Caracteristicas
The R&S UP300 and R&S UP350 are favorably priced audio analyzers with a frequency range up to 80 kHz that can handle any of today‘s common applications.
The instruments feature a broad scope of functions, good technical characteristics and compact design. The R&S UP300 includes all conventional audio engineering measurements and generates the required test signals. Its analog inputs and outputs are dual-channel in design.
The R&S UP350 goes one step further by providing digital audio interfaces and the capability to measure the digital audio protocol and digital sampling rate.
These two audio analyzers offer an immense range of applications - whether on the lab bench, in service or as a flexible measuring instrument in automatic production systems.
Applications
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.
Extensive selection of filters
The R&S UP300 and R&S UP350 contain a wide variety of weighting, third-octave and octave filters. As many as three filters can be combined.
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 such as DVD players. The R&S UP350 is capable of sampling rates up to 192 kHz – unprecedented in this class of instruments.
Powerful FFT analysis
The FFT analysis capability of the R&S UP300/350 also sets new standards in this class of instruments. This capability supports up to 16 k points and provides numerous window functions, which enables it to display the spectral composition of signals up to 80 kHz in bandwidth.

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