Example MATLAB script to implement the Lock-in Amplifier (plotting)
%% Plotting Lock-In Amplifier Example % % This example demonstrates how you can configure the lock-in amplifier % instrument and monitor the signals in real-time. % % (c) 2017 Liquid Instruments Pty. Ltd. % %% Connect to your Moku ip = input('Please enter your Moku:Lab IP address: ', 's'); % Connect to your Moku and deploy the desired instrument m = MokuLockInAmp(ip); %% Configure the instrument % Output a 1MHz sine wave but demodulate at a harmonic (2MHz) m.set_demodulation('internal','frequency',2e6); m.set_lo_output(1.0,1e6,0); % Output the 'X' (I) signal and the local-oscillator sine wave on the two % DAC channels. Configure a PID controller on the main 'X' output with a % proportional gain of 10x, integrator cross-over of 10Hz and integrator % saturation at 100x. m.set_outputs('X','sine') m.set_pid_by_frequency('main','kp',10,'i_xover',10,'si',100); % Monitor the I and Q signals from the mixer, before filtering m.set_monitor('A','I'); m.set_monitor('B','Q'); % Trigger on Monitor 'B' ('Q' signal), rising edge, 0V m.set_trigger('B','rising', 0, 'hysteresis', 0.01); % View +-1usec, i.e. trigger in the centre m.set_timebase(-1e-6,1e-6); % Get initial data frame to set up the plot data = m.get_realtime_data(); % Set up the plots figure lh = plot(data.time, data.ch1, data.time, data.ch2); xlabel(gca,'Time (sec)') ylabel(gca,'Amplitude (V)') %% Receive and plot new data frames while 1 data = m.get_realtime_data(); set(lh(1),'XData',data.time,'YData',data.ch1); set(lh(2),'XData',data.time,'YData',data.ch2); axis tight pause(0.1) end
