4.2.3 Measuring Impedance (Measurement Mode: IMPD
−3T)
The IMPD−3T measurement mode is a mode to attach a commercially available test fixture
used for an LCR meter or impedance analyzer to this instrument and then measure the
impedance characteristics of components.
Figure 4-4 Impedance Measurement Connection Example 4 (IMPD
−3T)
You can use a test fixture with an internal connection that is 4-terminal, 4-terminal-pair, or
2-terminal. For example, there are the
ZM2363 TEST FIXTURE
(for lead components) and
ZM2394H CHIP TEST FIXTURE
(for SMD). Other test fixtures are also available depending
on the purpose. For details, contact NF Corporation or its authorized agent.
Measurement in the IMPD−3T mode will be with a 3-terminal connection to the DUT even
when using a test fixture that is a 4-terminal or 4-terminal-pair. Therefore, measurements
will be affected by contact resistance and its variations. For low impedance measurements of
approximately 10 Ω or less, we recommend evaluating the measurement value variations due
to contact resistance using an actual DUT before use.
Set up this instrument and perform measurement in the following order.
1) Set the measurement mode to IMPD−3T in the
[Mode]
menu.
2) Reset the settings and then connect the test fixture and DUT.
3) Tap
[SETUP]
or press the
SETUP
key and then change each setting item as necessary.
[DISPLAY MODE Y]
: Set the graph Y-axis item.
[SWEEP ITEM]
: Set the sweep item.
[SWEEP UPPER]
: Set the sweep upper limit.
[SWEEP LOWER]
: Set the sweep lower limit.
4) Press the
AC/DC ON
key to turn measurement signal output on.
5) Press the
MEASURE DOWN
key to perform down-sweep measurement and then wait for
the sweep to end.
6) Operating the knob moves a marker on the measurement data. This allows you to read the
measurement value at any frequency. You can also perform operations such as detecting the
maximum value, searching, and finding the location of an arbitrary gain value. For more
details on the operations, refer to
“1.7 Marker Operations”
in
Instruction Manual (Advanced)
.
Performing open correction, short correction, and load correction enables measurement for
which the errors of the measurement system are corrected. For details on these correction
