Mechanism for Connecting a DUT (Device Under Test)
The 16197A uses a device guide and an electrode plate for measuring to various sizes of bottom-electrode SMDs.
The electrode plate is placed onto the center electrode of the electrode unit, producing four different electrode spaces between the center electrode and electrode plate (Figure 2-2).
Figure 2-2 Structure of Electrode (1)
The device guide is placed on the electrode plate to enable each DUT to be positioned in a fixed location (Figure 2-3). Each DUT is set in a frame of the size suitable to the DUT for connecting to the electrode (Figure 2-4).
16 Keysight16197A Operation and Service Manual
Product Description Product Description
Figure 2-3 Structure of Electrode (2)
Figure 2-4 Connecting a DUT
The DUT is to be fixed under pressure from the pressure rod. Since the movable range of the pressure rod is limited, either one of the two lateral frames in the device guide can be used as the measuring position (Figure 2-5). Therefore, before connecting a DUT, it may be necessary to change the orientation of the electrode plate and device guide set in place so that the appropriate electrode and device guide frame arrive at the measuring position.

Determine the position of the frame to be prepared, keeping in mind the following requirements:
The electrode of the DUT must maintain equal contact with both the center electrode and electrode plate.
The electrode of the DUT must have a large contact area, and the electrode space between the center electrode and electrode plate must be as large as possible.
The pressure rod must be able to press the center of the DUT to stabilize the DUT during measurement.

Operation Performing Fixture Compensation
Performing Fixture Compensation
To ensure accurate measurement, it is necessary to perform fixture compensation before measurement. For the 16197A, measure the SHORT compensation and OPEN compensation data. If the DUT size or the measuring position is changed, perform fixture compensation again.
If a temperature change greater than ± 5°C occurs after fixture compensation, perform the fixture compensation from the beginning.
Measuring the SHORT Compensation Data
With the fixture SHORT state using a supplied shorting bar, measure the SHORT compensation data.
Step 1. Rotate the pressure adjusting nut to adjust the pressure on the pressure rod
to the same value as used for measurement.
Step 2. Loosen the knobs on the sliding block, and adjust the position of the pressure
unit so that the end of the pressure rod is located at the center of the device guide frame where the shorting bar will be placed (Figure 3-13).

Step 3. Press the lever to the limit (Figure 3-14,1). With the lever pressed, push in the
latch (Figure 3-14,2), and then release the lever (Figure 3-14,3). The pressure rod is then fixed at its raised position.

Connecting and Measuring the DUT
Connect the DUT with the electrode, and carry out the measurement.
Step 1. Place the DUT on the electrode in an appropriate device guide frame (Figure

Step 2. Press the lever to disengage the latch (Figure 3-19,2), and slowly release the
lever to lower the pressure rod (Figure 3-19,3).
Figure 3-19 Connecting the DUT
Step 3. Perform the measurement according to the operation manual for the
measuring instrument to be used.
The DUT may become hot during measurement. If the temperature of the DUT rises, the end of the pressure rod may be deformed. If this occurs, decrease the pressure on the pressure rod to prevent deformation of the end of the rod.
To ensure accurate and repeatable measurements, place the DUT alongside a fixed edge of each device guide frame. Testing a 3216 DUT, for instance, uses the 3216/3225 frame. Since this frame is dimensioned to fit with a 3225 device, some clearance remains in the frame if it is used for a 3216 DUT. Therefore, it is necessary to place the DUT alongside a fixed edge of the frame.

4 User Maintenance
This chapter describes the operations to perform before starting measurement, and the procedures necessary to ensure accurate measurements.
Description
Necessity of User Maintenance
Through repeated use, the fixture's measuring performance will gradually deteriorate over time due to smearing on the contact faces from solder buildup, and to mechanical wear and deformation of the contact faces themselves. To continually achieve optimal measurement results, it is important to keep the contact faces in good condition and take appropriate action before such wear or deformation occurs. Therefore, the fixture should be properly cared for by implementing each of the maintenance items shown in
Table 4-1.

