Preface
1 Preface
The R&S OSP-B157W8 or R&S OSP-B157W8PLUS and R&S OSP-B157WX are
standard modules for the open switch platform R&S OSP.
The R&S OSP-B157WX serves as a frequency extension for the base module
R&S OSP-B157W8 or R&S OSP-B157W8PLUS. While the extension forwards
lower frequency signals to the base module, it can bypass higher frequency signals to an appropriate measurement channel.
Both modules are typically used in the automatic test system R&S TS8997 that
performs regulatory conformance tests of wireless short range devices (SRDs).
The tests cases are focused on the 2.4 GHz and 5 GHz frequency bands for WiFi and ISM applications (industrial, scientific and medical). These tests are performed according to the standards FCC 15.407, ETSI EN 300 328,
ETSI EN 301 893, ETSI EN 302 502, ETSI EN 300 440 and others.
Intended use
The R&S OSP-B157W8, R&S OSP-B157W8PLUS and R&S OSP-B157WX
are designated for the development, production and verification of electronic components and devices in industrial and laboratory environments.
Use the modules only for their designated purpose. Observe the operating
conditions and performance limits stated in the data sheets.
Designation "module" vs. "switch unit"
This manual uses the following nomenclature:
●
The R&S OSP-B157W8 is referred to as "base module".
●
The R&S OSP-B157W8PLUS is referred to as "base module".
●
The R&S OSP-B157WX is referred to as "extension module".
●
The R&S OSP is referred to as "switch unit".
Integration
●
The base module R&S OSP-B157W8 or R&S OSP-B157W8PLUS is (or must
be) integrated in an R&S OSP150 or R&S OSP120 switch unit.
●
The extension module R&S OSP-B157WX is (or must be) integrated in an
R&S OSP120 switch unit (not in an R&S OSP150).

Preface
Except for one optional additional single-slot module in slot A11 of the switch unit,
no additional modules can be installed in a single switch unit beside one
R&S OSP-B157W8, one R&S OSP-B157W8PLUS or one R&S OSP-B157WX.
For all information related to the R&S OSP switch units, refer to their operating
manual.
Frequency ranges
Basically, the modules are designed to cover the 2.4 GHz and 5 GHz frequency
bands. However, some of the above mentioned regulatory ETSI and FCC tests
include measuring spurious emissions up to 18 GHz or even up to 40 GHz.
Therefore, the frequency coverage of the modules is as follows:
●
The R&S OSP-B157W8 operates in a frequency range up to 6 GHz. The
R&S OSP-B157W8PLUS operates in a frequency range up to 7.5 GHz. Both
base modules offer a special by-path for spurious emissions measurements
up to 18 GHz. The integrated power meter and signal conditioning is designed
for in-band use only.
The lower end of the frequency range of the R&S OSP-B157W8 and
R&S OSP-B157W8PLUS depends on the selected paths and application. It
starts, for example, approximately at 100 MHz, if internal power measurements are involved, or approximately at 1 GHz, if directional couplers are
involved.
●
The R&S OSP-B157WX extends the spurious emissions frequency range up
to 40 GHz. Signals to be measured in this frequency range are not forwarded
to the DUT input ports of the base module, but bypassed directly to the signal
analyzer.
Key features of the base module R&S OSP-B157W8
The 6 GHz module R&S OSP-B157W8 with up to 8 channels is based on a printed RF switch board in solid-state relay (SSR) architecture. It allows flexible operation of the connected DUT (up to 8 ports) and measurement instruments.
The module features:
●
Signal conditioning by integrated attenuators, couplers and combiners (without amplifiers or filters)
●
RF switching for wireless test cases up to 6 GHz
●
RF switching for spurious emission measurements up to 18 GHz (exception: if
a frequency extension module R&S OSP-B157WX is present, these signals
are handled within the extension module)

Key features of the base module R&S OSP-B157W8PLUS
In addition to the features of the ".02" version R&S OSP-B157W8, the ".05" version of the module features:
●
Frequency range for signalling up to 7.5 GHz
●
Additional step attenuator R2 for an extended attenuation range, see Fig-
ure 4-3
Each of the 8 configurable channels in the R&S OSP-B157W8 and R&S OSPB157W8PLUS has the following integrated semiconductor components:
●
An individually programmable attenuator
●
An analog power detector for synchronous RMS power measurement with
high sampling rate and burst detection
●
An A/D converter for the power measurement results
●
Solid-state switches, which enable:
– Switching the (vector) signal generator output to the calibration port or to
the DUT ports
– Switching the measurement paths from DUT ports to a spectrum analyzer /
test receiver or to the power measurement
– Signal conditioning via the integrated couplers, directional couplers,
attenuators and combiners
Key features of the frequency extension module R&S OSP-B157WX
The 40 GHz module R&S OSP-B157WX is especially designed to provide RF
switching for spurious measurements up to 40 GHz.

R&S®OSP‑B157WX
Preface
It uses coaxial RF architecture and features:
●
Electromechanical RF relay switches for flexible operation of up to 8 DUT
channels
●
The module can forward incoming signals on each DUT channel to the connected DUT input of the R&S OSP-B157W8 or R&S OSP-B157W8PLUS. This
forwarding is used for measurements at frequencies up to 6 GHz, which the
R&S OSP-B157W8 can handle, or up to 7.5 GHz, which the R&S OSPB157W8PLUS can handle.
●
Alternatively, incoming signals on one single DUT channel can be switched to
the module's [Rx] port and on to a connected signal analyzer, receiver or other
measurement instrument. This switching state is typically used for measurements at frequencies above 6 GHz or 7.5 GHz and up to 40 GHz, which the
base modules cannot handle. (Signals for spurious emission measurements
up to 18 GHz are also switched to the instrument connected to the extension
module's [Rx] port.)
●
If the R&S OSP-B157WX forwards the DUT's signals, it also switches the signal analyzer path from its [RxOUT] port (input port) to its [Rx] port. This [Rx]
port is connected to the signal analyzer or test receiver, while the [Rx] port of
the R&S OSP-B157W8 or R&S OSP-B157W8PLUS is connected to the
[RxOUT] port (input port) of the R&S OSP-B157WX.
●
Additionally, you can add the signal of a companion device to one of the DUT
paths via its internal switches and a directional coupler. The type of companion device depends on the DUT. For example, if your DUT is a Wi-Fi transceiver, the companion device can be a wideband radiocommunication tester
R&S CMW500. In this example, it would simulate a wireless router that maintains a bidirectional connection with the transceiver.

3.1 Unpacking and Checking
If your delivery includes a module that is not mounted in a switch unit, be especially careful with unpacking the module, which is not protected in a casing.
Check the delivery for completeness according to the included shipment list. If the
delivery is incomplete, contact Rohde & Schwarz.
Retain the original packing material. If the instrument needs to be transported or
shipped later, you can use the material to protect the control elements and connectors.
Mounting modules into switch units
●
If you have received one or more modules that are already integrated in
switch units, you can skip the chapters Mounting the Base Module and Mount-
ing the Extension Module. Proceed with Chapter 3.5, "Putting into Operation",
on page 25.
●
If you have received one or more modules that are not yet integrated in
switch units, proceed with chapters Mounting the Base Module and Mounting
the Extension Module.
3.2 Mounting the Base Module
Mounting the base module R&S OSP-B157W8 or R&S OSP-B157W8PLUS into
an R&S OSP150 or R&S OSP120 switch unit requires the space of two slots: rear
slots A12 and A13 together with front slots A12F and A13F. Typically, the rear slot
A11 remains free, but optionally it can remain occupied by a single-slot module
