BASIC MEASUREMENT

Reactance (X) and Susceptance (B = 1/X)
Background Reactance measures the imaginary part of
Impedance (Z) caused by capacitors or inductors.
Susceptance is the reciprocal of Reactance and
measures the imaginary part of Admittance (Y),
which is also the reciprocal of Impedance.
Type Series Reactance (X
S
)
Note: Reactance is
available only in series
circuit model.
Parallel Susceptance (B
P
)
Note: Susceptance is
available only in parallel
circuit model.
Display Range 0.01mΩ ~ 1GΩ 0.001ns ~ 1ks