Maintenance of the fixture is important especially to ensure fine or highly accurate measurement, since deteriorated measurement performance of the fixture has a significant effect on the measurement results. Depending on the required measurement performance, it may be necessary to increase the frequency of maintenance and/or adopt more strict criteria for each maintenance item.
The electrodes and shorting bars are consumable. Of all the fixture components, these parts are most likely to affect the measurement results. The electrodes tend to deteriorate gradually since they can easily be smeared with solder transferred from the DUT during measurements. Because shorting bars are used to determine the zero reference for fixture compensation, smeared or deformed shorting bars can directly influence measurement results. This chapter describes the general user maintenance requirements, focusing primarily on the electrodes and shorting bars.

Deterioration Check
Deterioration Check
A deterioration check must be performed to determine the state of deterioration of the fixture and to confirm whether the fixture is providing the required measurement accuracy. The deterioration check comprises three operations: “Setting user limit values,” “Acquiring Reference Values”“Electrode
Deterioration Check”. In the deterioration check, the impedance values (Rs, Ls)
of the fixture itself are measured at a discretionary frequency. It is recommended to use the frequency at which the fixture is normally used.
Perform “Setting user limit values” in the following cases:
— When using the fixture for the first time after delivery
— When changing the required measurement accuracy
Perform “Acquiring Reference Values” in the following cases:
— When using the fixture for the first time after delivery
— After replacing parts
Perform “Electrode Deterioration Check” in the following cases:
— Once a day, and before conducting fixture compensation
Example Settings of User Limit Values
User limit values for the deterioration check should be set appropriately according to the type of DUT, required measurement accuracy, and so on. Example settings of user limit values are shown below.
To evaluate an inductor (L:10nH, Q:10) at a frequency (f) of 100 MHz with a measurement accuracy of around 20%:
L: 10nH
Q: 10
Frequency: 100MHz
Required measurement accuracy: 20% for both L and Q
The reactance X and resistance R of the inductor under the above-mentioned conditions can be obtained as follows:
Keysight16197A Operation and Service Manual 47
4-
QXR 2fLR==
User Maintenance Deterioration Check
Therefore, . Accordingly, if R fluctuates by 20% (120 m), Q will change by about 20%; and if L fluctuates by 20% (2 nH), both L and Q will change by about 20%. In other words, to measure L and Q at an accuracy of 20% or less error, errors in L and R must be 2 nH and 120 m
at the most,
respectively. Considering that both L and R may fluctuate, and allowing for possible causes of error other than a deteriorated fixture, the errors must be set smaller than the above-mentioned values. For the present example, with the error set at 25% for both L and R, the user limit values for L and R are set at 500 pH and 30 m, respectively.
Note that the above settings are just an example. Actually, user limit values should be varied depending on the measuring conditions and type of DUT.
In actual measurement, some of the effect of electrode deterioration is canceled by SHORT compensation. However, it is recommended to set user limit values on the assumption that deviations from the reference values affect the entire measurement results, as shown in the above example.
Necessary equipment
Record the user limit values in the “Check Sheet” on page 51. For the method of recording, see “Example Entry in Check Sheet” on page 51.
Acquiring Reference Values
To obtain reference values, measure the impedance (Rs, Ls) of the fixture before deterioration. It is recommended to take measurements at a frequency at which the fixture is normally used. It is necessary to obtain reference values using electrodes and shorting bars for all sizes of DUTs that will be subject to actual measurement.
“Acquiring reference values” is necessary in the following cases:
— When using the fixture for the first time after delivery
— After replacement of parts
— Shorting bars (supplied as accessories)
— Impedance measuring instrument (calibrated at the 7mm connector end)
Set the fixture compensation for the measuring instrument to OFF.
Check that each shorting bar is not deformed or stained.

