Up to 120 MHz (4-Terminal Pair): Material continued

Compensation and measurement: Short compensation is recommended

in combination with the cable length compensation before measurement.

First, set the instrument’s cable length compensation function to 1 m. Then,

short compensation is performed by using the furnished shorting plate. Open

compensation is not performed, but its values are used in the dielectric constant

equation as shown below:

)

Co ω CoRp

α : Correction coefficient

: Relative dielectric constant

Cp : Liquid capacitance (measurement data)

Co : Air capacitance (measurement data) or open compensation data

Rp : Equivalent parallel resistance (measurement data)

ω : Angular frequency (ω= 2πf)

The following figures below show how compensation and measurement is

performed.

Note: The 16452A is not capable of measuring salt or ionic solutions or other

liquids with bulk conductivity due to the electrode polarization phenomenon.

Keysight is not responsible for any damage (e.g., corrosion, smear) to the 16452A

caused by the reaction between the liquid under test and the 16452A.

Description: This test fixture is designed for impedance evaluation of both lead

and SMD. It is furnished with two modules that can be readily screwed onto the

plate to measure either lead or SMD.

Applicable instrument: E4982A, E4990A + 42942A*, E4991B,

E5061B-3L3/3L4/3L5 with Opt. 005 + 16201A

* Option E4990A-120 is required

Frequency: DC to 500 MHz

Maximum voltage: ±42 V peak max. (AC+DC)

Operating temperature: 0 to 55°C

DUT size: See figure below

Furnished accessories:

Compensation and measurement: Open and short compensations are

recommended in combination with the electrical length compensation before

measurement. The fixture’s electrical length must be entered into the electrical

length compensation function of the measurement instrument first. When using

the SMD module, open compensation is performed by separating the high and

the low electrodes from each other. The separation should be equivalent in size

to the DUT’s width. Short compensation is performed by usinf the furnished

shorting plate. When using the lead component module, open compensation

is performed by not having the module-electrodes be connected to anything.

Short compensation is performed by using the furnished shorting plate. After

performing open and short compensations in combination with the electrical

length compensation, the DUT is inserted into the test fixture.
