NAME

Lab::Moose::Sweep::Continuous - Base class for continuous sweeps (time, temperature, magnetic field)

VERSION

version 3.720

SYNOPSIS

use Lab::Moose;

#
# 1D sweep of magnetic field
#

my $ips = instrument(
    type => 'OI_Mercury::Magnet'
    connection_type => ...,
    connection_options => {...}
);

my $multimeter = instrument(...);

my $sweep = sweep(
    type => 'Continuous::Magnet',
    instrument => $ips,
    from => -1, # Tesla
    to => 1,
    rate => 0.1, (Tesla/min, always positive)
    start_rate => 1, (optional) rate to approach start point
    interval => 0.5, # one measurement every 0.5 seconds
);


# alternative: points/rates
# my $sweep = sweep(
#     type => 'Continuous::Magnet',
#     instrument => $ips,
#     points => [-1, -0.1, 0.1, 1],
#     # start rate: 1
#     # use slow rate 0.01 between points -0.1 and 0.1
#     rates => [1, 0.1, 0.01, 0.1], 
#     intervals => [0.5], # one measurement every 0.5 seconds
# );


my $datafile = sweep_datafile(columns => ['B-field', 'current']);
$datafile->add_plot(x => 'B-field', y => 'current');

my $meas = sub {
    my $sweep = shift;
    my $field = $ips->get_field();
    my $current = $multimeter->get_value();
    $sweep->log('B-field' => $field, current => $current);
};

$sweep->start(
    datafiles => [$datafile],
    measurement => $meas,
);

DESCRIPTION

Continuous sweep constructure. The sweep can be configured with either

• from/to

• rate

• interval (default: 0)

or by providing the arrayrefs

• points

• rates

• intervals (default: [0])

If an interval is 0, do as much measurements as possible. Otherwise, warn if measurement requires more time than interval.

Do backsweep if backsweep attribute is set to 1.
