Model: Stanford Research Systems / SRS SR650     Condition: Reconditioned

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.

Model - Configuration

  • SR640 - Dual Low Pass
  • SR645 - Dual High Pass
  • SR650- High Pass/Low Pass (can be cascaded for Band Pass)

Inputs and Preamplifiers

Each filter channel has a floating, differential input with 1 MW input impedance and 6 nV/ÃHz of input noise. The analog ground for each filter channel is available at a rear-panel BNC connector to provide complete flexibility in grounding. The filter grounds may be tied to the instrument's chassis ground or to any other point. Both AC and DC input coupling can be selected, and an invert key allows the phase of the signal to be shifted by 180° with a single key press. Up to 60 dB of preamplifier gain can be specified in 10 dB increments. A simple offset adjust screw lets you null DC components in your signal.

Features

  • Two independent filter channels
  • 115 dB/octave rolloff
  • 1 Hz to 100 kHz frequency range
  • 0.1 dB passband ripple
  • 80 dB stopband attenuation
  • 6 nV/Hz input noise
