Rohde & Schwarz, a manufacturer of equipment for mobile radios and radiocommunications, has released the SMW200A vector signal generator for “generating complex, digitally modulated signals of high quality.” The generator covers a frequency range from 100 kHz to 3GHz and also “features an I/Q modulation bandwidth of 160 MHz with internal baseband.”
Allowing for maximum flexibility, the SMW200A can has an optional second RF path for frequencies up to 6GHz “with a maximum of two baseband and four fading simulator modules,” essentially putting two signal generators in one. Several options are available for digital communications, all running from the product without having to connect to external computer. For extra user-friendliness, the SMW200A has a new touchscreen that “allows users to control the instrument even more intuitively.”
R&S say that the SMW200A has excellent signal quality which “ensures high accuracy in spectral and modulation measurements. The SSB phase noise is –139 dBc (typ.) at 1 GHz (20 kHz offset). In terms of modulation quality, the R&S SMW200A scores top marks with an EVM of –49 dB (meas.) for WLAN IEEE 802.11ac signals as well as a 0.05 dB (meas.) I/Q modulation frequency response over 160 MHz bandwidth.”
