Data acquisition

  • Record to the 64-bit format of virtually unlimited size and duration or use the established 32-bit format for backwards compatibility
  • Set different waveform sample rates per channel
  • Capture and classify single and multi-unit spike activity in real-time
  • Continuous, internally timed and triggered recording modes
  • Store up to 8 channels of event data with microsecond timing resolution
  • Log accurately timed coded 8-bit digital inputs
  • Annotate data records with text notes and keyboard markers
  • Sample data from other equipment using the CED Talker interface

Spike2 sampling configuration dialog

  • Swap between experiment setups quickly with a single mouse click
  • Calibrate waveforms with multiple methods including values, areas, slopes
  • Automatically save and sequence multiple files with optional trigger start
  • Recover data files in the event of an un-commanded system shutdown
  • Configure dynamically programmable amplifiers including the CED1902, the Digitimer D360 and D440 and the Power1401 gain option

System requirements

Spike2 version 9 requires a CED Power1401, a Micro1401-3 or Micro1401Mk II intelligent laboratory interface and a PC with Windows 7, 8 or 10, or an Intel Macintosh running Windows. See the compatibility table. The computer must be modern enough to support the SSE2 instruction set. We recommend that the PC has a minimum of 4GB RAM.

Both 32-bit and 64-bit versions of Spike2 are supplied: either version of the software can be used on systems running a 64-bit OS. The 64-bit version provides a performance increase and access to more memory.

Test computer for SSE2 compatibility

The latest versions of Spike2 and Signal require the SSE2 instruction set extension to the IA32 (x86) instruction set. It started to be added to Intel 32-bit CPUs in 2000 and to AMD CPUs in 2003. All 64-bit capable CPUs support this. The following link has a little more information:

If you are unsure about your computer, to test it for compatibility, please download, extract SSE2check.exe and run it to get a direct answer. ×


TextMarks are a special type of marker that can be used to enter notes and comments during a recording. This video tutorial demonstrates how to use TextMarks to annotate a data file.

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. ×
