Required Instrument and fixture
Instrument
E5061B-3L5/005/720 or E5061BEP-NZA
(E5061BEP-NZA is the package solution which has all
required option for impedance analysis)
In this demo, a 0.1 uF leaded capacitor is measured.
You can evaluate other components as well. Also,
you can even evaluate SMD(chip) components if
you have a test fixture for SMD components (16034E
or 16034G).
Fixture
16047E
DUT
Leaded component

b. Press [Display] then press Num of traces , and 2
Press Allocate Traces and x2
c. Set measurement parameters
Press [Meas] the press Impedance analysis menu
Press Method then press GP Series (T 50 ohm, R 1
Mohm)
Press |Z|
Press [Trace Next] to select trace2 then press Cs
d. Set Y-axis to log scale for trace1
Press [Trace Next] to select trace1
Press [Scale] then Y-Axis and Log
What is the method under impedance analysis menu?
There are several topologies (or methods) to measure
impedance depending on the DUT’s impedance range.
With the GP Series (T 50 ohm, R 1 Mohm), Series-
though method at GP (Gain-Phase) port of the E5061B
(port impedance: T: 50 ohm, R: 1 Mohm) is used.
e. Set log sweep parameters
Press [Sweep Setup] then press Sweep type, and

3. Perform calibration
To measure impedance accurately, recommend to
perform calibration. However, if you don’t have
calibration kit, you can skip step 3.
a. Select calibration kit
Press [Cal] then press Cal Kit, and Leaded 50 ohm
b. Measure calibration standard
Press [Cal] then press Calibrate
Press Impedance calibration
Make open state then press Open
Make short sate then press Short
Make load state then press Load
c. Activate calibration
Press Done
Refer to following figure to make each state for the
standard measurement.
Open Load
Short
Insert short bar
(equipped with
fixture)
Nothing Insert 50 ohm
resister
For load state, use leaded 50 ohm standard (5012-
8846) equipped with E5061B-720
4. Connect DUT then scale measurement trace
a. Connect DUT to the xture
b. Press [Scale] then press Auto Scale All
5. Perform equivalent circuit analysis
a. Select equivalent circuit
Press [Analysis] then press Equivalent Circuit
Press Select circuit then press D
Press Display to turn on analysis
Press Calculate
Equivalent circuit is calculated
with the specied circuit model
and measured impedance value.
b. Perform simulation
Press [Analysis] then press Equivalent Circuit
Press Simulate
Press C1 then change value by [↑] or [↓]
Measured trace and
simulated trace can be
compared by changing
each component’s value.
Simulated trace is stored
in the Memory trace.
Which is the right circuit model for my DUT?
Models for equivalent circuit should be selected
depending on the type of the DUT.
A. Inductors with high core loss
B. Inductors with high winding resistance or
resistors with low resistance value
C. Resistors with high resistance value
D. Capacitors
E. Resistors
