NAME

Lab::Moose::Instrument::ZI_MFLI - Zurich Instruments MFLI Lock-in Amplifier.

SYNOPSIS

 use Lab::Moose;

 my $mfli = instrument(
     type => 'ZI_MFLI',
     connection_type => 'Zhinst',
     connection_options => {
         host => '132.188.12.13',
         port => 8004,
     });

 $mfli->set_frequency(value => 10000);

 # Set time constants of first two demodulators to 0.5 sec:
 $mfli->set_tc(demod => 0, value => 0.5);
 $mfli->set_tc(demod => 1, value => 0.5);

 # Read out demodulators:
 my $xy_0 = $mfli->get_xy(demod => 0);
 my $xy_1 = $mfli->get_xy(demod => 1);
 say "x_0, y_0: ", $xy_0->{x}, ", ", $xy_0->{y};

METHODS

If the MFLI has the Impedance Analyzer option, calling some of the following setter options might be without effect. E.g. if the Bandwith Control option of the Impedance Analyzer module is set, manipulating the time constant with set_tc will not work.
