Rohde & Schwarz has announced the availability of the R&S SMC100A with price/performance for the economy segment. Although it is the smallest instrument in its class, the R&S SMC100A still generates signals of extremely high spectral purity. The device integrates AM/FM/fM and pulse modulation. This combination of price and performance makes the R&S SMC100A suitable for service applications, field use and university labs. In addition, its short frequency- and level-setting times of <5 ms ensure efficiency in production applications. The R&S SMC100A is available from 9kHz to 1.1 GHz or 3.2 GHz. The frequency range up to max. 3.2 GHz covers applications in the 2.54 GHz ISM band as well as EMC requirements.

The compact signal generator (1/2 x 19", 2 HU) has excellent values for single-sideband phase noise (typ. –111 dBc, f = 1 GHz, 20kHz offset, 1 Hz measurement bandwidth) and broadband noise (typ. –148 dBc), claims the company.

The high output power of typically greater than +17 dBm allows measurements on DUTs that require a high input level. Attenuation caused by external components such as cables, filters or matching networks can be easily compensated. In many cases, this eliminates the need for external amplifiers.

The R&S SMC100A achieves <0.9 dB level accuracy and <5 ms frequency- and level-setting times.

Rohde & Schwarz is also providing a service concept that includes a long calibration interval of three years, a built-in self-test for simplified error diagnostics, and the availability of precalibrated replacement modules that allow users to perform repairs themselves on-site.
