The Power1401 is faster, and has more instrumentation ports than the Micro. The Micro has the facilities and the speed that most users need, most of the time.
The Power processor is faster, up to 14x faster and the base memory is 256x larger, enabling more complex on-line analysis, seen for example in spike shape recognition, where both the number of channels and the number of templates can be increased, with much faster shape matching. The Power can manage 32 spike shape channels, the Micro 16.
The number of ports on both models can be considerably expanded, and for very large numbers of signals, several 1401s can be synchronised to each other, or to an external source.
Waveform capture is fast on both. The Micro, multi-channel, can run at 500 kHz, the Power at 1 MHz.
The Power1401 has 16 waveform input ports, compared with 4 waveform inputs on an un-expanded Micro. There is an option of programmable gain on all 16 Power inputs. There are 4 waveform outputs at 16 bit resolution on the Power 1401 and 2 at 16 bits on the Micro. The Power waveform outputs may be increased to 8 with an optional expansion unit.
The Micro1401 is physically smaller, and somewhat lower in cost than the Power1401.

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