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 sig-
nals 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 Wi-
Fi and ISM applications (industrial, scientific and medical). These tests are per-
formed 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 elec-
tronic 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).
