Rohde & Schwarz's two new options for its R&S SMF100A microwave signal generator expand its capabilities significantly. The R&S SMF-K27 option facilitates radar-specific developments and tests and the R&S SMF-K28 option makes the R&S SMF100A the first signal generator worldwide to handle power analysis.

The R&S SMF-K27 option allows users to generate pulse trains with very short rise and fall times. It makes use of the full dynamic range and speed of the pulse generator and modulator that can be integrated as options into the R&S SMF100A. This pulse train generation concept is unique, according to the company.

Microwave signal generators are standard tools for developers of amplifiers and other components. When developers want to measure the signal power on DUTs, however, they usually have to rely on a power meter or spectrum analyzer.

The R&S SMF-K28 option offers the unique alternative of performing power analyses such as compression point measurements using an R&S SMF100A microwave signal generator. The results can be read, stored and displayed. In addition, the power vs. frequency value can be measured to test the frequency response of a filter, for example.

The R&S SMF100A microwave signal generator outputs the measured frequency response on its display. Furthermore, it offers insertable markers for indicating which power is determined at a specific frequency.

To take advantage of these functions, a power sensor of the R&S NRP-Z family simply needs to be connected to the microwave signal generator. An external PC is not necessary.

To benefit from the pulse-train option, the R&S SMF100A must be equipped with the R&S SMF-K3 (pulse modulator) and the R&S SMF-K23 (pulse generator) options.

The R&S SMF-K27 option for pulse trains and the R&S SMF-K28 option for power analysis are now available from Rohde & Schwarz Inc. priced at $2,110 each.
