NAME

Lab::Instrument::IOtech488 - IOtech DAC488HR four channel voltage source

SYNOPSIS

use Lab::Instrument::IOtech488;

my $gate14=new Lab::Instrument::IOtech488({
    GPIB_board   => 0,
    GPIB_address => 11,
    channel      => 1,
});
$gate14->set_range(6);  # 2 volt unipolar

$gate14->set_voltage(0.745);

print $gate14->get_voltage();

DESCRIPTION

The Lab::Instrument::IOtech488 class implements an interface to the 7651 voltage and current source by Yokogawa. This class derives from Lab::Instrument::Source and provides all functionality described there.

CONSTRUCTORS

new({})

my $gate14=new Lab::Instrument::IOtech488({
    GPIB_board   => 0,
    GPIB_address => 11,
    channel      => 1,
});

METHODS

set_voltage($voltage)

get_voltage()

set_range($range)

# Ranges
# 1 -  1 volt bipolar
# 2 -  2 volt bipolar
# 3 -  5 volt bipolar
# 4 - 10 volt bipolar
# 5 -  1 volt unipolar
# 6 -  2 volt unipolar
# 7 -  5 volt unipolar
# 8 - 10 volt unipolar

A change of range will set the output to zero!!!

get_info()

Returns the information provided by the instrument's 'U9' command.

reset()
