NAME

Lab::Instrument - Worker class for VISA based instrument classes

SYNOPSIS

 use Lab::Instrument;
 
 my $hp22=  new Lab::Instrument(0,22);
 my $id=$hp22->Query('*IDN?');

DESCRIPTION

This class describes a general visa based instrument.

It can be used either directly by the laborant (programmer) to work with an instrument that doesn't have its own perl class (like Lab::Instrument::HP34401A). Or it can be used by such a specialized perl instrument class (like Lab::Instrument::HP34401A), to delegate the actual visa work. (All the instruments in the default package do so.)
