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 prevent electrostatic discharge, use a wrist strap
and cord and connect yourself to the ground, or use a conductive floor mat
and heel strap combination.
If you are working in an environment where strong ESD discharges are pos-
sible, Rohde & Schwarz recommends using a broadband limiter R&S ZN-
B13 (stock number 1303.7840.02) at each port of your R&S ZNL.
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 infor-
mation on appropriate operating conditions provided in the data sheet. In
particular, ensure the following:
●All fan openings are unobstructed and the airflow perforations are unim-
peded. 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

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.
Portable operation
An optional carrying bag designed specifically for the R&S ZNL allows you to pro-
tect the instrument while working in the field. The bag includes ventilation areas at
the position of the ventilation outlets in the casing to ensure air circulation. The
transparent cover allows you to operate the instrument without removing it from
the bag. With the help of the optional vest holster you can carry the R&S ZNL in
its bag and keep your hands free. Together with the optional battery pack (see
Chapter 4.1.7, "Connecting an Optional Battery Pack (R&S FPL1-B31)",
on page 18), and packed in the dedicated carrying bag, the R&S ZNL is ideally
suited for operation directly in the field, even in rough environments.

4.1.4 Connecting the AC Power
The R&S ZNL is equipped with an AC power supply connector. The R&S ZNL can
be used with different AC power voltages and adapts itself automatically to it.
Refer to the datasheet for the requirements of voltage and frequency. The AC
power connector is located on the rear panel of the instrument.
For details on the connector, refer to Chapter 5.2.2, "AC Power Supply Connec-
tion and Main Power Switch", on page 48.
► Connect the R&S ZNL to the AC power supply using the supplied power
cable.
Since the instrument is assembled in line with the specifications for safety
class EN61010, it must only be connected to an outlet that has a ground con-
tact.
4.1.5 Changing the AC Supply Fuse
If the battery option R&S FPL1-B31 is installed, an AC supply fuse is built into the
AC power supply connector. Only use fuses of the type 5A T IEC60127-2/V (order
no. 0099.6735.00). Such fuses are used for all of the specified nominal AC supply
voltages.
To change the AC supply fuses
1. Disconnect the power cable.
2. Open the flap covering the fuse holder using a small screwdriver (or similar).
3. Remove the fuse holder.
4. Remove the fuse and install the new one.

4.1.6 Connecting an Optional DC Power Supply (R&S FPL1-
B30)
The R&S ZNL can also be equipped with an optional (internal) DC power supply
(R&S FPL1-B30). If installed, the R&S ZNL can be operated by a DC voltage of
10.4 V to 28 V.
Risk of electric shock
Insufficient insulation and exceeding the current limitation of external power
supplies for safety extra-low DC voltage (SELV) can lead to electric shock.
Be sure to meet the requirements for reinforced/double insulation in accord-
ance with DIN/EN/IEC 61010 (UL 3111, CSA C22.2 No. 1010.1) or
DIN/EN/IEC 60950 (UL 1950, CSA C22.2 No. 950). Provide current limita-
tion in accordance with DIN EN 61010-1 Appendix F2.1.
DC Connection
► Connect the DC power supply on the rear panel of the R&S ZNL to the power
source using the supplied power cable.
4.1.7 Connecting an Optional Battery Pack (R&S FPL1-B31)
As an alternative to the fixed AC or DC power supply, the R&S ZNL can be oper-
ated by a battery pack if the option R&S FPL1-B31 is installed. If the battery pack
is installed and neither DC nor AC power is supplied, the R&S ZNL automatically
switches to battery operation (during operation).
The R&S ZNL comes with the battery pack already installed if the battery option
was ordered together with the instrument. Otherwise, insert the battery packs in
the slots at the top of the rear panel.
Putting into Operation

Preparing for Use
R&S®ZNL
19Getting Started 1323.2867.02 ─ 09
The battery pack is charged directly in the R&S ZNL via the common AC or DC
power supply. The battery pack can be charged at an ambient temperature
between +0 °C and +45 °C. If the temperature is above or below these values,
charging is interrupted. If the battery temperature rises above +53 °C, charging is
stopped.
When the battery is being charged in standby mode, the [Power] LED
blinks. During operation, the status bar indicates that the battery is
being charged.
The battery pack is not charged in the factory. The battery pack must be
charged before it is used the first time. A new battery pack or a battery pack
which has not been used for a longer time attains full capacity after several
charge/ discharge cycles.
Charging should be performed at a constant ambient temperature as tem-
perature variations may cause the charger to be switched off too early.
Additional battery packs (R&S FPL1-Z4)
In addition to the internal battery pack option (R&S FPL1-B30), spare battery
packs are available for the R&S ZNL (R&S FPL1-Z4). You can exchange the bat-
teries while the R&S ZNL is running, as long as one battery remains in the instru-
ment. However, it is not recommended that you operate the R&S ZNL with only
one battery for a longer period. Additional battery packs can also be charged
using the external battery charger option R&S FSV-B34.
