From the voltage V which is applied between the terminals of the sample
under test, the current I which flows through the test sample at this time, the
phase angle θ between this voltage V and this current I, and the angular
velocity ω which corresponds to the test frequency, the 3532-50 can
calculate the following components by using the calculation equations
shown:
The phase angle θ is shown based on the impedance Z. When measuring
based on the admittance, the sign of the phase angle θ must be reversed.
Ls, Rs, Cs : The measured values of L, C, and R in series equivalent circuit
mode.
Lp, Rp, Cp : The measured values of L, C, and R in parallel equivalent
circuit mode.
