Dual-phase demodulation

The Moku:Lab 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 references

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). Additionally, the mixer stage can be bypassed for additional closed-loop control applications.[/lq_image_text][lq_image_text image=”5074″]

Integrated PID controller, oscilloscope, data logger

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. Additionally, the PID controller provides real-time control over proportional, integral, and derivative gain profiles with configurable saturation.[/lq_image_text][lq_image_text image=”5086″ image_position=”Right”]
