Signature and Feature Recording
In
some applications it is not necessary to store all of the information
available in the data streams presented by sensors. An example would be
magnetic anomaly detection used for detecting potential areas of metal
failure in large structures. Only information from the problem areas may
be required, together with their precise locations.
This allows the total amount of recorded data to be reduced, simplifying
analysis, as well as reducing the cost of recording media and storage.
Some features added to the acquisition and recording system are necessary
to support this, and anomaly or signature detection electronics or software
in the recording path have been provided for our products to support this
activity.

This
can be considered to be a reorganisation of system processes to optimise
a generic system for a particular application. Many of our applications
include these features for signature detection, feature detection and
similar semi-intelligent recording decision making.
Artisan, our product for high-speed capture and recording includes many
features found in logic analysers to support this. They include pre and
post signature/feature recording so that the full context of the event
can be viewed during replay time. The equipment is controlled from a graphical
user interface (GUI) to allow complex tasks to be undertaken in a natural
way.
