The SR770 and SR760 are both single-channel, FFT and 100kHz spectrum analyzers that have real-time bandwidth of 100kHz and dynamic range of 90dB. The SR770 has a low-distortion source that allow the measure of transfer functions of both mechanical and electronic systems..sr770 sr760的和无是单信FFT和100kHz的分析仪具有100kHz动态围90dB实时带宽。sr770的具有低失真源允的机械和电子系统的传函数的措施。The dynamic range and speed of these instruments make them the ideal choice for different applications that include general electronic noise, noise measurement, vibration and acoustics.些仪器的动态围和度使它们为不同的应用包括一的电子噪声噪声测的理想择振动和声学。
