SMBV100A vector signal generator

Wednesday, 29 April, 2009 | Supplied by: Rohde & Schwarz (Australia) Pty Ltd

The SMBV100A vector signal generator from Rohde & Schwarz offers performance that until now has been available only in more expensive instruments.

It provides an output level of typical +24 dBm up to 6 GHz and a maximum RF bandwidth of 528 MHz. Digital standards such as WiMAX, 3GPP FDD, HSPA and LTE can be configured directly on the instrument using its user interface.

An integrated modulation generator generates the baseband signals internally, eliminating the need for a PC.

The instrument is suitable for users who develop digital RF modules, produce RF receivers or investigate highly complex radar applications. Developed to provide maximum options flexibility, it can be adapted to a wide range of requirements and offers maximum functional diversity.

For measurement tasks in research and development, the generator, which features a frequency range from 9 kHz to 6 GHz and an RF bandwidth of up to 120 MHz with internal baseband, has been designed to handle next-generation wireless communications technologies.

Using an external I/Q source, the RF bandwidth can be extended to 528 MHz. Digital radio standards are available at the press of a button.

Due to its short frequency and level setting times (\<1 ms in list mode), the instrument enables high production throughput. The large ARB memory ensures that different test scenarios are simultaneously available.

This makes it possible to directly switch between signals without time-consuming reloading. The resulting fast switchover times also contribute to speeding up production. When a power sensor of the R&S NRP family is connected, the device can determine the test set-up’s cable losses and frequency response. Owing to the high output level of typical +24 dBm, losses are compensated without the external amplifiers that are normally needed in such tests. The long calibration interval of three years and the advantage of being able to perform service on site minimise downtimes of the test system.

The generator can also be configured to address the special requirements of the aerospace and defence sector. The SMBV-K6 option lets users generate complex pulse scenarios. If a broadband external I/Q source such as the AFQ100B is included in the test set-up, signals with an RF bandwidth of 528 MHz can be generated.

Since phase-locked coupling of the RF synthesisers is possible across multiple instruments, testing antennas with phase-coherent signals can also be performed.
