Rohde & Schwarz UPD Audio Analyser

Rohde & Schwarz UPD Audio Analyser Description:

The Rohde & Schwarz UPD performs practically all types of audio measurement, from frequency response measurements through 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 audio analyzers, UPD is capable of performing real dual-channel measurements in the audio-frequency range, ie there is no need for switchover between two inputs and this type of measurement is not limited to a few special cases.

The generator is every bit as versatile: it supplies any conceivable signal from sinewave and noise signals through to multi-sinewave signals comprising up to 7400 frequencies.

In addition to all this, UPD features excellent technical data: analog sinewave generation with harmonics of typ. -120 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 0.02 Hz, etc.

UPD provides signal monitoring via loudspeaker, jitter measurements on digital audio signals, resynchronization of jittered digital audio signals by means of a jitter-free clock signal, and many more features.
