1.1.2.1 Test Ports
N-connectors, numbered 1, 2, ... The test ports serve as outputs for the RF stimulus
signal and as inputs for the measured RF signals from the DUT (response signals). Up
to 6 additional test ports can be purchased as options (order no. 1300.1506.03 to
1300.1506.08; see detailed ordering information in the product brochure).
●With a single test port, it is possible to generate a stimulus signal and measure the
response signal in reflection.
●With 2 or more test ports, it is possible to perform full two-port or multiport mea-
surements; see chapter 3.3.1, "S-Parameters", on page 67. Note that pairs of test
ports (1 and 2, 3 and 4 etc.) are supplied by a common generator.
●Each test port may be complemented by three pairs of additional connectors used
to test high power devices and extend the dynamic range, see chapter 1.1.2.4,
"Direct Generator and Receiver Access", on page 10.
Maximum input levels
The maximum input levels at all test ports according to the front panel labeling or the
data sheet must not be exceeded.
In addition, the maximum input voltages of the other input connectors at the front and
rear panel must not be exceeded.
It is recommended to use a torque wrench when screwing RF cables on the test port
connectors. Standard IEEE 287 specifies a torque of (1.5 ± 0.2) Nm for N connectors.
1.1.2.2 USB Connectors
Double Universal Serial Bus connector of type A (master USB), used to connect e.g a
keyboard, mouse or other pointing devices, the Calibration Unit (accessory R&S ZV-
Z5x), a printer or an external storage device (USB stick, CD-ROM drive etc.).
To control external devices (e.g. power meters, generators) via USB connector, a VISA
installation on the network analyzer is required. Use the USB-to-IEC/IEEE Adapter
(option R&S ZVAB-B44) to control devices equipped with a GPIB interface.
The length of passive connecting USB cables should not exceed 1 m. The maximum
current per USB port is 500 mA. See also chapter 1.3.5, "EMI Suppression",
on page 15.

R&S ZVAB-B44 on network analyzers with FMR7/6 and FMR9
The driver software of the USB-to-IEC/IEEE Adapter (option R&S ZVAB-B44) must be
installed on the network analyzer. On analyzers equipped with an FMR7/6 or FMR9
front module controller, this installation disables GPIB control from an external PC. A
reinstallation of the NWA firmware (e.g. in repair mode) will resolve the problem; see
chapter 1.9, "Firmware Update", on page 23.
1.1.2.3 Ground Connector
Connector providing the ground of the analyzer's supply voltage.
Electrostatic discharge
Electrostatic discharge (ESD) may cause damage to the electronic components of the
DUT and the analyzer. Use the wrist strap and cord supplied with the instrument to
connect yourself to the GND connector.
1.1.2.4 Direct Generator and Receiver Access
Option R&S ZVT<n>-B16, Direct Generator/Receiver Access, provides 3 pairs of SMA
connectors for each test port. <n> corresponds to the network analyzer type. For
detailed ordering information refer to the product brochure. See also section Converter
Control in the help system of your network analyzer.
The connectors give direct access to various RF input and output signals. They can be
used to insert external components (e.g. external signal separating devices, power
amplifiers, a ZVAX extension unit etc.) into the signal path in order to develop custom
measurements, e.g. to test high power devices and extend the dynamic range. If no
external components are connected, each OUT/IN loop should be closed using a
jumper.
●The SOURCE OUT signal comes from the internal RF signal source. The
SOURCE IN signal goes to the test port. A power amplifier can be inserted
between SOURCE OUT and SOURCE IN in order to boost the test port power.
●The REF OUT signal comes from the coupler and provides the reference signal.
The REF IN signal goes to the receiver input for the reference signal.
●The MEAS OUT signal comes from the coupler and provides the received (mea-
sured) signal. The MEAS IN signal goes to the receiver input for the measured sig-
nal.

Input signals
The maximum RF input levels at all SMA inputs according to the front panel labeling or
the data sheet must not be exceeded.
In addition, it is important that the signal fed in at the SMA inputs contains no DC off-
set, as this may impair the measurements and even cause damage to the instrument.
1.2 Rear Panel Tour
This section gives an overview of the rear panel controls and connectors of the net-
work analyzer.
Fig. 1-2: R&S ZVT rear view
The rear connectors are described in detail in the annex "Hardware Interfaces" in the
help system.

