Rohde & Schwarz Signal Generators Gain WLAN And GPS Simulation Capabilities

Columbia, MD -- Rohde & Schwarz has introduced two software options for its R&S SMx Series RF signal generators that allow the instruments to produce signals compatible with IEEE 802.11a/b/g WLAN standards and simulate up to four GPS satellites per baseband generator.

The two options can be installed in the R&S SMU200A signal generator that is designed for research and development applications, the R&S SMATE200A for production environments, and the R&S SMJ100A, a general-purpose instrument for use in both research and development and production.

The R&S SMx-K48 software option enables the three signal generators to be WLAN compatible. The maximum chip/sample rate is 20 Mc/s for the IEEE 802.11a/g standards using Orthogonal Frequency Division Multiplexing (OFDM) and 11 Mc/s for IEEE 802.11b/g standards using Complimentary Code Keying (CCK) and Packet Binary Convolutional Code (PBCC). The Physical Layer Service Data Unit (PSDU) bit rates can be varied and MAC headers activated.

The second option (R&S SMx-K44) allows development of mobile radio equipment with GPS functionality. It uses current almanac navigation data and PN sequences for bit error rate tests. For each baseband generator installed in the instrument, signals are generated to simulate reception of up to four GPS satellites. The allows the R&S SMJ100A to simulate up to four satellites and the R&S SMU200A and R&S SMATE200A up to eight (when two integrated baseband generators are used).

The R&S SMx-K48 and R&S SMx-K44 software options are available for immediate delivery from Rohde & Schwarz.
