The uniquely designed SR600 series is a programmable elliptical filter that is composed of three dual-channel device and in every instrument channel it is includes a low-noise preamplifier, a precision high-pass which can be low-pass filter section, and an output amplifier. .独特的sr600系列是一个可编程的椭圆滤波器由三个双置每个仪器是包括一个低噪声前置放大器可低滤波器分精度出放大器。。The cutoff frequencies can be modified between the range of 1 Hz and 100 kHz thus, creating the SR600 Series suitable application for any anti-aliasing, audio analysis, and frequency-domain signal conditioning..截止率可以修改之的围为1 Hz和100 kHz因此创建sr600系列用于任何反样分析域信号的。The filters are made of 8-pole with 6-zero elliptic-type and 115 dB in every octave rolloff with 0.1 dB of passband ripple, and 80 dB of stopband attenuation.滤器是用在每个倍程减0.1 dB的带纹波6-zero椭圆型和115 dB和80 dB的8极带减。
