Audio signal oscillator
??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 Measurement
??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.
DC Measurement
??0.316 to 100 V full scale
??Available for +B voltage measurement.
Distortion 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.
Frequency Measurement
??Reciprocal type high speed counter is installed.
??This function is available in AC level, Distortion and Wow & Flutter measurement modes
