PSM1700 PsimetriQ user manual
14-3
PsimetriQ measures the real and imaginary components at
the fundamental frequency using DFT analysis as
described in the section on gain/phase analysis. The
frequency may be taken from its own generator or from
the circuitry under test.
From the fundamental components of voltage, (a + jb),
and those of the current, (c + jd), PsimetriQ computes the
complex impedance given by:
z = v / i
= (a + jb) / (c + jd)
The components of the complex impedance are filtered
independently to minimise the effects of noise, which
would have random phase and would therefore be filtered
out.
The magnitude of the voltage and current are also
computed.
From the complex impedance the following parameters can
be derived:
ac resistance
inductance,
capacitance
impedance (magnitude, resistance and reactance)
phase
tan (= real/imaginary)
Q factor (= imaginary/real)
Values are displayed for both series and parallel
configurations.
Optionally, the values can be expressed as admittance,
conductance, and susceptance instead of impedance,
resistance and reactance.
