Lab::Moose::Instrument::Keithley2400 - Keithley 2400 voltage/current sourcemeter.
version 3.822
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;
Used roles:
$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 max_units_per_step.
max_units_per_step
my $sample = $source->get_measurement(); my $current = $sample->{CURR};
Do new measurement and return sample hashref of measured elements.
my $current_level = $source->cached_level();
Get current value from device cache.
my $current_level = $source->get_level();
Query current level.
$source->set_voltage($value);
For XPRESS voltage sweep. Equivalent to set_level(value => $value).
set_level(value => $value)
