Exchanging the device holder

1. Remove the ground plate

2. When measuring SMD, attach the

knob on the device holder.

3. Select the device holder suitable for

the device type. Loosen its knob and

insert into the arm.

4. Set the ground plate.

Placing the device

Options:

16194A-010: Add EIA/EIAJ industrial standard sizedshorting bar set

16194A-701: Add general sized shorting bar set

Compensation and measurement: Before beginning the measurement, the appropriate

device holder (for a SMD or lead component) must be prepared with the text fixture. The

following figure shows how the device holder is exchanged to match the device type.

The next step is to perform open and short compensations in combination with the

electrical length compensation. When measuring above 500 MHz, load compensation

is also recommended. The fixture’s electrical length must be entered into the electrical

length compensation function of the measurement instrument first. Then open com-

pensation 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 using the option 16194A-010/701 shorting bar set. Load compensation is

performed by using the furnished 50 Ω SMD chip resistor. After performing open, short,

and load compensations in combination with the electrical length compensation, the

DUT is inserted into the test fixture. The following figures show how measurement is

performed.

Fixture overview

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 0603 (inch)/1608 (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 0603 (inch)/1608 (mm). For details, see the figure

below.

The 16196A is furnished with three 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.

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-100: Short plate for 0603 (inch)/1608 (mm) size, 5 piece set (for 16196A)

Opt. 16196U-110: Lower electrode, 5 piece set (for 16196A)

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

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. The following figures show how compensation and measurement is

performed.
