FUNCTION OVERVIEW

Measurements
& Judgments
1) Sound pressure level (SPL) frequency response
2) 2nd, 3rd & total harmonic distortion characteristics
3) Rub & buzz frequency response
4) Impedance characteristics
5) Polarity & Phase characteristics
6) Sensitivity (S0)
7) Lowest resonance frequency (f0)
8) Impedance (Z0)
9) Isolation Test
Above are tested by 1 sweep if driving voltage is the same
If voltage is different, they can be tested by multiple sweeps
