R&S introduces unique 2 GHz analysis bandwidth in FSW high-end signal analyser

Published: 6th March 2015

Rohde & Schwarz is expanding the analysis bandwidth of its FSW high end signal and spectrum analyser to 2 GHz by introducing the new R&S FSW-B2000 hardware option.

Developers need large bandwidths to analyse wideband signals like those of the new IEEE 802.11ad WLAN standard, 5G next generation mobile communications signals, and radar chirp signals. The FSW is the first signal and spectrum analyser offering 2 GHz analysis bandwidth in a user friendly, commercial solution.

This new hardware option enables R&D users to demodulate extremely wideband signals and analyse 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, opening up numerous applications. For example, you can measure the EVM values of communications signals or the chirp rate on chirped radar systems.

To analyse a signal with such a large bandwidth, the FSW downconverts it to an intermediate frequency, which is then wideband digitised by an RTO oscilloscope. The FSW equalises this digital signal and adjusts the sampling rate. The entire signal path including the oscilloscope is calibrated. This easy-to-operate setup is controlled via the analyser, which also displays measurement results. FSW measurement applications such as vector signal analysis or pulse and transient measurements make it possible to analyse 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 FSW is 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.
