4 Getting Started
4.1 Putting the Analyzer into Operation
This section describes the basic steps to be taken when setting up the analyzer for the
first time.
Simple measurement examples are provided in Chapter 4.4, "Performing Measure-
ments", on page 56; for a description of the operating concept refer to Chapter 4.3,
"Operating the Instrument", on page 29. For all background and reference informa-
tion concerning manual and remote control of the instrument, refer to your analyzer's
help system or user manual. A more detailed description of the hardware connectors
and interfaces is also part of the help system or user manual.
Risk of injury due to disregarding safety information
Observe the information on appropriate operating conditions provided in the data sheet
to prevent personal injury or damage to the instrument. Read and observe the basic
safety instructions provided with the instrument, in addition to the safety instructions in
the following sections. In particular:
●Do not open the instrument casing.
4.1.1 Unpacking and Checking the Instrument
Check the equipment for completeness using the delivery note and the accessory lists
for the various items. If you notice any damage, immediately contact the carrier who
delivered the instrument.
Packing material
Retain the original packing material. If the instrument needs to be transported or ship-
ped later, you can use the material to protect the control elements and connectors.
Risk of injury during transportation
The carrying handles at the front and side of the casing are designed to lift or carry the
instrument. Do not apply excessive force to the handles. If a handle is ripped off, the
falling instrument can cause injury.
As the R&S ZNA is very heavy (over 30 kg fully equipped), it must always be carried
by two people using both carrying handles to avoid personal injury or damage to the
instrument.

4.1.2 Positioning the Instrument
The network analyzer is designed for use under laboratory conditions, either on a
bench top or in a rack.
Risk of instrument damage due to inappropriate operating conditions
An unsuitable operating site or test setup can damage the instrument and connected
devices. Before switching on the instrument, observe the information on appropriate
operating conditions provided in the data sheet. In particular, ensure the following:
●All fan openings are unobstructed and the airflow perforations are unimpeded. A
minimum distance of 10 cm to other objects is recommended.
●The instrument is dry and shows no sign of condensation.
●The instrument is positioned as described in the following sections.
●The ambient temperature does not exceed the range specified in the data sheet.
●Signal levels at the input connectors are all within the specified ranges.
●Signal outputs are connected correctly and are not overloaded.
Instrument damage caused by electrostatic discharge
Electrostatic discharge (ESD) can damage the electronic components of the instrument
and the device under test (DUT). Electrostatic discharge is most likely to occur when
you connect or disconnect a DUT or test fixture to the instrument's test ports. To pre-
vent electrostatic discharge, use a wrist strap and cord and connect yourself to the
ground, or use a conductive floor mat and heel strap combination.
During operation, if the firmware observes a serious unexpected disturbance (e.g. due
to ESD), it resets all hardware components to ensure proper instrument functioning. It
then restores the user settings to the state before the disturbance and indicates the
foregone hardware reset by an "Hardware communication problem [...]" information
popup.
4.1.3 Bench Top Operation
If the analyzer is operated on a bench top, the surface must be flat. The instrument can
be used in horizontal or vertical position, standing on its feet, or with the support feet
on the bottom expanded.
Putting the Analyzer into Operation

Getting Started
R&S® ZNA
13User Manual 1178.6462.02 ─ 16
Risk of injury if feet are folded out
The feet can fold in if they are not folded out completely or if the instrument is shifted.
Collapsing feet can cause injury or damage the instrument.
●Fold the feet completely in or out to ensure stability of the instrument. Never shift
the instrument when the feet are folded out.
●When the feet are folded out, do not work under the instrument or place anything
underneath.
●The feet can break if they are overloaded. The overall load on the folded-out feet
must not exceed 500 N.
4.1.4 Operation in a 19" Rack
The R&S ZNA can be mounted in 19" racks using the adapter R&S ZZA-KN6 (order
number 1332.4498.02). Proceed according to the mounting instructions supplied with
the rack adapter.
Risk of instrument damage due to insufficient airflow in a rack
If you mount several instruments in a rack, you need an efficient ventilation concept to
ensure that the instruments do not overheat. Insufficient airflow for a longer period can
disturb the operation and even cause damage.
4.1.5 EMI Suppression
Electromagnetic Interference (EMI) can affect the measurement results.
To suppress generated Electromagnetic Interference:
●Use suitable shielded cables of high quality (see table below)
●Always terminate open cable ends
●Note the EMC classification in the data sheet

