To maintain adequate measurement performance, keep the electrodes and the short

plate in good condition. Contaminants and abrasion on these parts considerably affect

measurement results, especially for low value measurements. Periodic fixture cleaning

and part replacement is recommended to avoid deterioration of measurement perfor-

mance. The 16196x fixtures are designed with simplicity in mind, so that an operator

can easily replace parts. Spare parts, which are likely to be abraded, are supplied with

the 16196U Maintenance Kit.

16196U Maintenance kit

Opt. 16196U-010: Upper electrode, 5 piece set (common to 16196A/B/C models)

Opt. 16196U-300: Short plate for 0201 (inch)/0603 (mm) size, 5 piece set (for 16196C)

Opt. 16196U-310: Lower electrode, 5 piece set (for 16196C)

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. Next, open compensation is performed by placing

the furnished open plate on top of the insulator assembly. Short compensation is per-

formed by placing the furnished shorting plate on top of the insulator assembly. After

performing open and short compensations in combination with the electrical length

compensation, the DUT is inserted into the test fixture. Once the measurement of the

DUT is complete, remove the DUT from the fixture, by using the furnished push ring.

Refer to the 16196A figures to see how compensation and measurement is performed.

16196D Parallel electrode SMD

test fixture

Terminal connector: 7 mm

DUt connection: 2-Terminal

Electrical length: 27.3 mm

Dimensions (approx.):

140 (W) x 48 (H) x 78 (D) [mm]

Weight (approx.): 250 g

Additional error:

f: frequency [GHz]

Up to 3 GHz (7 mm): SMD continued

Description: This test fixture is designed for impedance evaluations of parallel electrode

SMDs. It achieves stable frequency characteristics up to 3 GHz and provides highly

repeatable measurements. The applicable SMD size code is 01005 (inch)/0402 (mm).

Applicable instrument: E4982A, E4990A + 42942A*, E4991B, E5061B-3L3/3L4/3L5

with Opt. 005 + 16201A

* Option E4990A-120 is required

Frequency: DC to 3 GHz

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

Operating temperature: –55 to +85 °C

DUT size: The applicable SMD size is 01005 (inch) /0402 (mm). For details, see the

figure below.

The 16196D is furnished with two different insulator assemblies, since any gaps

between the DUT and the cylindrical insulator will result in improper positioning and

subsequent measurement errors. Select an insulator assembly that reduces the gap the

most. See the table below for dimensions of the insulator assemblies.

Furnished accessories:

1. Opt. 16196D-710 only

2. 16196-15101 as replacement part number

Compensation and measurement: First of all, install the appropriate insulator as-

sembly into the fixture. Then, perform compensation. 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. Next, open compensation

is performed by placing the furnished open plate on top of the insulator assembly.

Short compensation is performed by placing the furnished shorting plate on top of the
