Rohde & Schwarz UPL Audio Analyzer
The Rohde & Schwarz 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. The UPL is capable of performing real dual-channel measurements in the audio-frequency range. There is no need for switchover between two inputs and this facility is not limited to a few special cases.
The generator supplies any conceivable signal from sinewave and noise signals through to multi-sinewave signals comprising up to 7400 frequencies.
The Rohde & Schwarz UPL Audio Analyzer 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. The Rohde & Schwarz 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.
Rohde & Schwarz UPL Features:
- Built-in hard disk and disk drive
- Connectors for keyboard, mouse, monitor, printer and plotter
- Centronics interface for connecting printer or network
- Automatic test sequences and measurement programs with universal sequence controller. Easy generation of programs with built-in program generator