PCIe Standard cable
USB Standard cables, length ≤ 3m
4.1.6 Connecting the Analyzer to the AC Supply
The network analyzer is automatically adapted to the AC supply voltage, which must
be in the range of 100 V to 240 V at 50 Hz to 60 Hz. A line frequency of 400 Hz is also
supported.
The mains connector is located in the upper part of the rear panel (see Chapter 4.2.2,
"Rear Panel", on page 26).
► Connect the network analyzer to the AC power source using the AC power cable
delivered with the instrument.
The maximum power consumption and the typical power consumption of the individual
analyzer models are listed in the data sheet.
4.1.7 Starting the Analyzer and Shutting Down
The AC power switch is located in the upper part of the rear panel, above the mains
connector; see Chapter 4.2.2, "Rear Panel", on page 26.
To start the analyzer, proceed as follows:
1. Switch the AC power switch to position I (On).
Putting the Analyzer into Operation

Getting Started
R&S® ZNA
15User Manual 1178.6462.02 ─ 16
After power-on, the analyzer automatically goes to standby or ready state, depend-
ing on the state of the standby toggle key at the front panel when the instrument
was switched off last time.
2. If necessary, press the standby toggle key on the front panel to switch the instru-
ment to ready state.
The instrument automatically performs a system check, boots the Windows® oper-
ating system and then starts the vector network analyzer (VNA) application. If it
was terminated regularly, the VNA application restores all recall sets and instru-
ment settings of the previous analyzer session.
To shut down the analyzer, proceed as follows:
1. Press the standby key.
Pressing the standby key causes the instrument to save all loaded recall sets, to
close the VNA application, to shut down Windows®, and to go to standby state. Of
course, you can also perform these steps manually, like in any Windows session.
2. If desired, set the AC power switch to position O (Off).
Risk of data loss
It is recommended to switch the analyzer to standby state before disconnecting it from
the AC supply. If you set the power switch to 0 while the VNA application is still run-
ning, you lose the current settings. Moreover, loss of program data cannot be excluded
if the application is terminated improperly.
The AC power switch can be permanently on. It is recommendable, however, to switch
it off if the instrument is not used for some time. When you switch the instrument back
on, be sure to comply with the extended warm-up phase specified in the data sheet.
To guarantee the specified functionality, after turning off the R&S ZNA, you have to wait
for at least 10 seconds before turning it on again. This rule applies to both the AC
power off and the standby state.
4.1.8 Standby and Ready State
The standby toggle key is located in the bottom left corner of the front panel.
The standby power only supplies the power switch circuits and the optional high preci-
sion quartz (R&S ZNA-B4, "Precision Oven Quartz Frequency Reference"). In this
state, it is safe to switch the AC power off and disconnect the instrument from the
power supply. In ready state, all modules are power-supplied. When switched to ready
state, the analyzer initiates its startup procedure.

Printer driver installation
If necessary, the printer driver installation is initiated using the operating system's "Add
Printer Wizard". The wizard is self-explanatory. A printer driver must be installed only
once.
A great variety of printer drivers is available on the analyzer. To obtain the complete
list, select "Settings" > "Devices" > "Printers & scanners" from the Windows® "Start"
menu.
To access Windows®, use the button in the toolbar of the application window.
You can load updated and improved driver versions or new drivers from an installation
disk, USB memory stick or another external storage medium. Alternatively, if the ana-
lyzer is integrated in a network, you can install driver data stored in a network directory.
In either case, use the "Add Printer" wizard to complete the installation.
Printer configuration
Use the "Printer Setup" dialog of the firmware (System – [File Print] > "Print" >
"Print...") or the Windows® printer management to configure the printer properties and
printing preferences.

4.1.9.5 Connecting a LAN Cable
A LAN cable can be connected to the LAN connector on the rear panel of the analyzer.
To establish a LAN connection, proceed as follows:
1. Refer to Chapter 11.1.3.1, "Assigning an IP Address", on page 1537.
2. Connect a CAT6 or CAT7 LAN cable to the LAN port.
The LAN port of the analyzer is an auto-crossover Ethernet port. You can connect it to
a network, but you can also set up a direct connection to a computer or another instru-
ment. For both connection types, you can use either crossover or straight through
(patch) cables.
The IP address information is displayed in the System – [Setup] > "Remote Settings"
softtool tab.
4.1.9.6 Connecting a USB Cable for Remote Control
The R&S ZNA can also be remote controlled via USB. To prepare for remote control
operation, connect a suitable USB cable to the type B "USB Device" port on the rear
panel of the instrument. With direct connection to a master device, a connecting cable
A-B (plug type A onto plug type B) must be used.
For more information, refer to Chapter 7.1, "Introduction to Remote Control",
on page 789.
4.1.10 Minimizing the VNA Application
With a minimized VNA application, you can access your analyzer's Windows® desktop
or run other applications.
To exit the default full-screen mode of the VNA application, deselect System – [Display]
> "View Bar" > "Title Bar Task Bar". Then use the standard Windows® titlebar functions
to minimize/maximize/close the application window.
To start the VNA application with a minimized window
1. Right-click the Vector Network Analyzer shortcut icon on the desktop and open the
"Properties" dialog.
2. In the "Shortcut" tab, select "Run: Minimized".
