Rohde & Schwarz UPD05 Audio Analyzer

The R&S UPD05 Audio Analyzer sets a new standard for comprehensive audio testing, enabling users to perform an extensive range of analog measurements with precision. From frequency response evaluations to externally controlled sweeps with reference traces, this analyzer excels in delivering results. It facilitates advanced measurements such as 3rd-order difference frequency distortion and spectral displays for demodulated wow and flutter signals, providing unparalleled flexibility in audio analysis.

Unlike typical audio analyzers, the R&S UPD05 is engineered for genuine dual-channel measurements within the audio frequency spectrum. This important feature eliminates the need for switching between inputs, thus enhancing efficiency and accuracy in testing scenarios.

Equipped with a versatile generator, the UPD05 can produce an array of signals, including sinewave and noise signals, as well as multi-sinewave signals with up to 7400 frequencies. This versatility makes it a must-have instrument for audio engineers and testers.

Exceptional Technical Specifications

• Analog sine-wave generation with harmonics typically reaching -120 dB
• Noise floor below -140 dB for analog interfaces and -160 dB for digital interfaces
• FFT analysis with a maximum frequency resolution of 0.05 Hz
• Real-time signal monitoring via a loudspeaker during tests
• Jitter measurements on digital audio signals
• Resynchronization of jittered digital audio signals using a jitter-free clock signal

The UPD05 harnesses the power of digital signal processing for all measurements. Analog signals undergo sophisticated preprocessing before digitization, ensuring maximum accuracy. For example, during Total Harmonic Distortion (THD) measurements, the fundamental wave is attenuated using a notch filter, with the residual signal then amplified by 30 dB prior to digitization. This process expands the dynamic range beyond the limitations of the internal 20-bit converter, paving the way for future advancements in converter technology.
