Professional audio analyzer
for production, laboratory and service
The ¸UP 300 and ¸UP 350 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 ¸UP 300

Applications
Because of its large scope of functions, the
¸UP 300 is ideal for numerous analog audio
applications. The ¸UP 350 is even more powerful, with the added capability of performing
measurements on digital audio instruments.

¸UP 300/¸UP 350
Diverse high-quality test signals
The generators in the Audio Analyzers ¸UP 300 and ¸UP 350 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.
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 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 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 TFT display, frontpanel 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.

In addition to its analog interfaces, the ¸UP 350 has digital BNC interfaces in consumer and professional
format on its rear panel.
