R&S®SMU200A Vector Signal Generator

The art of signal generation

Features

Outstanding signal quality

Owing to the sophisticated multiloop synthesizer concept, the R&S®SMU200A features extremely low SSB phase noise and wideband noise. A high-stability oven-controlled reference oscillator is installed as standard, which provides excellent aging characteristics as well as minimum temperature drift. The R&S®SMU200A is ideal, for instance, for LO or VCO substitution.

Typical SSB phase noise at 100 MHz, 850 MHz, 2.1 GHz and 5.7 GHz with internal reference oscillator (without low phase noise option)

Amplifiers of 3GPP base stations require very good adjacent channel leakage ratio (ACLR) performance in order not to impair the adjacent channels of the transmission. To test this feature, the ACLR characteristics of the signal generator must be better than those of the amplifier. Presently, multicarrier power amplifiers are increasingly used. In this case, not only one but several neighbouring signals in the frequency range are amplified. Testing such amplifiers places even higher demands on signal generator capabilities. The outstanding ACLR characteristics of the R&S®SMU200A more than qualify the generator for this task.
