Voltage induced in secondary coils and corresponding TTL signal as function of time.
1st, 3rd, and 5th even component of induced voltage for arbitrary source phase and phase shifted for 10°, 20°, and 30° as a function of detector phase. Arrow shows shift of source phase, same for all three harmonics.
RMS amplitudes of real (down) and imaginary (up) Fourier components of induced voltage obtained from fit of digitized voltage (full dots) and directly measured on Ametek 7265 lock-in (empty dots).
Voltage measured in first channel of PAR 5210 lock-in (in FLAT mode) as the function of lock-in phase.
Hysteresis obtained by: integration of digitized induced voltage (elongated one), constructed from 50 harmonics measured by Ametek 7265, and directly measured by PAR 5210 lock-in. Latter two almost coincide.
