CFL 9206

Transient Limiter

CFL 9206zoom
  • Helps to protect spectrum and measuring receivers from damage
  • Filters very low frequencies <9 kHz
  • 10 dB Attenuator


The CFL has been designed to interface between a transducer (antenna, line network) and measuring equipment (receiver, spectrum analyzer). The CFL 9206 assists in preventing damage to input circuits of measuring equipment from high level transients often encountered during conducted emission testing. The CFL 9206 incorporates a band pass filter and 10 dB high power attenuator. The maximum input power ratings are for signals within the CFL 9206 passband.
