=head1 NAME

Lab::Moose::Instrument::Keithley2400 - Keithley 2400 voltage/current sourcemeter.

=head1 VERSION

version 3.880

=head1 SYNOPSIS

 use Lab::Moose;

 my $source = instrument(
     type => 'Keithley2400',
     connection_type => 'LinuxGPIB',
     connection_options => {gpib_address => 15},
     # mandatory protection settings
     max_units_per_step => 0.001, # max step is 1mV/1mA
     max_units_per_second => 0.01,
     min_units => -10,
     max_units => 10,
 );

 ### Sourcing


 # Source voltage
 $source->source_function(value => 'VOLT');
 $source->source_range(value => 210);

 # Step-sweep to new level.
 # Stepsize and speed is given by (max|min)_units* settings.
 $source->set_level(value => 9);

 # Get current level from device cache (without sending a query to the
 # instrument):
 my $level = $source->cached_level();

 ### Measurement

 # Measure current
 $source->sense_function_on(value => ['CURR']);
 # Use measurement integration time of 2 NPLC
 $source->sense_function(value => 'CURR');
 $source->sense_nplc(value => 2);

 # Get measurement sample
 my $sample = $source->get_measurement();
 my $current = $sample->{CURR};
 # print all entries in sample (Voltage, Current, Resistance, Timestamp):
 use Data::Dumper;
 print Dumper $sample;

=head2 set_level

 $source->set_level(value => $new_level);

Go to new level. Sweep with multiple steps if the distance between current and
new level is larger than C<max_units_per_step>.

=head2 get_measurement

 my $sample = $source->get_measurement();
 my $current = $sample->{CURR};

Do new measurement and return sample hashref of measured elements.

=head2 cached_level

 my $current_level = $source->cached_level();

Get current value from device cache.

=head2 get_level

 my $current_level = $source->get_level();

Query current level.

=head2 set_voltage

 $source->set_voltage($value);

For XPRESS voltage sweep. Equivalent to C<< set_level(value => $value) >>.