USER CONTROL connector in order to avoid spurious input signals which may
cause undesirable events. This is of particular importance for the external trigger
input (pin no. 2) if the EXT TRIGGER input is used.
●USB: Use double-shielded USB cables and ensure that external USB devices com-
ply with EMC regulations.
●GPIB (IEEE/IEC 625): Use a shielded GPIB cable.
●LAN: Use CAT6 or CAT7 cables.
●Test ports: For instruments with 3.5 mm connector types, use double-shielded
measurement cables.
The use of external accessories for the network analyzers may introduce additional
connector, cable, and cable length requirements. Refer to the relevant documentation.
1.3.6 Connecting the Analyzer to the AC Supply
The network analyzer is automatically adapted to the AC supply voltage supplied. The
supply voltage must be in the range 100 V to 240 V; 50 Hz to 60 Hz. The mains con-
nector is located at the bottom left corner of the rear panel.
► Connect the network analyzer to the AC power source using the AC power cable
delivered with the instrument.
The maximum power consumption of the analyzer is 650 W. The typical power con-
sumption is listed in the "Specifications".
The network analyzer is protected by two fuses as specified on the label on the power
supply. The fuses are located on an AC Fuse Board (order no. 1145.3906.02) which
must be replaced to change the fuses. Replacing the AC Fuse Board requires opening
the instrument and is described in the service manual.
1.3.7 Power on and off
The mains connector is located at the bottom left corner of the rear panel.
► To turn the power on or off, press the AC power switch to position I (On) or 0 (Off).
Putting the Analyzer into Operation

Preparing the Analyzer for Use
R&S® ZVT
16Getting Started 1300.0045.62 ─ 10
After power-on, the analyzer is in standby or ready state, (see chapter 1.3.8, "Standby
and Ready State", on page 16) depending on the state of the STANDBY toggle
switch at the front panel when the instrument was switched off for the last time.
The AC power switch can be permanently on. Switching off is required only if the
instrument must be completely removed from the AC power supply.
1.3.8 Standby and Ready State
The STANDBY toggle switch is located in the bottom left corner of the front panel.
► After switching on the AC power (see chapter 1.3.7, "Power on and off",
on page 15) press the STANDBY key briefly to switch the analyzer from the
standby to ready state or vice versa.
●In standby state, the right, amber LED is on. The standby power only supplies the
power switch circuits and the optional oven quartz (OCXO, 10 MHz reference oscil-
lator, option R&S ZVAB-B4, order no. 1164.1757.02). In this state it is safe to
switch off the AC power and disconnect the instrument from the power supply.
●In ready state, the left, green LED is on. The analyzer is ready for operation. All
modules are power-supplied and the analyzer initiates its startup procedure.
Shock hazard
The instrument is still power-supplied while it is in standby mode.
1.3.9 Replacing Fuses
The DC inputs PORT BIAS at the rear panel are each protected by a fuse IEC 127 - F
250 L (250 mA quick acting).
► To replace the fuses open the fuse holder by slightly turning the lid counterclock-
wise.
Replacement fuses are provided with the instrument.
1.4 Starting the Analyzer and Shutting Down
The analyzer can be controlled in two alternative ways:
●With a Remote Desktop connection through a Local Area Network. See chap-
ter 1.8, "Remote Desktop Connection", on page 22.
Starting the Analyzer and Shutting Down

Preparing the Analyzer for Use
R&S® ZVT
17Getting Started 1300.0045.62 ─ 10
●With an external monitor in combination with a mouse. See chapter 1.6, "Connect-
ing External Accessories", on page 18.
To start the analyzer, proceed as follows:
1. Make sure that the instrument is connected to the AC power supply and the power
switch on the rear panel is in position I (On).
2. If necessary, press the STANDBY toggle switch on the front panel to switch the
instrument to ready state (the green LED is on).
In ready state, the analyzer automatically performs a system check, boots the Win-
dows® operating system and then starts the network analyzer (NWA) application. If the
last analyzer session was terminated regularly, the NWA application uses the last
setup with all instrument settings.
To shut down the analyzer, proceed as follows:
1. Press the STANDBY key to save the current setup, close the NWA application,
shut down Windows® and set the instrument to standby state. Of course you can
also perform this procedure step by step like in any Windows session.
2. If desired, set the AC power switch to position 0 (Off).
Risk of data loss
It is strongly recommended to switch the analyzer to standby state before disconnect-
ing it from the AC supply. If you set the power switch to 0 while the NWA application is
still running, you will lose the current settings. Moreover, loss of program data can not
be excluded if the application is terminated improperly.
Minimizing the NWA application
With a minimized NWA application, you can access your analyzer's Windows® desktop
or run other applications. To start the NWA application with a minimized window on a
continuing basis, right-click the NWA shortcut icon on the desktop and open the "Prop-
erties" dialog. In the "Shortcut" tab, select "Run: Minimized".
After a software update the NWA application is started with a maximized window
again. Moreover, if a second NWA application is started after a first, minimized applica-
tion, this will cause the first application to come to the foreground.
1.5 Windows Operating System
The analyzer is equipped with a Windows XP or Windows 7 operating system that has
been configured according to the instrument's features and needs.
Windows Operating System

