Microwave signal generator tackles phase noise

Analogue microwave signal generator is suitable for a variety of telecommunications and radar applications.

With its new analogue R and S SMF100A microwave signal generator, Rohde and Schwarz can handle the issue of single-sideband (SSB) phase noise.

A SSB phase noise value of -115dBc (at 10GHz/10 kHz offset) makes the instrument suitable for a variety of telecommunications and radar applications.

In addition, high output power and very short setting times enable flexible applications in production.

The R and S SMF100A is designed for a frequency range up to 22GHz.

High throughput and good signal quality are key requirements placed on test equipment in a modern production environment.

Rohde and Schwarz is well-known for the short level and frequency setting times of its signal generators.

The new R and S SMF100A microwave signal generator also achieves an outstanding value of 4 and 3 ms for frequency and level respectively.

Setting times of less than 700us can be considerably reduced even further in the list mode.

Moreover, the instrument provides output power of typically +26dBm without an external amplifier, making it easy to compensate for cable loss and transfer impedance.

The signal quality of the R and S SMF100A opens up a variety of applications.

For example, it can be used in two-tone-measurements, or as a local oscillator for phase noise measurements.

Ultra-pure signals are also essential for many applications in telecommunications, for example, to simulate CW interferers.

Adjustable signal quality is an advantage in synthesiser tests.

The R and S SMF100A offers a special feature for this case - FM- or PhiM-modulated noise can be added to the signal in order to artificially correct the SSB phase noise of the signal generator downward by the desired value.

The new microwave signal generator also excels in ease-of-operation.

The settings on the instrument are made via a block diagram.

As a result of this graphical user interface of virtually intuitive menus, operation is very easy.

With its standard equipment, the R and S SMF100A can be controlled via a LAN; other interfaces such as USB or GPIB are available as options.

The removable data memory ensures that all user data is protected against unauthorised access during calibration and repair, and the instrument thus corresponds to the high security standards in the military sector.

The RandS SMF100A is now available from Rohde and Schwarz.
