• Record sweeps of waveform and marker data, free-running or time-locked to a stimulus or response
  • Perform analysis on-line and off-line including waveform averaging (with error bars), power spectra and amplitude histograms

  • Detect and measure waveform features in raw data and average result views and generate measurement both on and off-line in XY views or channels in the data file
  • Mark detected features and events. Markers can be added interactively, by automated measurement processes or by a script
  • Generate simple and complex protocols of waveform and digital output and modify the output interactively even while sampling

Automated action potential analysis

  • Derive 'virtual channels' defined by user-supplied expressions for channel arithmetic, spectral analysis and stimulus waveform generation
  • Easily manipulate data using menu or keyboard driven functions. Options include rectification, DC removal, smoothing rescaling and time shift
  • Automate and customise analyses and repetitive tasks
  • Digitally filter (FIR and IIR) via interactive dialogs or scripts
  • Configure multiple views of the same data file and overlay data from multiple sweeps and channels, even during sampling
  • Design stimulus outputs graphically, react very quickly to sampled data and apply complex interaction between inputs and outputs with scripts

Action potentials simulated by dynamic clamp

  • Analyse whole-cell voltage and current clamp (leak subtraction, curve fitting) and single channel patch clamp analysis (open/closed time, burst duration histograms etc.)
  • Apply curve fitting using a variety of fit equations; fit coefficients can be plotted automatically to an XY view
  • Simulate ion channels, leaks and synapses with built-in high speed dynamic clamping support. Up to 15 clamping models can be used concurrently when sampling.
  • Import data files recorded with other acquisition systems. Formats include Axon, EDF, HEKA, ASCII and binary
  • Export data to other applications as text, binary or image files, write .mat files to export data to MATLAB®. The Signal data format (CFS) is freely available to programmers wishing to read and write Signal data files

Privacy policy

CED, through this site, does two things that relate to privacy. We would like to explain them.

Emails from down-loads

We offer free down-loads of many files on our site, from test programs to complete install files for updated versions of major packages like Spike2 and Signal.

When customers wish to take a down-load of a major package, we ask a few questions, including their name, email address, the serial number of the software for which they seek an upgrade and whether they would like an automatic email whenever we update the product. This information is emailed back to CED when they access the final down-load screen. Within this email, your browser transmits the type and version of browser you are using, and the screen resolution you are running.

The reasons why we take and keep this information are that it is useful for our software development team to know who has taken the latest versions, and it is useful for our web site development team to know which browsers people are using to view our site, and what resolution they have their screens set to.


When people down-load a major package, we try to write a cookie, a small file in your computer, that records your name, serial number of the software package, and the version you are down-loading. These files have a lifetime of one year.

The reasons for storing this information are firstly that if you ask for another down-load some other time, your details are read from the cookie and are pre-written into the form, to save you looking them up again. The other reason is that next time you access our site, your browser looks through your CED cookies and compares the versions down-loaded with the latest version numbers read from our site. If there is a later version of a product you have already down-loaded, we tell you on the home page screen, so you know that it is worth going to the down-load page again.

None of this information is ever given to anyone outside CED. ×
