TMS with magnetic stimulators

Signal's built-in auxiliary states system provides direct control of magnetic stimulators during sampling, including adjusting stimulus amplitude and timing and checks on stimulator condition. All settings are stored with the corresponding data frame.
See a video demonstration or our TMS application guide.

  • Control Magstim 200, dual 200, BiStim and Rapid, Magventure MagPro R30 and X100, Deymed DuoMAG, or mag & more PowerMAG stimulators via serial line
  • Set power output and inter-pulse timing settings for different stimulus protocols using multiple states
  • Trigger stimulation using CED 1401 digital outputs for precise pulse timing relative to sampling
  • Stimulation parameters for power level, pulse interval, secondary power level and pulse frequency are automatically saved to the data file

Example TMS setup with a Power1401, dual 1902
amplifier and Magstim BiStim²

Multiple sampling conditions

Signal includes a comprehensive multiple output states system that can be used to setup different sets of outputs. The order and repeat of each stimulus can be sequenced using a pre-defined protocol or executed semi-randomly or randomly. Each sweep of recorded data is marked to indicate the stimulus that was used and analysis such as waveform averaging and automated measurements can be applied to specific states or state combinations on-line and off-line - see a video demonstration

  • DuoMAG
  • Magstim
  • Magpro
  • PowerMag


Multiple states control of supported Magstim devices is achieved using the auxiliary states module in Signal. The Magstim button in the States tab then allows the user to configure settings for Magstim 2002, BiStim2 or Rapid devices. This video tutorial demonstrates how to set up Magstim configurations in Signal.


You can generate a waveform average both on-line and off-line by selecting the Waveform Average function from the Analysis menu, New memory view option. This video tutorial demonstrates how to create averages in Signal.

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. ×
