Rohde & Schwarz SMV03 Vector Signal Generator

The Vector Signal Generator R&S® SMV03 is based on the successful analog Signal Generator R&S® SML03 and features the same excellent technical characteristics. It comprises an additional broadband I/Q modulator that is able to generate any digital signal in conjunction with an external I/Q source. The R&SŪ SMV03 is, therefore, a way of entering the wide field of automatic test systems as well as gaining access to applications such as R&D and service. When used together with the R&S® AMIQ and R&S® WinIQSIM™, the R&S® SMV03 can generate digital signals that meet any requirement.

Versatility

The SMV03 generates all kinds of I/Q-modulated signals using the integrated vector modulator. Owing to its wide I/Q bandwidth of 50 MHz, the SMV03 is also optimally suited for applications using high data rates such as WLAN standards. Signals to digital standards can be easily generated in conjunction with an external I/Q source like the Modulation Generator AMIQ (PD 0757.3970) and the associated WinIQSIM™ simulation software.

Speed

Speed is essential - especially in production. And this is exactly where the SMV03 shows what it can do with a frequency and level setting time of <10 ms.

Example: Component Test

Tests using digital signals are becoming increasingly important for checking the functions of individual components - especially at the component production stage. In this environment, the R&SŪ SMV03's I/Q modulator shows what it can do. Owing to its wide signal bandwidth of 50 MHz, it can generate a great variety of digital signals when an external I/Q source is used.

To obtain reliable information on component quality, high level accuracy and high output level repeatability are essential. The R&S® SMV03 fully meets these requirements owing to a maximum level uncertainty of <0.5 dB (at levels >-120 dBm) and high reproducibility.

Extremely short frequency and level setting times (<10 ms) allow fast measurements and make the R&S® SMV03 the ideal generator for production testing. Overshoots that occur when the level is changed may damage or even destroy the DUT. This cannot happen with the R&S® SMV03 as no overshoots are produced.
