The SR600 series consists of three dual-channel instruments. Each instrument channel has a low-noise preamplifier, a precision high-pass or low-pass filter section, and an output amplifier. The filters are 8-pole, 6-zero elliptic-type with 115 dB per octave rolloff, 0.1 dB of passband ripple, and 80 dB of stopband attenuation. Cutoff frequencies can be set between 1 Hz and 100 kHz making the SR600 Series ideal for applications including anti-aliasing, audio analysis, and frequency-domain signal conditioning.
