14Manual 1179.5660.02 ─ 02
3 Unpacking and checking
1. Unpack the FE170-type external frontend carefully.
2. Retain the original packing material. Use it when transporting or shipping the
FE170-type external frontend later.
3. Using the delivery notes, check the equipment for completeness.
4. Check the equipment for damage.
If the delivery is incomplete or equipment is damaged, contact
Rohde & Schwarz.

Setting up the external frontend

15Manual 1179.5660.02 ─ 02
4 Setting up the external frontend
The FE170-type external frontend is used exclusively in test setups with a control
instrument, e.g. the R&S SMW200A.
To place the FE170-type external frontend on a bench top
1. Place the FE170-type external frontend on a stable, flat and level surface.
2. The top of the FE170-type external frontend is too small for stacking. If you
want to stack the FE170-type external frontend together with other products:
a) Follow the instructions given for the other products.
b) Place the FE170-type external frontend on top.
3. NOTICE! Overheating can damage the product.
Prevent overheating as follows:
● Keep a minimum distance of 10 cm between the fan openings of the
FE170-type external frontend and any object in the vicinity.
● Do not place the FE170-type external frontend next to heat-generating
equipment such as radiators or other products.

Connecting the external frontend

16Manual 1179.5660.02 ─ 02
5 Connecting the external frontend
When connecting the FE170-type external frontend in your test setup, use the
cables provided with the delivery.
5.1 Considerations for test setup
Cable selection and electromagnetic interference (EMI)
Electromagnetic interference (EMI) can affect the measurement results.
To suppress electromagnetic radiation during operation:
●Besides the cables delivered with the FE170-type external frontend, use high-
quality shielded cables for the following connector types:
– SMA and 2.92 mm: RF cables that match this connector type.
How to: Chapter 5.5, "Connecting to SMA and 2.92 mm connectors",
on page 20.
– LAN: at least CAT6+ cables.
How to: Chapter 5.3, "Connecting to LAN", on page 18
●Always terminate open cable ends.
●Ensure that connected external devices comply with EMC regulations.
Signal input and output levels
Information on signal levels is provided in the data sheet. Keep the signal levels
within the specified ranges to avoid damage to the FE170-type external frontend
and connected devices.
Preventing electrostatic discharge (ESD)
Electrostatic discharge is most likely to occur when you connect or disconnect a
DUT.
►NOTICE! Electrostatic discharge can damage the electronic components of
the product and the device under test (DUT).
Ground yourself to prevent electrostatic discharge damage:
a) Use a wrist strap and cord to connect yourself to ground.
Considerations for test setup

Connecting the external frontend
R&S®FE170ST / R&S®FE170SR
17Manual 1179.5660.02 ─ 02
b) Use a conductive floor mat and heel strap combination.
To block DC components
►NOTICE! Excessive DC voltage at the RF input connector can damage the
instrument. Make sure the values are within the DC limits given in the data
sheet.
Insert a DC blocker.
5.2 Connecting to power
Only use the external power supply and the AC power cable delivered with the
FE170-type external frontend.
For safety information, see the instructions delivered with the external power sup-
ply. Required ratings of the DC input level and maximum current are listed next to
the socket and in the data sheet.
1. Connect the DC power cable to the socket of the power supply connector on
the rear panel.
For R&S FE170ST, see Figure 6-3.
For R&S FE170SR, see Figure 6-4.
2. Connect the other end of the DC power cable to the external power supply.
3. Insert the AC power plug into a power outlet with ground contact.
If connected to power, the FE170-type external frontend switches on automati-
cally. On the front panel of the FE170-type external frontend, the "Power" LED
switches from gray to green, see Table 5-1.
To troubleshoot hardware problems
Both a red "Power" LED and red "LAN" LED indicate hardware problems that
result in a malfunction of the FE170-type external frontend. If hardware problems
occur, the FE170-type external frontend switches to a safe state. The LAN con-
nection is aborted.
If the "Power" LED or the "LAN" LED or both are red, proceed as follows:
1. Switch off the FE170-type external frontend.
No disconnection of the cabling is required.

5.3 Connecting to LAN
To connect to LAN
► Connect the LAN socket on the rear panel via an RJ-45 cable to the LAN.
If connected, the "LAN" LED is green, see Table 5-2.
IP address assignment
The IP address is assigned automatically by one of the following methods:
●By default, the FE170-type external frontend is configured to use DHCP
(dynamic host configuration protocol) and no static IP address is configured. If
switched on and connected to the LAN, the FE170-type external frontend dis-
Connecting to LAN

Connecting the external frontend
R&S®FE170ST / R&S®FE170SR
19Manual 1179.5660.02 ─ 02
plays the IP address information on the electronic label with "IP Addr.:". See
Chapter 6.3, "Electronic label", on page 32.
●If the network does not support DHCP or the attempt does not succeed, the
external frontend tries to obtain the IP address via Zeroconf (APIPA) protocol.
IP addresses assigned via Zeroconf start with the number blocks 169.254.*.*.
Note: An IP address that is assigned via the Zeroconf protocol although the
network requires an IP address assigned via the DHCP server can cause net-
work connection failures.
You can also assign the IP address of the FE170-type external frontend manually
on the control instrument.
See "Frontend control documentation" on page 12.
To reset the IP address
If, e.g. a manually assigned IP address of the FE170-type external frontend is
located in another subnet than the IP address of the control instrument, you can
reset the IP address of the FE170-type external frontend .
Prerequisites: The frontend is switched on and connected to LAN.
► Press the "IP Preset" button on the rear panel of the FE170-type external fron-
tend using a pointed tool for about 1 second.
After resetting, the FE170-type external frontend reboots.
5.4 Connecting to the waveguide connector
The "RF Out" (R&S FE170ST) or "RF In" (R&S FE170SR) connector is a WR-6.5
waveguide connector.
The precision waveguide flange of the WR-6.5 waveguide connector provides two
pins and two holes for aligning the DUT.
1. Remove the protective cap from the waveguide connector on the front panel.
2. Inspect the waveguide flange connector visually to check that it is clean,
undamaged and mechanically compatible.
Thus, you prevent insertion loss and mismatch, and even premature wear of
the connectors.

3. Carefully align the pins to the holes of the WR-6.5 waveguide connectors on
the DUT to the holes of the connector on the FE170-type external frontend
until they match.

2, 4 = Hole for pin of the DUT
4. Carefully put the WR-6.5 waveguide connectors of the DUT and the FE170-
type external frontend together.
5. NOTICE! Excessive tightening can damage the connectors.
Screw the WR-6.5 waveguide connectors together:
a) Align the screw of the WR-6.5 waveguide connector to the screw thread of
the opposite connector.
b) Use a calibrated torque wrench to torque the screw to 0.58 Nm, e.g.
R&S ZCTW (order no. 1175.2014.02).
5.5 Connecting to SMA and 2.92 mm connectors
The "Ref In" connector and the "LO In"/"LO Out" connectors are SMA female con-
nectors. The "IF In" (R&S FE170ST) and "IF out" (R&S FE170SR) connector is a
2.92 mm connector.
For information on how to handle and maintain the screwable connectors, to
minimize measurement deviations and ensure its longevity, see application
note 1MA99.
1. Inspect the connector visually to check that it is clean, undamaged and
mechanically compatible.
Thus, you prevent insertion loss and mismatch, and even premature wear of
the connectors.
