Power1401 history


Conceived as a 1401 for much more demanding acquisition and control tasks, the Power1401 has much more memory and much faster processors than the lower performance micro range of interfaces. The Power mkII was the first to use a fan to cool the processor. It was also the first to receive a front panel mounted on/off switch.

All in the Power1401 range are able to have their firmware upgraded via the host interface and try1401 program. This removes any need to access the circuit boards unless the user is expanding the number of inputs and outputs.

The internal and external metalwork is fundamentally the same as for the micro1401 but has been widened to fit a standard 19 inch rack allowing for more front and rear panel connections on the base unit. Rack mount ears are supplied free of charge at time of purchase.

Rear panel digital I/O connections are the same for all Powers and the 3, the MkII and 625kHz units share the same high density analogue expansion 37 way D type. The original MkI had a low density 25 pin D type connector. Unlike the Micro, the Power1401s have eight ADC inputs on the rear analogue expansion connector.

These are always elevated to the last numbered ADCs in the range, so if an ADC 16 expansion card were added then the rear ADCs move from port numbers 8-15 and become ports 24 through 31.

Comparison of data rates and processor speeds depends on the application. These processor speeds were measured for a 4096 point FFT.

The Power-3 was replaced by the Power-3A in August 2016. The 3A is essentially the same as the 3, but has features re-designed for manufacturing convenience. We took the opportunity to make some minor improvements.

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. ×
