Axon Digidata 1550B

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

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.


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.
