Connecting to RF
4.9 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 the values do not exceed the reverse power and DC limits as
given in the data sheet.
3. If the R&S SMBV100B 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 22.

Connecting to LO In/Out
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.
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.
See "RF" on page 39.
To prevent RF output switch-off
► NOTICE! If you set a too high output level without a load connected to the
instrument, the reverse power can exceed a limit forcing the R&S SMBV100B
to switch off the RF output.
Preparing for use
Connect a load with sufficient return loss as given in the data sheet.
4.10 Connecting to LO In/Out
"LO In/Out" connectors are Subminiature Version A (SMA) connectors.
The connector is located on the rear panel.
1. Use a high-quality cable that matches the connector type.
See "Cable selection and electromagnetic interference (EMI)" on page 22.
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.
