP address (see Chapter 5.2.2, "How to

Assign the IP Address", on page 59).

When a DHCP server is used, a new IP address is assigned each time the
instrument is restarted. This address must first be determined on the instru­ment itself. Thus, using a DHCP server is not suitable for remote operation
of the R&S FPS via Remote Desktop.

1.

Select the "Windows" icon in the toolbar to access the operating system of the
R&S FPS.

2. In the "Start" menu, select the "Control Panel" and then "System and Secur­ity".
