bered 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).
●With a single test port, it is possible to generate a stimulus signal and measure the
response signal in reflection.
●With 2, 3 or 4 test ports, it is possible to perform full two-port, 3-port or 4-port meas-
urements; see chapter 3.3.1, "S-Parameters", on page 74. Note that pairs of test
ports (1and 2, 3 and 4) are supplied by a common generator (exception: R&S ZVA67).
Front Panel Tour

Preparing the Analyzer for Use
R&S® ZVA
13Quick Start Guide 1145.1090.62 ─ 10
●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 1.1.7.4, "Direct
Generator and Receiver Access", on page 14.
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.
The three LEDs above each test port indicate the connector state:
●The amber LED is on while the connector is used as a source port.
●The green LED is on while the connector is used as a bidirectional (source and
receive) port.
●The blue LED is on while the connector is used as a receive port.
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,
(0.9 ± 0.1) Nm for the microwave connector types.
1.1.7.2 USB Connector
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 19.

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 con-
nect yourself to the GND connector.
1.1.7.4 Direct Generator and Receiver Access
Option R&S ZVA<n>-B16, Direct Generator/Receiver Access, provides 3 pairs of SMA
connectors (or smaller connectors, for microwave analyzers) for each test port. <n> cor-
responds 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 ampli-
fiers, a ZVAX extension unit etc.) into the signal path in order to develop custom meas-
urements, 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 (measured)
signal. The MEAS IN signal goes to the receiver input for the measured signal.
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 offset,
as this may impair the measurements and even cause damage to the instrument.
1.1.8 Additional Hardware Options
The following hardware options can be mounted on the right of the NAVIGATION and
SUPPORT keypads:
●Option R&S ZVA-B18, Removable Hard Disk, replaces the internal hard disk by a
removable compact flash card. The compact flash card can be inserted at the front
panel of the instrument. To ensure failure-free operation, avoid placing external
cables close to the compact flash card.

Danger of injury
The feet may fold in if they are not folded out completely or if the instrument is shifted.
The feet may break if they are overloaded. Fold the feet completely in or completely out
to ensure stability of the instrument and personal safety. To avoid injuries, never shift the
instrument when its feet are folded out.
The overall load (the instrument's own weight plus that of the instruments stacked on top
of it) on the folded-out feet must not exceed 500 N.
Place the instrument on a stable surface. Secure the instruments stacked on top of it
against slipping (e.g. by locking their feet on the top front frame). When the instrument is
standing on its folded-out feet, do not work under the instrument and do not put anything
under it, otherwise injuries or material damage could occur.

The instrument can be used in each of the positions shown here.
1.3.4 Operation in a 19" Rack
Using the adapter R&S ZZA-611 (order number 1096.3302.00) the instrument can be
mounted in 19" racks according to the mounting instructions supplied with the rack
adapter.
Avoid overheating
●Allow for sufficient air supply in the rack.
●Make sure that there is sufficient space between the ventilation holes and the rack
casing.
1.3.5 EMI Suppression
To suppress generated Electromagnetic Interference (EMI), operate the instrument only
while it is closed, with all shielding covers fitted. Note the EMC classification in the data
sheet.
Use appropriate shielded cables to ensure successful control of electromagnetic radiation
during operation, especially for the following connector types:
●BNC rear panel connectors (10 MHz REF, EXT. TRIGGER): Use double shielded
cables and terminate open cable ends with 50 Ω.
●USER CONTROL: Use only well shielded cables or disconnect the input pins of the
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 comply
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 and smaller connector types (2.92 mm, 2.4
mm ...), use double-shielded measurement cables.
The use of external accessories for the network analyzers may introduce additional con-
nector, 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 connector
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 450 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).
After power-on, the analyzer is in standby or ready state, (see chapter 1.3.8, "Standby
and Ready State", on page 21) 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 instru-
ment must be completely removed from the AC power supply.
