8121FT-1 (IEC-268-1) 外接濾波器之說明
Description of Model-8121FT-1 (IEC-268-1)
(1) 8121FT-1 乃是根據(jù) IEC-268-1 規(guī)定所制造的加權(quán)濾波器， 必須配合及連
接的 8121C 之后， 方能產(chǎn)生符合
IEC-268-1 所規(guī)定的加權(quán)濾波雜音， 以進(jìn)行揚(yáng)聲器的壽命試驗(yàn)及訂定揚(yáng)聲
器的額定功率。
8121FT-1 is the weighting filter made in accordance to IEC-268-1 requirement, it must linked with either Model-8121C made by Sunlight Electronics Laboratory, to enable it to generate weighting noise filter that complied with IEC-268-1 requirement , for undergoing the life testing of the loudspeaker and by defining the rated power of the loudspeaker
(2) 使用時(shí)請(qǐng)注意: 輸 入 的 訊 號(hào) 源 是 采 用 粉 紅 查 雜 音 (Pink Noise)，不可使用其
他種類的雜音訊號(hào)源。
