Rohde & Schwarz Presents the Smallest Fully Integrated Signal Generator for Automated Test Systems


The R&S®SGS100A, a new signal generator from Rohde & Schwarz, enables production lines to work faster and more cost-effectively. Although much more compact than previous RF sources, it delivers the same performance as high-end conventional instruments.

The new R&S®SGS100A signal generator from Rohde & Schwarz covers the frequency range up to 12.75 GHz and has been optimized for use in automated test systems. The signal source is exceptionally compact. It fits in just one-half the width of a 19" rack and requires a single height unit. Its small size means that four RF sources can be installed in the space previously needed for one RF source. With typical frequency and level setting times of 280 ┬Ás, the R&S®SGS100A is three times faster than its conventional counterparts. This means higher production test throughput in addition to significantly reduced space requirements.

The compact R&S®SGS100A provides RF performance comparable with that of high-end signal generators. It offers a very high output level of typ. +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 the ideal signal source for converter tests.

The R&S®SGS100A 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.

The R&S®SGS100A also reduces operating and capital expenditures: Its initial costs are significantly lower than of comparable equipment. In addition, it consumes less power (just 70 W) and dissipates less heat. Besides greater cost-efficiency, this also translates into higher reliability. The calibration interval of three years helps to keep the total cost of ownership down.
