Rohde & Schwarz, Munich, Germany, has expanded the capabilities of the R&S SMF100A microwave signal generator with the addition of two new options. First, the SMF-K27 option allows users to configure pulse trains for radar-specific developments and tests. The second option, SMF-K28, makes the R&S SMF100A the first signal generator to handle power analysis.

Pulse trains consist of pulses with different durations. Their pulse width and pulse pause can be user-configured. Such signals are frequently used in radar systems to improve performance. Interfering with these pulses is more difficult than with single-pulse signaling. These pulses also enable radar receivers to detect incorrect measurements more easily and prevent receivers from being "blind".

The 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 SMF100A.

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 may have to rely on a power meter or spectrum analyzer. The SMF-K28 option offers the alternative of performing power analyses such as compression point measurements using the SMF100A microwave signal generator. The results can be read, stored, and also displayed as a diagram. In addition, the power-versus-frequency value can be measured to test the frequency response of a filter. 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. A power sensor needs to be connected to the microwave signal generator to take advantage of these functions. An external PC is not necessary.
