Record & Stimulate

Data capture

Spike2 records waveform, time-stamp and marker data. Waveform channels can be captured at different sampling rates, with synchronising stimulus and pacing pulses logged as time-stamp data to the same file. Text comments placed in the record during data sampling are easily located for review and analysis of experiment stages.

Data feature detection

Active cursors search for features in waveform data and latch to time-stamps. You can also position cursors with "expressions", such as , Cursor (1) +5 to force a second cursor five seconds in advance of the first for comparative area measurements.

  • Search for features including peaks, troughs, threshold crossings, slope measurements, percentage repolarisation and event markers on multiple data channels
  • Use up to ten active cursors in a data file view

BP and ECG with generated mean BP


The CED 1401 interface generates pacing pulses and stimulus amplitude values via Spike2's built-in sequencer. A graphical editor with drag-and-drop interaction allows fast and easy creation of stimulus protocols. For more complex output and control requirements, a text editor enables direct access to the sequencer code. Further on-line control of the outputs is available through script interaction.

  • Output pulse trains, variable amplitude pulses, ramp, sine and arbitrary waveforms during sampling
  • Respond in real-time to changes or features in the sampled data
  • Switch between different output protocols with a mouse-click

Graphical sequence editor


Spike2 can perform on-line and off-line detection of waveform features and mark these in a new channel in the data file using the built-in active cursor and measurement functions. This video tutorial shows how to generate heart rate from a blood pressure trace.

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. ×
