(NL125, NL126) Filters

Product Summary

These filter modules employ two active filter sections to control high and low pass characteristics.

  • Low frequency cutoff set continuously from 0.5 Hz to 5 kHz
    • Using single-turn potentiometer in four switched ranges
  • High frequency cutoff set continuously from 5 Hz to 50 kHz
    • Using single-turn potentiometer in four switched ranges

The NL125 and NL126 Filter modules employ two active filter sections to control high and low pass characteristics. The low frequency cutoff point can be set continuously from 0.5 Hz to 5 kHz with a single-turn potentiometer in four switched ranges. Similarly the high frequency cutoff can be set continuously from 5 Hz to 50 kHz in four switched ranges. DC and wide band switch positions by-pass the lower and upper filter sections respectively. An active notch filter is provided for the rejection of line frequency interference, set at the factory to 50 Hz (NL125) or 60 Hz (NL126), with a 20 Hz notch width (-3 dB points).
