How are the phase and frequency precision characterized for Moku's phasemeter?

Published February 26th, 2021 by Max Deng

The frequency and phase precision of Moku's phasemeter is calculated based on the amplitude spectral density (ASD) of the measured frequency and phase time trace with a reference oscillator input at a given frequency range. For example, the frequency precision for Moku:Lab phasemeter is specified as: This means, for an input reference signal at 5 MH

How do I demodulate a signal at a higher harmonic with an external (PLL) reference?

Published March 24th, 2021 by Max Deng

Moku:Lab's Lock-in Amplifier (LIA) uses a phase-locked loop (PLL) to capture the external reference signal and then generates a pair of sine waves at the same frequency to demodulate the input signal. The PLL does not have a built-in frequency multiplier. However, it may be possible to manually set the PLL frequency to capture the reference at a hig
