Into a high-impedance load (>1.0MΩ).
Must decode signal above -25.2dB; Must Not decode signal below -46.0dB.
If a supply other than 3.3 volts is used, levels will change pro-rata.
Under ‘Pure Tone’ input conditions.
For input frequencies of between 661Hz and 899Hz the FX613 will provide no reliable output.
With an amplitude modulating frequency of between 16.0Hz and 100Hz.
Test noise input = 5.0kHz at 100mVrms
