1.1 Overview and Features
The HIOKI IM7580 Impedance Analyzer is an impedance measuring instrument that has achieved high
speed and high accuracy.
The IM7580 combines the functionality of two devices: an impedance analyzer that can perform frequency
and sweep measurement of measurement signal, and an LCR meter that can simultaneously display up
to four parameters under a single set of measurement conditions.
A wide range of measurement conditions can be set and the instrument can be used across a broad
range of applications such as measurement of high frequency inductors.
Wide range of
measurement
conditions
•Measuring frequency of IM7580 is from 1 MHz to 300 MHz.
• Measurementsignallevelisfrom-40dBmto+7dBm.
Fast measurement Measurement speed is 0.6 ms (typical value) at the fastest.
Graph display
The measurement frequency and sweep function of measurement level
allow frequency characteristics and level characteristics to be measured
and displayed as a graph on the color LCD display of the instrument.
Cole-Coleplotandadmittancepiegraphcanalsobeeasilydisplayed.
Equivalent
circuit analysis
Itprovidesvetypesofequivalentcircuitmodelsforcircuitelementsand
components.
CONTINUOUS
measurement mode
Capable of continuous measurements using measurement conditions
stored in the memory of the instrument. This function enables making
pass/failjudgmentwithdifferentmeasurementconditions.
(Example:PerformsC-Dmeasurementwith1MHzandLsmeasurement
with 100 MHz in succession.)
Various interfaces
supported
SupportwiththemostsuitableEXTI/O(handlerinterface),USB,GP-IB,
RS-232C,andLANforproductionlines.
*GP-IBandRS-232Careoptional.
Comparator
function
•LCR mode: (p. 46)
CapableofmakingHI/IN/LOpass/failjudgmentsbasedonthe
measured values for the four parameters.
• ANALYZERmode:(p.112)
Capableofmakingpass/failjudgmentforsweepmeasurementresults.
BIN function WithLCRmode,therankcanbedividedupto10classicationsbased
on the measured values.
