The R&S UPL06 (and UPL66) Audio Analyzer performs practically all types of analog measurements, from frequency response to externally controlled sweeps with reference traces, determination of 3rd-order difference frequency distortion, spectral display of demodulated wow and flutter signals, etc. In contrast to many other analyzers the UPL06 is capable of performing real dual channel measurements in the audio frequency range, i.e., there is no need for switchover between two inputs.
The Rohde & Schwarz UPL06 and UPL66 models feature excellent specifications: analgo sinewave generation with harmonics of typical -115 dB, spectrum displays with a noise floor below -140 dB for analog and -160 dB for digital interfaces, FFT with a maximum frequency resolution of 0.05 Hz, etc.
The R&S UPL06 Audio Analyzer offers a large selection of functions for both analog and digital interfaces (with option B2):
With the addition of option B2, the UPL06 can supply a wide variety of digital test signals:
For continuous variation of the test signals the UPL06 offers amplitude and frequency sweeps, and for sine and sine squared bursts, additional sweeps of the interval and the on-time.
The R&S UPL06 is also capable of spectrum analysis. The number of samples for FFT can be selected between 256 and 16k binary steps. FFT Zoom is a special feature is digitaly preprocessed to increase the frequency resolution by a factor of 2 to 128 times normal over a selectable range. In this way, a maximum resolution of 0.05 Hz is attained.
Any number of software filters can be defined. Common filters such as weighting, are provided as standard. Further filters can be easily programmed in a few seconds by entering the type (lowpass, highpass, bandpass, bandstop, notch, third octave, or octave), frequency and attenuation.
The R&S UPL06 was designed for audio measurement of sound cards, multimedia cards, R&D of hearing aids, and production test of audio equipment.
Features of the UPL06 include:
The UPL06 audio analyzer offer increased voltage input range, low-distortion generators, and jitter susceptibility to meet the revised AES17 standard.
