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 3522-50 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, R s, Cs : The measured values of L, C, and R in series equivalent circuit
mode.
Lp, R p, Cp : The measured values of L, C, and R in parallel equivalent
circuit mode.
