Panasonic VP-7725D

VP-7725D Audio Analyzer

INTRODUCTION

The VP-7725D combines a 2-channel signal source (audio oscillator) and a full range of measurement functions to provide the -120 dB distortion measurements needed for testing today’s high precision digital audio equipment.
In addition to low distrotion 5Hz to 10kHz signal source, this new audio analyzer provides 7 major measuremnt functions:

• DC Level
• AC Level
• Distortion (include DISTN, THD & HD)
• S/N
• Ratio
• Frequency
• Wow & Flutter(Option)

The extensive range of filters includes 10kHz Pre-LPF, essential for digital audio measurements, and the large LCD shows measurement results in combination of digital and analog format.

With pre-set memory, limit function, memory auto-sequence function, remote interface and GP-IB, the VP-7725D is an ideal solution for testing high performance audio equipment such as DVD audio and SACD

• 2-channel high-performance, high-output oscillator with low distortion (typically 0.00005% at 1kHz)

• Relative Level Measurement for frequency response, S/N and crosstalk measurements

• The analyzer can be used as a psophometer by selecting average, RMS or Q-peak detection with appropriate built-in filter for noise measurement

• Three kind of distortion measeuremnte with either average or RMS response are available for the 5Hz to 110kHz frequency range.

- DISTN: Measeures THD+N at 0.001% (-100dB) or less.

- THD: Extracts up to the 10th harmonic component. 0,0001% (-120dB) or less for frequencies between 200Hz to 2kHz

- HD: Displays 2nd to 5th harmonic components.
