VERSION

version 3.841

SYNOPSIS

Ths general VISA Connection class for Lab::Bus::VISA digests VISA resource names.

This is not called directly. To make a VISA suppporting instrument use Lab::Connection::VISA, set the connection_type parameter accordingly:

$instrument = new HP34401A( connection_type => 'VISA', resource_name => 'GPIB0::14::INSTR', )

DESCRIPTION

Lab::Connection::VISA provides a VISA-type connection with Lab::Bus::VISA using NI VISA (Lab::VISA) as backend.

It inherits from Lab::Connection.

CONSTRUCTOR

new

 my $connection = new Lab::Connection::VISA(
   connection_type => 'VISA',
   resource_name => 'GPIB0::14::INSTR',
 }

METHODS

This just falls back on the methods inherited from Lab::Connection.

config

Provides unified access to the fields in initial @_ to all the child classes. E.g.

 $GPIB_Address=$instrument->Config(gpib_address);

Without arguments, returns a reference to the complete $self->Config aka @_ of the constructor.

 $Config = $connection->Config();
 $GPIB_Address = $connection->Config()->{'gpib_address'};

CAVEATS/BUGS

Probably few. Mostly because there's not a lot to be done here. Please report.
