In these safety instructions, the term "product" covers instruments (oscilloscopes),
probes and their accessories.
Lifting and carrying the instrument
Check the data sheet for the maximum weight of the instrument. A single person can
only carry a maximum of 18 kg safely depending on age, gender and physical condi-
tion. If your instrument is heavier than 18 kg, do not move or carry it by yourself.
Use the instrument handles to move or carry the instrument. Do not use the mounted
accessories instead of the handles. Accessories are not designed to carry the weight
of the instrument.
To move the instrument 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.
You can operate the product up to the altitude specified in the data sheet. The lowest
specified altitude for a product of the measurement setup defines the altitude for the
complete setup.
The product is suitable for pollution degree 2 environments where nonconductive con-
tamination can occur. For more information on environmental conditions such as ambi-
ent 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 prod-
uct 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 sta-
bility. 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 prod-
uct, 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 prod-
ucts 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 and grounding
The mains power supply input of the instrument complies with overvoltage category II.
It has to be connected to a fixed installation used to supply energy-consuming equip-

ment such as household appliances and similar loads. Be aware that electrically pow-
ered products have risks, such as electric shock, fire, personal injury or even death.
Take the following measures for your safety:
●Do not use an isolating transformer to connect the instrument to the mains power
supply.
●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-spe-
cific safety requirements. Only insert the plug into an outlet with protective conduc-
tor terminal.
●If a product has an exchangeable fuse, its type and characteristics are indicated
next to the fuse holder. Before changing the fuse, switch off the instrument and dis-
connect it from the power source. How to change the fuse is described in the prod-
uct documentation.
●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 deliv-
ered with the product or that is recommended in the product documentation or a
power supply that conforms to the country-specific regulations.
●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.
Performing measurements
Take the following measures for your safety:
●To ascertain voltage-free state, use an appropriate voltage tester. Any measure-
ment setup including an oscilloscope is not suitable for this purpose.
●The maximum input voltage on channel inputs and the external trigger input must
not exceed the value specified in the data sheet.
●Observe all voltage and current ratings of the instrument, the probes, and the
accessories. Limits and ratings are marked on the products and listed in the data
sheets.
Consider that the rated voltage depends on the frequency. The voltage limitation
curves or values are provided in the data sheet. Do not exceed the maximum mea-
surement voltage from the probe tip to the probe reference lead.
●Never cause any short circuits when measuring sources with high output currents.
●Use only probes and accessories that comply with the measurement category
(CAT) of your measurement task. The measurement category of the products is
defined in the data sheet. If you use other than Rohde & Schwarz accessories,
make sure that they are suitable for the instrument and the measurement task.
●Set the correct attenuation factor on the instrument according to the probe being
used. Otherwise, the measurement results do not reflect the actual voltage level,
and you might misjudge the actual risk.

●When working with high voltages and current probes, observe the additional oper-
ating conditions specified in this safety instructions.
●The probe pins are extremely pointed and can easily penetrate clothes and the
skin. Handle the probe pins with great care. To exchange a probe pin, use tweez-
ers or pliers to avoid injuries. When transporting the accessories, always use the
box supplied with the probe.
●Prevent the probe from receiving mechanical shock. Avoid putting excessive strain
on the probe cable or exposing it to sharp bends. Touching a broken cable during
measurements can cause injuries.
●Set up all probe connections to the instrument before applying power.
Working with hazardous voltages
Voltages higher than 30 V RMS, or 42 V peak, or 60 V DC are regarded as hazardous
contact voltages. Direct contact with them can cause serious injuries.
Make sure that only electrically skilled persons use the products for measurements on
hazardous contact voltages. These working conditions require special education and
experience to perceive risks and to avoid hazards which electricity can create.
When working with hazardous contact voltages, use protective measures to preclude
direct contact with the measurement setup:
●Do not touch exposed connections and components when power is applied.
●Switch off the test circuit while connecting and disconnecting probe leads.
●Use only insulated voltage probes, test leads and adapters.
●Make sure that the input leads fulfill the safety requirements for your measurement.
The delivered input leads might have a jacket wear indicator that indicates a worn
jacket by different jacket color. In this case, do not use the input lead. Replace it
with a new one.
●Do not use 4 mm banana plugs without protection against contact.
Working with current probes
When working with current probes, you can measure high-frequency currents or cur-
rents that contain high-frequency components.
●Switch off the test circuit while connecting the probe.
●Do not attach the clamp to bare unisolated conductors. To avoid injury from a short
circuit, measure at a location on an insulated wire where the insulation is sufficient
for the circuit voltage.
●Connect the probe only to the secondary side of a breaker. With this measure, you
avoid injury, if a short circuit occurs.
●The following effects can cause burns and fire or damage to the measurement site:
– Eddy current loss can cause heating of the sensor head.
– Dielectric heating can cause heating of cord insulation and other materials.
