The SR650 is a Variable filter from Stanford Research. Electronic filters perform a variety of signal-processing functions with the purpose of removing a signal’s unwanted frequency components, enhance desired ones, or both. There are many types of electronic test equipment filters, including those that are passive, active, analog, digital, low pass, high pass, linear, and nonlinear. Linear filters are the most commonly used for most electronic equipment applications.
Additional Features:
Frequency range: 1 Hz to 100 kHz
Two independent filter channels
115 dB/octave rolloff
0.1 dB passband ripple
80 dB stopband attenuation
6 nV/√Hz input noise
Up to 80 dB of gain
GPIB and RS-232 interfaces
Impedance 1 Mω // 15 pF
Type 8-pole, 6-zero elliptic
On the Stanford Research Systems SR650, 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 stopband attenuation. Cutoff frequencies can be set between 1 Hz and 100 kHz, making the SR650 ideal for applications including anti-aliasing, audio analysis, and general frequency-domain signal conditioning.
