The MCA Filter accessories are dedicated signal-conditioning devices designed to optimize the quality of analog pulses feeding CAEN Multi-Channel Analyzers. By reducing high-frequency noise and enabling proper AC coupling, these filters improve signal integrity and ensure stable operation with charge-sensitive and transistor-reset preamplifiers.
They are particularly suited for spectroscopy systems based on the 780/781 MCA families, where clean signal transmission and correct baseline behavior are essential for accurate energy measurements.

  • Noise suppression
    Ferrite-core BNC filter for high-frequency noise reduction on MCA inputs.

  • AC coupling for TRP preamps
    Boxed AC coupler (4.7 nF) to interface transistor-reset preamplifiers.

  • Signal integrity improvement
    Enhances baseline stability and spectral performance.

  • Direct MCA compatibility
    Optimized for CAEN 780 and 781 MCA families.
