Signal Analyzer with 2 GHz Analysis Bandwidth

RS FSW08 April 2015 - Developers need large bandwidths to analyze wideband signals like those of the new IEEE 802.11ad WLAN standard, 5G next generation mobile communications signals, and radar chirp signals. Rohde & Schwarz is therefore introducing the new R&S FSW-B2000 hardware option to expand the analysis bandwidth of its R&S FSW high end signal and spectrum analyzer to 2 GHz. This test solution enables R&D users to demodulate extremely wideband signals and analyze them in detail.

There is no other instrument on the market that combines such a large analysis bandwidth with a frequency range up to 67 GHz, and it opens up numerous applications. For example, users can measure the EVM values of communications signals or the chirp rate on chirped radar systems.

To analyze a signal with such a large bandwidth, the R&S FSW downconverts it to an intermediate frequency, which is then wideband digitized by an R&S RTO oscilloscope. The R&S FSW equalizes this digital signal and adjusts the sampling rate. The entire signal path including the oscilloscope is calibrated. Users control the easy to operate setup via the analyzer, which also displays measurement results. R&S FSW measurement applications such as vector signal analysis or pulse and transient measurements make it possible to analyze the signal in detail. No other test solution on the market currently enables both spectrum and modulation measurements in the frequency range up to 67 GHz with such a large bandwidth.

The performance features offered by the R&S FSW make the instrument ideal for developers of devices and components complying with IEEE 802.11ad, the latest WLAN standard, enabling the transmission of high data rates over short distances. IEEE 802.11ad signals have a symbol rate of 1.76 Gsample/s in single carrier mode and require 2 GHz of analysis bandwidth for demodulation.

The R&S FSW-B2000 option for the R&S FSW26 to R&S FSW67 high end signal and spectrum analyzers with frequency ranges up to 26.5 / 43.5 / 50 / 67 GHz is now available from Rohde & Schwarz.
