Windows Operating System
Manual operation using an external monitor and keyboard
Since the R&S FPS does not have a built-in measurement screen, it is recommended that you connect an external monitor to the instrument initially.
Thus, you can get familiar with the instrument and its manual operation
before using it in pure remote mode. This manual also describes in detail
how to operate the instrument manually using an external monitor and keyboard.
Preparing for Use
4.10 Windows Operating System
The instrument contains the Windows 10 operating system which has been configured according to the instrument's features and needs. Changes in the system
setup are only required when peripherals like a keyboard or a printer are installed
or if the network configuration does not comply with the default settings. After the
R&S FPS is started, the operating system boots and the instrument firmware is
started automatically.
Tested software
The drivers and programs used on the instrument under Windows 10 are adapted
to the instrument. Only install update software released by Rohde & Schwarz to
modify existing instrument software.
You can install additional software on the instrument; however, additional software can impair instrument function. Thus, run only programs that
Rohde & Schwarz has tested for compatibility with the instrument software.
The following program packages have been tested:
●
Symantec Endpoint Security – virus-protection software
●
FileShredder - for reliable deletion of files on the hard disk
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.

R&S®FPS
Windows Operating System
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. Rohde & Schwarz instruments are shipped with
the Windows firewall enabled and preconfigured in such a way that all ports and
connections for remote control are enabled.
Note that changing firewall settings requires administrator rights.
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 Windowsbased instruments, due to potentially degrading instrument performance. However, Rohde & Schwarz does recommend running it during non-critical hours.
Preparing for Use
For details and recommendations, see the following Rohde & Schwarz white
paper:

Preparing for Use
Logging On
All necessary system settings can be defined in the "Start > Settings" menu.
For required settings, refer to the Windows 10 documentation and to the hardware description.
4.11 Logging On
Windows 10 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
Some administrative tasks require administrator rights (e.g. the configuration of a
LAN network). Refer to the description of the basic instrument Setup ([Setup]
menu) to find out which functions are affected.
28Getting Started 1319.3362.02 ─ 10
R&S®FPS
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. You 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 4.15, "Protecting Data Using the Secure User
Mode", on page 33.
Passwords
Preparing for Use
Logging On
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. An administrator can change the password in Windows 10
for any user at any time via "Start > Settings > Account > SignIn Options > Password > Change".
Auto-login
When shipped, the instrument automatically logs on the default "Instrument" user
to Windows 10 (with full access) using the default password. This function is
active until an administrator explicitly deactivates it or changes the password.
29Getting Started 1319.3362.02 ─ 10
R&S®FPS
Changing the password and use of auto-login function
Note that when you change the default password, the default auto-login
function no longer works!
In this case, you must enter the new password manually to log on.
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 7.6, "How to Set Up Remote Desktop",
on page 82.
Be aware if the auto-login function is deactivated or does not work 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.
Preparing for Use
Logging On
Adapting the auto-login function to a new password
If you change the password that is used during auto-login, this function no longer
works. Adapt the settings for 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\user\AUTOLOGIN.REG file in any text editor (e.g. Notepad).
2. In the line "DefaultPassword"="894129", replace the default password
(894129) by the new password for automatic login.
3. Save the changes to the file.
4. In the Windows "Start" menu, select "Run".
The "Run" dialog box is displayed.
5. Enter the command C:\R_S\INSTR\USER\user\AUTOLOGIN.REG.

Performing a Self-Alignment
Preparing for Use
4.13 Performing a Self-Alignment
When strong temperature changes occur in the environment of the R&S FPS, or
after updating the firmware, you have to perform a self-alignment to align the data
to a reference source.
During self-alignment, do not connect a signal to the RF input connector. Running
a self-alignment with a signal connected to the RF input can lead to false measurement results.
To perform a self alignment directly on the R&S FPS
► In the R&S FPS's mini display, navigate to "System commands" > "Self align".
For details on working with the mini display, see Chapter 6, "Mini Display",
on page 47.
To perform a self alignment via Remote Desktop
Performing a self alignment via Remote Desktop requires a controller PC to be
connected, see Chapter 7.6, "How to Set Up Remote Desktop", on page 82.
Before performing this functional test, make sure that the instrument has reached
its operating temperature (for details, refer to the data sheet).
A message in the status bar ( "Instrument warming up..." ) indicates that the operating temperature has not yet been reached.
Depending on the installation settings, an automatic self-alignment is performed
each time the instrument is switched on. A dialog is displayed indicating how
much warm-up time is still required before self-alignment can be performed.
1. Select the [SETUP] key in the soft front panel on the Remote Desktop.
2. Select the "Alignment" softkey.
3. Select the "Start Self Alignment" button in the "Alignment" dialog box.
Once the system correction values have been calculated successfully, a message is displayed.
To display the alignment results again later

