多功能声校准器
多功能声校准器可根据EN/IEC 60942 / ANSI S1.40标准对传声器、声级计和其他声学仪器进行模拟自由场校准。
4226 型
多功能声校准器4226可产生频率从31.5 Hz到16 kHz的准确且稳定的声压，以倍频程步进方式，外加一个12.5 kHz的信号。
Using the coupler provided, the test signal can be applied to either ½-inch or ¼-inch microphones, or picked up from an electrical output. For ease of use, Type 4226 can also apply a very accurate inverse A-weighting correction.
An external generator can be connected to Type 4226 if a frequency sweep or semi-automatic test is desired.
