The Rohde & Schwarz UPL66 Audio Analyzer performs practically all types of analog measurements, from frequency response to exteally 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 UPL66 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 UPL66 and UPL06 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 UPL66 Audio Analyzer offers a large selection of functions for both analog and digital interfaces (with option B2). The UPL66 and UPL06 have the exact same technical specifications with the difference being that the UPL66 does not have a front panel display or keyboard as does the UPL66. The UPL66 is controlled exteally. The UPL66 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.
