1 Safety and Regulatory Information
The product documentation helps you use the product safely and efficiently. Follow the
instructions provided here and in the following chapters.
Intended use
The product is intended for the development, production and verification of electronic
components and devices in industrial, administrative, and laboratory environments.
Use the product only for its designated purpose. Observe the operating conditions and
performance limits stated in the data sheet.
Where do I find safety information?
Safety information is part of the product documentation. It warns you of potential dangers and gives instructions on how to prevent personal injury or damage caused by
dangerous situations. Safety information is provided as follows:
●
In Chapter 1.1, "Safety Instructions", on page 19. The same information is provided in many languages as printed "Safety Instructions". The printed "Safety
Instructions" are delivered with the product.
●
Throughout the documentation, safety instructions are provided when you need to
take care during setup or operation.
1.1 Safety Instructions

to the highest technical standards. To use the products safely, follow the instructions
provided here and in the product documentation. Keep the product documentation
nearby and offer it to other users.
Use the product only for its intended use and within its performance limits. Intended
use and limits are described in the product documentation such as the data sheet,
manuals and the printed "Safety Instructions". If you are unsure about the appropriate
use, contact Rohde & Schwarz customer service.

Safety Instructions
move or carry the product. Do not lift by the accessories mounted on the product.
Accessories are not designed to carry the weight of the product.
To move the product safely, you can use lifting or transporting equipment such as lift
trucks and forklifts. Follow the instructions provided by the equipment manufacturer.
Choosing the operating site
Only use the product indoors. The product casing is not waterproof. Water that enters
can electrically connect the casing with live parts, which can lead to electric shock,
serious personal injury or death if you touch the casing. If Rohde & Schwarz provides
accessories designed for your product, e.g. a carrying bag, you can use the product
outdoors.
Unless otherwise specified, you can operate the product up to an altitude of 2000 m
above sea level. The product is suitable for pollution degree 2 environments where
nonconductive contamination can occur. For more information on environmental conditions such as ambient temperature and humidity, see the data sheet.
Setting up the product
Always place the product on a stable, flat and level surface with the bottom of the product facing down. If the product is designed for different positions, secure the product so
that it cannot fall over.
If the product has foldable feet, always fold the feet completely in or out to ensure stability. The feet can collapse if they are not folded out completely or if the product is
moved without lifting it. The foldable feet are designed to carry the weight of the product, but not an extra load.
If stacking is possible, keep in mind that a stack of products can fall over and cause
injury.
If you mount products in a rack, ensure that the rack has sufficient load capacity and
stability. Observe the specifications of the rack manufacturer. Always install the products from the bottom shelf to the top shelf so that the rack stands securely. Secure the
product so that it cannot fall off the rack.
Connecting to power
The product is an overvoltage category II product. Connect the product to a fixed
installation used to supply energy-consuming equipment such as household appliances and similar loads. Keep in mind that electrically powered products have risks, such
as electric shock, fire, personal injury or even death.
Take the following measures for your safety:
●
Before switching on the product, ensure that the voltage and frequency indicated
on the product match the available power source. If the power adapter does not
adjust automatically, set the correct value and check the rating of the fuse.
●
Only use the power cable delivered with the product. It complies with country-specific safety requirements. Only insert the plug into an outlet with protective conductor terminal.
20User Manual 1175.7068.02 ─ 13
R&S®ESR
Safety and Regulatory Information
Safety Instructions
●
Only use intact cables and route them carefully so that they cannot be damaged.
Check the power cables regularly to ensure that they are undamaged. Also ensure
that nobody can trip over loose cables.
●
If the product needs an external power supply, use the power supply that is delivered with the product or that is recommended in the product documentation or a
power supply that conforms to the country-specific regulations.
●
Only connect the product to a power source with a fuse protection of maximum
20 A.
●
Ensure that you can disconnect the product from the power source at any time.
Pull the power plug to disconnect the product. The power plug must be easily
accessible. If the product is integrated into a system that does not meet these
requirements, provide an easily accessible circuit breaker at the system level.
Connecting headphones
Take the following measures to prevent hearing damage. Before using headphones,
check the volume and reduce it if necessary. If you monitor varying signal levels, take
off the headphones and wait until the signal has settled. Then adjust the volume.
Cleaning the product
Use a dry, lint-free cloth to clean the product. When cleaning, keep in mind that the
casing is not waterproof. Do not use liquid cleaning agents.
Meaning of safety labels
Safety labels on the product warn against potential hazards.
Potential hazard
Read the product documentation to avoid personal injury or product damage.
Heavy product
Be careful when lifting, moving or carrying the product. Carrying the product requires a suffi-
cient number of persons or transport equipment.
Electrical hazard
Indicates live parts. Risk of electric shock, fire, personal injury or even death.
Hot surface
Do not touch. Risk of skin burns. Risk of fire.
Protective conductor terminal
Connect this terminal to a grounded external conductor or to protective ground. This connec-
tion protects you against electric shock if an electric problem occurs.

4.1.1 Touchscreen Display
The touchscreen on the front panel of the R&S ESR displays the measurement results.
Additionally, the screen display provides status and setting information and allows you
to switch between various measurement tasks. The screen is touch-sensitive, offering
an alternative means of user interaction for quick and easy handling of the instrument.
Figure 4-2: Touchscreen elements
1 = Toolbar with standard application functions, e.g. print, save/open file etc.
2 = Tabs for individual measurement tasks
3 = Channel information bar for current measurement settings
4 = Diagram header with diagram-specific (trace) information
5 = Measurement results area
6 = Diagram footer with diagram-specific information, depending on measurement mode
7 = Error indicator
8 = Error message, if available
9 = Device status
10 = Progress bar for measurement
11 = Date and time display
12 = Softkeys for menu access
A touchscreen is a screen that is touch-sensitive, i.e. it reacts in a specified way when
a particular element on the screen is tapped by a finger or a pointing device, for example. Any user interface elements that can be clicked on by a mouse pointer can also be
tapped on the screen to trigger the same behavior, and vice versa.
Using the touchscreen, the following tasks (among others) can be performed by the tap
of your finger:
●
Changing a setting

FREQ (CHANNEL) Provides functionality to define frequency parameters, for example:
SPAN Provides functionality to configure the frequency span.
AMPT (SCALE) Provides functionality to configure amplitude or level characteristics, for example:
AUTO SET Provides functionality to automatically define various parameters like the level or
BW Provides functionality to define the resolution and video bandwidth.
SWEEP Provides functionality to configure the sweep, for example:
●
the center or receiver frequency
●
the frequency offset
(CHANNEL is for special applications)
In the realtime application, the span is coupled to the RBW and restricted to
40 MHz.
●
the reference level
●
the attenuation
●
the input impedance
●

●
the number of measurement points
●
the measurement mode (single or continuous measurements)
In the realtime application, the number of measurement points is a fix value (801
points).
