The HP Model 4277A LCZ Meter is a fully
automatic, high performance test instrument
designed
to
measure
the
inductance,
capacitance, dissipation factor, quality factor,
conductance,
equivalent
series
resistance,
impedance magnitude, and phase of electronic
components and devices. Its built-in test signal
source covers the frequency range of lOkHz to
IMHz and provides 701 spot frequencies. Test
frequency resolution is lOOHz (maximum), and
frequency accuracy is ±0.01% of the selected
spot
frequency.
Frequently
used
spot
frequencies--!OkHz, lOOkHz, and IMHz—can be
quickly selected by the SPOT key. Test signal
level is selectable at IVrms (HIGH) or 20mVrms
(LOW).
The
instrument's
state-of-the-art
4-terminal pair configuration provides a basic
measurement accuracy of 0.1% over a wide
measurement range.