User Maintenance Deterioration Check
Procedure for Acquiring Reference Values for the Electrode Deterioration Check
Step 1. Clean each electrode and shorting bar using the method described in
“Cleaning” on page 45.
Step 2. At the actual DUT measurement position, connect an appropriate shorting bar
with the electrode to set the fixture for the SHORT state (See Figure 3-16 on
page 37).
Step 3. Measure Rs and Ls according to the Operation and Service Manual for the
measuring instrument.
Step 4. Record the Rs and Ls readings as reference values in the “Check Sheet” on
page 51
Step 5. From the reference values and the user limit values determined in the
preceding section, calculate the upper and lower limit values, and record them in the Check Sheet.
Electrode Deterioration Check
Measure the impedance of the fixture in the SHORT state to check for electrode deterioration. Use a shorting bar suited to the size of the actual DUT.
Necessary equipment
The electrode deterioration check is necessary in the following cases:
— Once a day, and before conducting fixture compensation
— Shorting bars (supplied as accessories)
— Impedance measuring instrument (calibrated at the 7-mm connector end)
Set the fixture compensation of the measuring instrument to OFF. Set all other functions to the same states according to “Acquiring Reference
Values”
Electrode Deterioration Check Procedure
Step 1. Clean each electrode and shoring bar using the method described in
“Cleaning” on page 45.
Step 2. Perform the measurement, with the measuring instrument set for the same
conditions as mentioned in “Procedure for Acquiring Reference Values for the
Electrode Deterioration Check” on page 49.
Step 3. Record the Rs and Ls readings, as well as their acceptability, in the “Check
Sheet” on page 51.

Specifications and Supplemental Performance Characteristics Residual Inductance of the Shorting Bar
Residual Inductance of the Shorting Bar
The usual method to compensate the test fixture's residual inductance is to let SHORT = 0H. In this method, the measurement result is the relative value of the measured impedance to the shorting bar's impedance. The short bar's residual inductance as a result of its size and shape is not estimated.
On the other hand, there is a definition method to let SHORT = x H. In this method, the measurement result is the absolute value of the device's impedance. The short bar's residual inductance as a result of its size and shape is estimated under specific conditions and is used as a reference value. This method, is useful for devices with values which are close to the short conditions of the measurement system.
The reference inductance values presented Table 5-1 were simulated as the relative difference to a disk-type 0 W termination on either the 7mm or the
3.5mm connector. The measurement of these short bars under other
conditions than shown below cannot reproduce the reference inductance values.

Service Changing the Orientation of or Replacing the Contact Assembly
Changing the Orientation of or Replacing the Contact Assembly
If the center electrode of the contact assembly is smeared, an unused clean area of the center electrode can be used simply by changing the orientation of the contact assembly. This section describes the method for changing the orientation of or replacing the contact assembly.
To change the contact assembly orientation or replace the contact assembly, it is necessary to use a 1.5-mm Allen wrench (Keysight part number: 8710-0909) and a Phillips screwdriver.
Procedure for Changing the Orientation of or Replacing the Contact Assembly
1. Take off the guide holder, and remove the device guide and electrode plate. (See to Figure 3-4 on page 28).
2. Remove the four screws from the upper side of the fixture, and then remove the contact assembly and flange.

Operation Check
This section describes the operation check method. Be sure to perform the operation check after each time a part is replaced.
Open Impedance Check
Conduct an Open impedance check with the fixture set for the OPEN state.
Necessary equipment
— Shorting bars (supplied as accessories)
— Impedance measuring instrument (calibrated at the 7-mm connector end)
If a measuring instrument other than the 4291B is to be used, make the equivalent settings according to the Operation and Service Manual for the instrument to be used.
Step 1. Prepare a measuring instrument calibrated at the 7-mm connector end.
Connect the test fixture with this instrument.
Step 2. Set the fixture for the OPEN state, at the DUT measuring position (see Figure
3-18 on page 38).
Step 3. Make the settings for the 4291B as follows.
