channels, depending on the PowerLab model). Both provide many
other powerful features in addition, including computed functions,
triggering options, software-controlled stimulus generation, and
automated recording and analysis. Their user's guides describe them
in full; the Getting Started with PowerLab manual gives summaries.
You must install the software to use your PowerLab. Installation
instructions are included in the user's guides for the software.
ADInstruments Front-Ends
Front-ends are optional ancillary devices that can be connected to the
PowerLab to extend the system's capabilities. They afford additional
signal conditioning and other features, and extend the types of
experiments you can conduct and the data you can record. For
instance, the Bio Amp is available if you need to perform electrically
isolated measurements of biological signals (PowerLabs should never
be connected to humans directly, unless it is through connections
marked as safe). A PowerLab can have as many front-ends connected
to it as it has analog inputs, roughly speaking. Front-ends are easily
added to or transferred between PowerLabs. They are automatically
recognised by the PowerLab system and seamlessly integrated into its
programs, operating under full software control.
Your ADInstruments distributor will have full information on
available front-ends and their uses and specifications, and will be
happy to discuss your requirements.
The PowerLab
It is a good idea to get familiar with some of the external features of
your PowerLab before connecting it to a power source. The rest of
this chapter discusses the different features, connectors, and
indicators of the PowerLab/4
, PowerLab/8
, and PowerLab/16
