VOLTAGE CONTROL FREQUENCY FILTER

Variable Frequency Filters & Modules
Voltage-Control - APV Series

APV series are best used in recovering or eliminating unknown signal or band of signals by sweeping the cut-off up and down continuously from 0.01 Hz to 100k Hz. It is a basic building block in automation and time sharing signal processing.

Features include:
  • CUSTOMER SPECIFIED PARAMETERS
    Customer defines passband, stopband, roll-off rate, response, & gain.
  • NO SET-UP, NO ENGINEERING CHARGE
    No additional cost besides unit price.
  • HIGH PRECISION
    ± 1% accuracy in -3 dB frequency.
  • ANALOG ACTIVE FILTER
    RC active filter.
    Not switch-capacitor filter.
  • COMPLETELY ASSEMBLED
    Fully Finished module.
    No external component required.
  • FREQUENCY RANGE
    0.01 Hz to 100 kHz
  • 4 STANDARD RESPONSES
    Butterworth, Bessel, Chebyshev, & Elliptic.
  • SUPPORT ALL FILTER FUNCTIONS
    Lowpass, Highpass, Bandpass, & Band-reject.
  • STABLE OUTPUT
    Unity gain output. Amplification available.
  • IDEAL FUNCTION BLOCK
    High input impedance. Low output impedance.
  • COMPENSATED DC OFFSET
    Internal DC offset < 2 mV. External adjustable to 0.0.
  • BUILT-IN DECOUPLING
    Internal power supply decoupling.
  •  < $ 295.00 each >
