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.
Safety and regulatory information
Safety instructions
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.

R&S®SMM100A
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.
Safety and regulatory information
Safety instructions
●
Only use the power cable delivered with the product. It complies with countryspecific safety requirements. Only insert the plug into an outlet with protective
conductor terminal.
●
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.
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.

more than three products on top of each other. Instead, mount them in a rack.
Stack as follows:
● If the products have foldable feet, fold them in completely.
● It is best if all products have the same dimensions (width and length). If the
products have different dimensions, stack according to size and place the
smallest product on top.
● Do not exceed the permissible total load placed on the product at the bot-
tom of the stack:
– 50 kg when stacking products of identical dimensions (left figure).
– 25 kg when stacking smaller products on top (middle figure).
Left = Stacked correctly, same dimensions
Middle = Stacked correctly, different dimensions
Right = Stacked incorrectly, too many products
4. NOTICE! Overheating can damage the product.
Prevent overheating as follows:
● Keep a minimum distance of 10 cm between the fan openings of the prod-
uct and any object in the vicinity.
● Do not place the product next to heat-generating equipment such as radia-
tors or other products.

See chapter "Using Power Sensors" in the user manual.
3.9 Connecting to RF
The connector is located on the front panel.
If you have the instrument equipped with an option for rear panel connectors, the
RF output connector is on the rear panel.
To prepare for connecting to RF
1. NOTICE! Damaged or not clean connections can lead to RF insertion loss
and mismatch, and even premature wear of the connectors.
Before connecting to the port, inspect the RF connector visually to check that
it is clean, undamaged and mechanically compatible.
See the application note 1MA99 for information on how to handle and maintain the RF port, to minimize measurement deviations and ensure its longevity.
2. NOTICE! Risk of instrument damage. Excessive reverse power or DC voltage
at the RF connector can damage the instrument.
Make sure that signal power and DC limits as given in the data sheet.
3. If the R&S SMM100A is switched on, deactivate the RF output, before connecting an RF cable to the RF connector.

In the block diagram, select the block "RF" > "RF Level" > "RF ON > Off".
4. Use a high-quality RF cable that matches the RF connector type.
See "Cable selection and electromagnetic interference (EMI)" on page 17.
To connect to non-screwable connectors (BNC)
► To connect the RF cable with the RF connector, proceed as follows:
a) Carefully align the connector of the cable and the RF connector along a
common axis.
b) Mate the connectors along the common axis until the male pin of the con-
nector of the cable engages with the female socket of the RF connector.
To connect to screwable connectors
1. Use a high-quality cable that matches the connector type.
See "Cable selection and electromagnetic interference (EMI)" on page 17.
Preparing for use
Connecting to RF
2. NOTICE! Risk of instrument damage and connector damage. Excessive tightening can damage the cables and the connectors. However, if you do not
tighten the connectors enough, the measurement results can be inaccurate.
To connect the cable with the connector, proceed as follows:
a) Carefully align the connector of the cable and the connector along a com-
mon axis.
b) Mate the connectors along the common axis until the male pin of the inner
connector engages with the female socket of the outer connector.
c) Turn the nut of the outer connector until the connectors are firmly coupled.
d) Torque the nut to the specified limit using a calibrated torque wrench. Hold
the opposite connector part stationary with a spanner.
For torque limits of the most relevant connector types, see Table 3-1.
For more information, see chapter "Handling" of the application note 1MA99.
If your instrument is equipped with a test port adapter, see the application note
1MA100.
The connector types listed in this table represent the common connectors provided by Rohde & Schwarz. It is considered as general information and therefore
can contain connector types that do not apply to your instrument.
