New Spike2 version 9

Major new features include:

  • Talkers. The Talker system allows devices other than a CED 1401 interface to stream real-time data into a sampling data file. We have extended the range of available devices and improved their operation in version 9 so that you can sample Talker data without the need for a 1401 device. See Talker details for information on the available devices.

  • Channel counts. Spike2 data files, memory channels, virtual channels, result views and XY views can now all have up to 2000 channels.
  • Grid Views. The maximum rows in a grid view is increased to 1,000,000.
  • Arbitrary waveform output. The maximum number of waveforms that can be stored in a 1401 for playback as a stimulus is increased from 10 to 20 in Micro1401s and to 62 in Power1401s.
  • Script language. There are new operators for the script language, including left and right shifts.
  • User interface. More dialogs are resizeable and more adjustments made to take advantage of high-resolution displays.

New Power1401-3A

We have upgraded the design of the Power1401 for production reasons. There is no change to the user.

Signal version 6

Speed improvements have been introduced with the new 64-bit version of the program over the older 32-bit application. A new memory channel type, RealMark, has been added which allows the addition of a time plus up to thirty two individual floating-point values. This type of channel could hold the time of peaks and their corresponding waveform amplitude. The script language has been extended to support locating, adding, deleting and modifying RealMark data. The virtual channel functions have also been improved to accommodate this new channel type. See history →

More development has taken place in the patch and voltage clamp areas with an improved membrane analysis dialog, a duplicate option in the dynamic clamp models dialog and the addition of an optional rectification mode in the noise model. Both standard voltage based telegraphy and the auxiliary telegraphing system can also now operate simultaneously. See details →

New CED 4401 Frequency multiplier

The CED 4401 is designed for use in locking the sampling clock of a CED 1401 data acquisition unit to an external reference frequency, such as those encountered in other sampling systems. Suitable inputs are TTL signals that are stable sub-multiples of 20MHz. The CED 4401 takes this frequency and multiplies it up to the 20MHz needed to feed the external synchronising input of a CED 1401. The power LED on the CED 4401 turns from red to green when a usable input frequency is detected. See details →

New CED 4302 5V signal offsetter

The CED 4302 is a single channel signal offsetter. It adds or subtracts an accurate 5V offset to an analogue input. It is designed for recording unipolar (0V to 10V or -10v to 0V) signals using a ±5V recording system, or for driving equipment that has a unipolar input from bipolar (±5V) output devices.

New CED 4301 Low Pass Filter

The CED 4301 is a single channel 10th order low-pass filter with manual control of cut-off frequency from 600Hz to 40kHz in 3 switched ranges. The filter passband response is a root-raised-cosine, which gives an almost linear phase characteristic. See details →

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.

Cookies

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. ×
