Axon Digidata 1550B Low-Noise Data Acquisition System Plus HumSilencer

Axon Digidata 1550B Low-Noise Data Acquisition System plus HumSilencer

High-resolution, low-noise digitizer with 50/60 Hz line-frequency noise elimination.

The digitizer that enables acquisition of patch-clamp data

The Axon™ Digidata® 1550B plus HumSilencer® is one of the most advanced analog-to-digital signal converters on the market, offering the innovative line synchronous noise-cancelling feature, HumSilencer. This advanced feature learns, adapts, and eliminates local 50/60 Hz line-frequency noise and high-frequency harmonics from incoming signals. The digitizer works with pCLAMPTM 11 Software for data acquisition and analysis. The software supports eight channels of analog acquisition and four acquisition modes.

  • Eliminate line-frequency noise

    HumSilencer removes 50/60 hz line-frequency noise on up to four channels in parallel. The function is quickly enabled through a software checkbox.

  • Record high resolution traces

    All eight analog input channels can be simultaneously digitized at an impressive sampling rate of 500 kHz per channel.

  • Digitize cellular network studies

    With Digidata 1550B system, you can now record cellular networks without 50/60 Hz line-frequency noise in a single digitizer while saving money, time, and reducing hassle.


  • 50/60 hz noise cancellation

    HumSilencer is an advanced feature that learns, adapts, and eliminates local 50/60 Hz line-frequency noise patterns and associated high-frequency harmonics from incoming signal up to 20 V peak-to-peak.

  • Noise canceling

    HumSilencer is not a filter and has no effect on acquired signals. It causes no signal distortion such as frequency change, amplitude attenuation, phase shift, or DC voltage change.

  • Wide range of input signals

    Digidata 1550B digitizes a wide range of input signals from -10 to +10 V.

  • HumSilencer adaptation

    HumSilencer automatically recognizes changes in noise amplitudes and adapts by removing noise in less than one second.

  • Optimized for pCLAMP 11 Software

    The pCLAMP Software suite is the most widely-used patch-clamp electrophysiology data acquisition and analysis program for control and recording of voltage-clamp, current-clamp, and patch-clamp experiments.

  • Three configurations

    Three configurations are available: Digidata 1550B4 with four HumSilencer channels, Digidata 1550B1 with one HumSilencer channel, and Digidata 1550B0 without a HumSilencer channel.
