Audio Analyzer UPL performs practically all types of analog 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, UPL 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 facility 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, UPL features excellent technical data: analog sine-wave 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 0.05 Hz, etc.

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