Panasonic vp-7723B audio analyzers
Panasonic VP-7723B Audio Analyzers Description
Panasonic VP-7723B Audio Analyzers is equipped with measurement functions of AC level, DC level, Distortion, Frequency and Wow & Flutter( Factory Option ). VP-7723B is equipped with a low distortion signal source. In addition to various filters including 20 kHz pre-LPF which are essential for digital audio measurement, the audio analyzers have pre-set memory, judgment function, auto sequence function, GP-IB and remote control interface.
- 5 Hz to 110 kHz, 16.2 dBm(14.0 dBV, 10 V at open end)
- 0.000 5 % distortion(1 kHz typical value)high performance signal source
AC level measurement: The audio analyzer has a highly sensitive AC level measurement function with indication response selectable from V [rms] or V [avg]. Seven measurement ranges are provided; 0.316 mV, 3.16 mV, 31.6 mV, 316 mV, 3.16 V, 31.6 V and 100 V full range.
Relative level measurement: Deviation measurement against reference level is available. It is applied to frequency characteristics and level ratio measurement.
Watt indication: By setting the imaginary load resistance (RL)across the input voltage, the power value is s calculated and displayed. Power=(Measured AC level l value)2/RL [watt] ]
S/N measurement(VP-7723B) : In this mode, the oscillator is turned on for a length of time(1.5 to 3 s)and the signal component(S component level)is measured. Then, the oscillator turns off and the noise component(N component level)is measured when the input of the DUT is terminated with the characteristic impedance. The S/N ratio is obtained automatically by calculating the output signal(S component level)and N component level ratio.
Available for +B voltage measurement.
The audio analyzer is capable of measuring distortion factors of the fundamental signal over the frequency range of 5 Hz to 110 kHz. Input level ranges from 0.1 V to 100 V [rms]. Also a high sensitivity 3.16 mV range is provided for the dynamic range measurement of digital audio equipment.
Reciprocal type high speed counter is installed.
This function is available in AC level, Distortion and Wow & Flutter measurement modes
