Diverse high-quality test signals
The generators in the Audio Analyzers R&S UP300 and
R&S UP350 set new standards in the lower price segment. By providing a
wide variety of sinewave signals, two-tone and multitone signals,
bursts and noise, the instruments offer the ideal test signals for
measurements in the lab, in service and in production, as well as in
university education. Because the audio analyzers have inherent
distortion of less than –90 dB, even high-end audio devices can be
measured |
