Lock-in Amplifier User Manual

Software integrations

Wirelessly configure and monitor your Lock-in's performance, all from an
intuitive iPad interface, or with Python, MATLAB, and LabVIEW.

Flexible inputs

The Lock-in Amplifier’s signal and reference inputs can be configured for AC or DC coupling and 50 Ω or 1 MΩ input impedance.

Dual-phase demodulation

Moku:Lab’s Lock-In Amplifier features a dual-phase demodulator with cascaded single pole low-pass filters to attenuate the second harmonic and suppress noise in each quadrature.

  • Select between 6, 12, 18, and 24 dB / octave lowpass filter slopes
  • Select between rectangular (X/Y) and polar (R/θ) coordinate modes
  • View the demodulated in-phase and quadrature signals prior to the low-pass filters using the integrated Oscilloscope

Internal and External

Demodulate your input signal with an internal or external reference. In internal mode, the orthogonal reference signals are generated internally using a direct digital synthesizer (DDS). In external mode, you can select between either direct or phase-locked options. In direct external mode, the input signal is demodulated using the reference input signal for single-phase demodulation (X). The phase-locked loop option reconstructs two orthogonal references that are phase-locked to the reference input signal to support external dual-phase demodulation (XY/Rθ).

Integrated Oscilloscope

Monitor up to two signals at a time using the Lock-In Amplifier’s integrated 2 channel, 500 MSa/s oscilloscope, and continuously log data at up to 1 MSa/s using its built-in data logger.

PID Controller

Moku:Lab’s Lock-In Amplifier can serve as both a sensor and feedback controller with its built-in PID Controller. The PID controller provides real-time control over proportional, integral and derivative gain profiles with configurable saturation.