Protecting Data Using the Secure User Mode
Preparing for Use
4.14 Considerations for Test Setup
Cable selection and electromagnetic interference (EMI)
Electromagnetic interference (EMI) can affect the measurement results.
To suppress electromagnetic radiation during operation:
●
Use high-quality shielded cables, for example, double-shielded RF and LAN
cables.
●
Always terminate open cable ends.
●
Ensure that connected external devices comply with EMC regulations.
Preventing electrostatic discharge (ESD)
Electrostatic discharge is most likely to occur when you connect or disconnect a
DUT.
► NOTICE! Risk of electrostatic discharge. Electrostatic discharge can damage
the electronic components of the product and the device under test (DUT).
Ground yourself to prevent electrostatic discharge damage:
a) Use a wrist strap and cord to connect yourself to ground.
b) Use a conductive floor mat and heel strap combination.
Signal input and output levels
Information on signal levels is provided in the data sheet. Keep the signal levels
within the specified ranges to avoid damage to the R&S FPS and connected devices.
4.15 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
data created during operation.
33Getting Started 1319.3362.02 ─ 10
R&S®FPS
Protecting Data Using the Secure User Mode
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 operating system files
●
Firmware shutdown files containing information on last instrument state
●
Self-alignment data
●
General instrument settings such as the IP address
●
Measurement settings
●
User data created during operation
Preparing for Use
●
Any data created by other applications installed on the R&S FPS, for example,
text editors (Notepad), the clipboard, or drawing tools.
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.
This includes predefined instrument settings, transducer factors and self-alignment data.
34Getting Started 1319.3362.02 ─ 10
R&S®FPS
Protecting Data Using the Secure User Mode
Self-alignment data
Note that self-alignment data becomes invalid with time and due to temperature changes. Therefore, to achieve optimal accuracy, it can 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
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.
Preparing for Use
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 7.6.5, "How to Add or Remove
Users to the Remote Desktop Users Group", on page 88). 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 mini 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 auto-login function. While
the secure user mode is active, a message is displayed in the status bar at the
bottom of the screen, and in the mini display "SecUsr" is displayed.
To deactivate the secure user mode, the "SecureUser" must log off and a user
with administrator rights must log on.

Protecting Data Using the Secure User Mode
Switching users when using the auto-login function
In the "Start" menu, select the arrow next to the "Shut down" button and
then "Log off".
The "Login" dialog box is displayed, in which you can enter the different user
account name and password.
The secure user mode setting and auto-login is automatically deactivated when
another user logs on. The "SecureUser" is no longer available.
For users with administrator rights, the secure user mode setting is available in
the general system configuration settings ([Setup] key > "System Configuration"
softkey > "Config" tab > "Secure User Mode": "ON", see the R&S FPS user manual).
Alternatively, you can activate or deactivate the secure user function via the mini
display (see "Enable SecureUser/Disable SecureUser" on page 51. In this case,
enter the administrator ("Instrument" user) password.
Preparing for Use

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 warmup time (see data sheet).
5.3.2 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

Controlling the R&S FPS Remotely
7 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 7.2, "How to Con-
figure a Network", on page 70)
●
Using the web browser interface in a LAN network (see Chapter 7.2.3, "How
to Configure the LAN Using the Web Browser Interface", on page 73)
●
Using the Windows Remote Desktop application in a LAN network (see Chap-
ter 7.6, "How to Set Up Remote Desktop", on page 82)
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 7.2, "How to Configure a Network", on page 70 and Chapter 7.5,
"How to Start a Remote Control Session from a PC", on page 81.
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,
57Getting Started 1319.3362.02 ─ 10
R&S®FPS
Controlling the R&S FPS Remotely

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.
7.1.1 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 7.1.4, "VISA Libraries", on page 69 for
details.

