The R&S SGS100A, a new signal generator from Rohde & Schwarz, is claimed to enable production lines to work faster and more cost-effectively. It covers the frequency range from DC to 12.75 GHz and has been optimized for use in automated test systems. The signal source is compact so that it fits in one-half the width of a 19 inch rack and requires a single height unit. Its size means that four RF sources can be installed in the space previously needed for one. With typical frequency and level setting times of 280 µs, the R&S SGS100A is said to be three times faster than its conventional counterparts. This means higher production test throughput in addition to significantly reduced space requirements.
The R&S SGS100A offers a very high output level of typically +22 dBm as standard and has an electronic step attenuator covering the entire frequency range. Its low nonharmonics of –76 dBc up to 1.5 GHz make the generator a suitable signal source for converter tests.
The new signal generator is available in two models: The CW version generates frequencies up to 12.75 GHz. It can be used as a local oscillator as well as for interference testing against mobile radio standards. The vector signal generator version with integrated I/Q modulator offers a maximum frequency of 6 GHz and covers the most important frequency bands for digital communications standards. RF signals from multiple R&S SGS100A can optionally be phase-locked to support beamforming applications for the aerospace and defense industry.
Hans-Jörg Strufe, Head of Signal Generator Product Management at Rohde & Schwarz: commented, "A signal generator needs to meet three key requirements, particularly in production. It has to be small, fast and reliable. The R&S SGS100A combines all these qualities and, though small in size, offers a level of RF performance normally only found in high-end equipment.”
