Example Python script to implement the Lock-in Amplifier

#
# Moku example: Basic Lock-in Amplifier
#
# This example demonstrates how you can configure the Lock-in Amplifier
# instrument to demodulate an input signal from Input 1 with the reference
# signal from the Local Oscillator to extract the X component and generate
# a sine wave on the auxiliary output

from moku.instruments import LockInAmp

# Launch Lock In Amplifier and connect to your device via IP
i = LockInAmp('192.168.###.###', force_connect=False)

try:
    # SetChannel 1 and 2 to DC coupled, 1 Mohm impedance, and 400 mVpp range
    i.set_frontend(1, coupling='DC', impedance='1MOhm',attenuation='0dB')
    i.set_frontend(2, coupling='DC', impedance='1MOhm',attenuation='0dB')

    # Configure the demodulation signal to Local oscillator with 1 MHz and
    # 0 degrees phase shift
    i.set_demodulation('Internal',frequency=1e6,phase=0)

    # Set low pass filter to 1 kHz corner frequency with 6 dB/octave slope
    i.set_filter(corner_frequency=1e3, slope='Slope6dB')

    # Configure output signals
    # X component to Output 1 
    # Aux oscillator signal to Output 2 at 1 MHz 500 mVpp
    i.set_outputs('X','Aux')
    i.set_aux_output(1e6,0.5)
