1、 Second Edition January 2008 Audio Analyzers UP 300/UP 350 10 Hz to 80 kHz The new product family from Rohde can also be superimposed on the sinewave signals Audio Analyzers UP 300/UP 35012 5 Diverse high-quality test signals The generators in the Audio Analyzers UP 300 and UP 350 set new stan- dard

2、s 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 uni- versity education. Because the audio analyzers h

3、ave inherent distortion of less than 90 dB, even high-end audio devices can be measured. High-end measurement characteristics The audio analyzers offer bandwidths of up to 80 kHz, enabling the user to perform measurements even on broadband audio equipment. The UP 350 is capable of sampling rates up

4、to 192 kHz unprecedented in this class of instruments. Extensive selection of filters The UP 300 and UP 350 contain a wide variety of weighting, third-octave and octave filters. As many as three filters can be combined. Powerful FFT analysis The FFT analysis capability of the UP 300/350 also sets ne

5、w standards in this class of instruments. This capability supports up to 16 k points and provides numer- ous window functions, which enables it to display the spectral composition of sig- nals up to 80 kHz in bandwidth. 6Audio Analyzers UP 300/UP 350 The new instrument family equipped for the future

6、 Versatile applications Desktop use Portable for mobile use Integration into 19-inch racks 7Audio Analyzers UP 300/UP 350 USB interfaces The USB host interface links the instruments to the PC world. The bus ensures high data transmission rates at low cost. Other peripherals (e.g. printers) can be ad

7、dressed via another USB interface. Identical housing All instruments based on the Family 300 concept have an almost identical “face”, a 5.4-inch TFT display, front- panel control elements, protective guards and a handle that can be adjusted to different positions. Only the connectors on the front an

8、d rear panel vary depending on the instrument type. If the protective guards and the handle are removed, the UP 300/350 can be installed in a 19-inch rack. Owing to their slim design, two instruments of the Family 300 can be placed next to each other. In addition to its analog interfaces, the UP 350

9、 has digital BNC interfaces in consumer and professional format on its rear panel.
