16453A Dielectric Material Test
Fixture
Terminal Connector: 7 mm
Dimensions (approx.): 130(H) x 50(W) x 60(D) [mm]
Weight (approx.): 600 g
Measurement Accuracy (including the E4991A):
Up to 3 GHz (7 mm) Material
Description: The 16453A is designed for accurate dielec-
tric constant and loss tangent measurements on the
E4991A. It employs the parallel plate method, which
sandwiches the material between two electrodes to form a
capacitor. E4991A measures the capacitance created
from the fixture, and option E4991A-002 firmware calcu-
lates the relative complex permittivity as described in the
16451B. Adjustment to insure parallel electrodes is
required when using the 16451B. This adjustment is not
required with 16453A because the fixture has a flexible
electrode that adjusts automatically to the material sur-
face.
Applicable Instruments: (E4991A with Opt. E4991A-
002, 4291B with Opt. 4291B-002*)**
* denotes the instrument is obsolete.
** applicable in a limited frequency range.
Frequency: 1 MHz to 1 GHz
Maximum DC Bias Voltage: ±40 V
Operating Temperature: -55°C to 200°C
When Option E4991A-007 temperature characteristic test
kit is used with E4991A, the operating temperature range
is between -55°C and +150°C.

Compensation and Measurement: Open, short and
load compensations are recommended before measure-
ment. Open compensation is performed by separating the
high and the low electrodes from each other. Short com-
pensation is performed by connecting the high and low
electrodes together. Load compensation is performed by
using the furnished load material. After performing open,
short and load compensations, the material under test is
inserted into the test fixture.
