R&S®SMB100B with connected R&S®NRP power sensor (via USB).

Perfect for signal quality

Very low SSB phase noise of < –134 dBc (meas.) at 1 GHz and an offset of 20 kHz

In order to improve a DUT, the signal quality of the signal source has to be significantly better than the DUT’s performance. Thanks to its innovative synthesizer design, the R&S®SMB100B has very low SSB phase and wideband noise and excellent suppression of nonharmonic signal components.

Perfect for use

The user friendliness of the R&S®SMB100B is evident in many ways

The RF signal generator is simple to operate, supports working with a connected R&S®NRP power sensor and can emulate legacy instruments. In addition one can create its own "user menu".

From left to right:
1. The graphical user interface with high-resolution touchscreen makes the R&S®SMB100B very easy to use. The main screen clearly displays all important parameters and information to save the user time when looking for functions.
2. Individual menu items can be added to the user menu. Added items are marked with a blue star.
3. Example of a user menu. The individually composed parameters can be directly set in this menu.

Variable reference frequency inputs/outputs

The R&S®SMB100B provides various ways to output (or input) reference signals. The 1 MHz to 100 MHz variable external reference frequency input (R&S®SMBB-K704 option) allows the R&S®SMB100B to be easily integrated into existing test environments. The received reference frequency can also be output to a separate reference output (for details please refer to the data sheet). Extremely good phase stability between multiple R&S®SMB100B instruments can be achieved with the optional 1 GHz reference frequency input and output (R&S®SMBB-B3 option).

Refresh your T&M equipment

When individual pieces of equipment become obsolete before the entire ATE system does, regular calibration and repair of obsolete equipment is an expensive, timeconsuming and challenging task. Replacing obsolete test equipment with equivalent state-of-the-art instruments should be straightforward and require minimal hardware and software changes. The R&S®LegacyPro code emulation fulfills these requirements, reducing the workload and eliminating risks.

R&S®NRP power sensor connectivity

An R&S®NRP power sensor can be connected to the R&S®SMB100B

A DUT is rarely connected directly to the generator. There are often cables and other components between the generator and the DUT. This shifts the reference plane from the generator’s RF output to the DUT. An R&S®NRP power sensor can be connected to the R&S®SMB100B to allow extremely precise calibration (tenth of a dB) at this new reference plane.

UCOR (user correction)

Compensation of an external frequency response by the R&S®SMB100B with a connected R&S®NRP power sensor

DUTs are often connected to the signal generator via long cables or other frequency-dependent components. It is therefore very important to compensate the frequency response. The R&S®SMB100B provides a user correction (UCOR) function for this purpose. Together with R&S®NRP power sensor the UCOR values are automatically determined by a push of a button. With UCOR, a frequency response compensated RF signal is available at the new reference plane.
