In addition to all this, the UPD Audio Analyzer 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. The R&S 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.