R&S®FPS
The R&S FPS supports various LAN protocols such as VXI11, 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
●
The DNS host name is FPS7-123456; the valid resource string using HiSLIP
is:
TCPIP::FPS7-123456::hislip0
●
A raw socket connection can be established using:
TCPIP::192.1.2.3::5025::SOCKET
60Getting Started 1319.3362.02 ─ 10
R&S®FPS
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 the resource string.
For details on configuring the LAN connection, see Chapter 7.2, "How to Config-
ure a Network", on page 70.

7.1.1.1 VXI-11 Protocol
Controlling the R&S FPS Remotely
Remote Control Interfaces and Protocols
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.
7.1.1.2 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
61Getting Started 1319.3362.02 ─ 10
R&S®FPS
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 Instrument Control with HiSLIP
7.1.1.3 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.
Controlling the R&S FPS Remotely
Remote Control Interfaces and Protocols
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.
7.1.1.4 LAN Web Browser Interface
The LAN web browser interface allows for easy configuration of the LAN and
remote control of the R&S FPS without additional installation requirements.
The instrument's LAN web browser interface works correctly with all W3C compliant browsers.
Via the web browser interface to the R&S FPS you can control the instrument
remotely from another PC. Manual instrument controls are available via the front

7.1.2 GPIB Interface (IEC 625/IEEE 418 Bus Interface)
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 7.2.4, "How to Change the GPIB Instrument Address",
on page 76). You can set the GPIB address and the ID response string. The
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.

7.1.2.1 GPIB Interface Messages
Interface messages are transmitted to the instrument on the data lines, with the
attention line (ATN) being active (LOW). They are used for communication
between the controller and the instrument and can only be sent by a computer
which has the function of a GPIB bus controller. GPIB interface messages can be
further subdivided into:
●
Universal commands: act on all instruments connected to the GPIB bus
without previous addressing
●
Addressed commands: only act on instruments previously addressed as listeners
The following figure provides an overview of the available communication lines
used by the GPIB interface.

7.2 How to Configure a Network
Risk of network failure
Consult your network administrator before performing the following tasks:
●
Connecting the instrument to the network
●
Configuring the network
●
Changing IP addresses
●
Exchanging hardware
Errors can 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 10 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 7.6, "How to Set
Up Remote Desktop", on page 82
●
To connect external network devices (e.g. printers)
●
To transfer data from a remote computer and back, e.g. using network folders
70Getting Started 1319.3362.02 ─ 10
R&S®FPS
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 10 help system.

How to Configure a Network
7.2.1 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 7.2.2, "How to Assign the IP Address", on page 72.
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 10 automatically detects the
network connection and activates the required drivers.
71Getting Started 1319.3362.02 ─ 10

The network card can be operated with a 1 GBit Ethernet IEEE 802.3u interface.
Controlling the R&S FPS Remotely
How to Configure a Network
7.2.2 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.
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.

How to Configure a Network
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.
●
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 instrument and another
device. The ping command uses the ICMP echo request and echo reply packets

7.5 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.

How to Set Up Remote Desktop
7.6 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.
With Windows 10, 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 10 operating system documentation.
7.6.1 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 7.6.5, "How to Add or
Remove Users to the Remote Desktop Users Group", on page 88).
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 7.6.3, "How to
Start and Close the Remote Desktop", on page 86.

8 Operating the Instrument in Manual
Mode
The R&S FPS is completely remote-controlled; it does not provide a display for
manual measurement control. The mini display on the front panel of the R&S FPS
allows only for very basic instrument configuration (see Chapter 6, "Mini Display",
on page 47).
However, although the R&S FPS does not have a built-in display for manual measurement control, it is possible to operate it interactively in manual mode using a
graphical user interface on an external monitor or a controller PC.
It is recommended that you use the manual mode initially to get familiar with the
instrument and its functions before using it in pure remote mode. Thus, this section describes in detail how to operate the instrument manually using a controller
PC and mouse, or an external monitor, mouse and keyboard. It describes what
kind of information is displayed in the diagram area, how to use the soft front
panel keys and other interface elements, and how to use the Online Help.
