Pass through, otherwise, test does not pass through.It, can will be current more than preset audio parameter value by the way that superelevation audio parameter threshold is arranged
Audio frequency parameter value is compared again, and further screening improves wireless more than the present video parameter value of preset audio parameter value
The testing efficiency of earphone ensures that more effective audio frequency parameters pass through test.If for example, default snr value be 70dB~
120dB is 121dB by the current SNR value that the PCBA of wireless headset is tested, and therefore, the current SNR value is not
In default snr value, obtain " test does not pass through " as a result, to trigger secondary comparison.Again because of the current signal
Be worth (121dB) and be more than the default snr value (120dB), so directly carry out step S63, by the current SNR value and

The current distortion angle value, the current separation angle value, the current receiving sensitivity residual noise value, the current maximum are groaned
Sound value, the current squelch level value and the current frequency response and the ultralow output power threshold value, the ultralow letter

Test passes through, and otherwise, test does not pass through.By the way that ultralow audio frequency parameter threshold is arranged, preset audio parameter value can be will be less than
Present video parameter value is compared again, and further screening is improved less than the present video parameter value of preset audio parameter value
The testing efficiency of wireless headset ensures that more effective audio frequency parameters pass through test.For example, if default snr value is 70dB
~120dB is 69dB, therefore, the current SNR value by the current SNR value that the PCBA of wireless headset is tested
Not in default snr value, obtain " test does not pass through " as a result, to trigger secondary comparison.Again because of the current noise
Ratio (69dB) is less than the default snr value (70dB), so directly carry out step S64, by the current SNR value and
Ultralow audio frequency parameter threshold is compared, and the ultralow audio frequency parameter threshold is 65dB, it follows that the current signal
Value is more than the superelevation audio parameter threshold, passes through to the superelevation test of secondary comparison, final testing result is " PASS ".