Preparing the Analyzer for Use
R&S® ZVT
18Getting Started 1300.0045.62 ─ 10
Support for Windows 7 was added with FW version 3.50 and requires the analyzer to
be equipped with the new CPU board FMR11.
Upgrade kits from FMR6/7/9 to FMR11 with Windows 7 are available as option
R&S ZVA-U116. Note however that FMR11 is not supported with Windows XP.
Changes in the system configuration can be necessary in order to:
●Customize the properties of the external accessories connected to the analyzer,
e.g. the screen resolution of a connected monitor
●Establish a LAN connection
●Call up additional software tools
Modifications of the operating system
The operating system is adapted to the network analyzer. To avoid impairment of
instrument functions, only change the settings described in this manual. Existing soft-
ware must be modified only with update software released by Rohde & Schwarz. Like-
wise, only programs authorized by Rohde & Schwarz for use on the instrument must
be executed.
The "Start" menu of the operating system is accessed by pressing the Windows key on
the external keyboard or on the hardkey bar of the GUI. All necessary settings can be
accessed from the "Start" menu, in particular from the Control Panel.
1.6 Connecting External Accessories
The equivalent USB ports on the front and rear panel of the analyzer can be used to
connect a variety of accessories:
●A mouse simplifies operation of the instrument using the controls and dialogs of
the Graphical User Interface (GUI).
●A keyboard simplifies the entry of data; the default input language is English – US.
●A printer generates hard copies of the GUI and the measurement results. When
printing a copy ("File – Print"), the analyzer checks whether a printer is connected
and turned on and whether the appropriate printer driver is installed.
If required, printer driver installation is initiated using the Windows "Add Printer"
wizard. The wizard is self-explanatory. A printer driver needs to be installed only
once, even though the printer may be temporarily removed from the analyzer.
It is safe to connect or disconnect mouse, keyboard or printer during the measurement.
A standard VGA monitor or LCD display can be connected to the 15-pole Sub-Min-D
MONITOR connector on the rear panel of the analyzer.
Connecting External Accessories

Preparing the Analyzer for Use
R&S® ZVT
19Getting Started 1300.0045.62 ─ 10
It displays the magnified Graphical User Interface (GUI) with all diagram areas and
controls and the "Hardkey Bar" with key shortcuts for the most important menus and
submenus. With an additional mouse connected to the analyzer, it is possible to control
the analyzer from the GUI.
For instruments running Windows 7 the external monitor port is automatically enabled
at firmware startup.
Safety aspects
The monitor must be connected while the instrument is switched off (or in standby
mode). Otherwise correct operation can not be guaranteed.
Typically mouse, keyboard and monitor are plug & play devices, i.e. they are automati-
cally detected by the operating system. If necessary, use standard Windows techni-
ques (such as the "Add Printer " wizard or the device properties pages accessible via
Windows Control Panel) to install missing or enhanced device drivers and to configure
connected devices.
1.7 Connecting to a LAN
A LAN connection is used to integrate the analyzer into a home/company network. This
offers several applications, e.g.:
●Transfer data between a controller and the analyzer, e.g. in order run a remote
control program.
●Control the measurement from a remote computer using the Remote Desktop
application.
●Use external network devices (e.g. printers).
Virus protection
An efficient virus protection is a prerequisite for secure operation in the network. Never
connect your analyzer to an unprotected network because this may cause damage to
the instrument software.

20Getting Started 1300.0045.62 ─ 10
1.7.1 Physical LAN Connection
A LAN cable can be connected to one of the LAN connectors on the rear panel of the
analyzer. To establish a LAN connection proceed as follows:
1. Refer to section TCP/IP Configutation and learn how to avoid connection errors.
2. Connect a CAT6 or CAT7 RJ-45 (LAN, Ethernet) cable to one of the LAN ports.
The LAN ports of the analyzer are auto-crossover Ethernet ports. You can connect
them to a network that is equipped with Ethernet hardware (hub, switch, router), but
you can also set up a direct connection to a computer or another test instrument. For
both connection types, you can use either crossover or standard straight-through
Ethernet cables.
1.7.2 TCP/IP Configutation
Depending on the network capacities, the TCP/IP configuration for the analyzer can be
obtained in different ways.
●If the network supports dynamic TCP/IP configuration using the Dynamic Host
Configuration Protocol (DHCP), the configuration can be assigned automatically.
●If the network does not support DHCP, or if the analyzer is set to use manual
TCP/IP configuration, the configuration must be entered manually.
The active TCP/IP configuration is displayed in the "Instrument Information" section of
the"Info > Setup Info" dialog.
By default, the analyzer is configured to use dynamic TCP/IP configuration. This
means that it is safe to establish a physical connection to the LAN without any previous
analyzer configuration.
Manual TCP/IP configuration
If your network does not support DHCP, or if you choose to disable dynamic TCP/IP
configuration, you must enter a valid TCP/IP configuration before connecting the ana-
lyzer to the LAN. Contact your network administrator, because connection errors can
affect the entire network.
For more information refer to the Windows "Help and Support Center".
To disable dynamic TCP/IP configuration and enter the TCP/IP address information
manually proceed as follows:
1. Obtain the IP address and subnet mask for the analyzer and the IP address for the
local default gateway from your network administrator. If needed, also obtain the
name of your DNS domain and the IP addresses of the DNS and WINS servers on
