Overview

The Option S96041B Impedance Measurement application measures the impedance parameter up to 10 GHz with E5080B.

The following calibration kit and test fixture are required to make a measurement.

• 85052DH02 Economy Mechanical Calibration Kit (85052DH02 is different from 85052D. The calibration data file for each unit is provided.)

• 16198A Bottom Electrode SMD Test Fixture (Option 010 only)

Note: E5080B over 20 GHz models are not supported.

Measurement Preparation

This section shows you the required preparation before you make an measurement.

1. Prepare the following items

• 85052DH02

• Open (female), Short (female), Load (female)

• Calibration data file: This file is provided by USB memory furnished with the product.

• 16198A Option 010 (See the 16198A user's guide in https://www.keysight.com/manuals/16198a for details)

• Fixture with a contact board and weight.

• Adapter Box

• Semi-rigid cable between Adapter Box and VNA

• Short bar

• Calibration Data (See the next step)

• Torque wrenches

2. Get the calibration data file of 16198A

• Each unit of 16198A Option 010 is calibrated at the factory and its calibration data is provided though Keysight support website.

1. Visit https://support.keysight.com/. Click Calibration Certificate in SERVICES.

2. Enter 16198A as the product number and your serial number. The serial number label is placed on the right side of fixture main unit. The serial number is 10 digit number beginning with MY or SG.(Do not use the number beginning with 1B)

3. Select SERVICE STATUS / CAL DOCS tab.

4. Confirm the certificate number starts with FACT-KEYS-1Bxxxxxxxxx. The 10 digit number beginning with 1B is the manufacturing ID. Confirm if this number is matched with the number labeled on the left side of fixture main unit.
   

5. If the manufacturing ID number is NOT matched with the number labeled on the left side of fixure main unit, visit Support top page again and enter manufacturing ID number instead of the serial number.
   Note: If your unit is repaired, the serial number is kept but the manufacturing number is changed if the calibration data is updated.

6. Click the Characterization Data under Service Documents.

7. The calibration data is stored as ZIP file. Download and extract it. The file extension is ".dat".

8. Move the .dat file into E5080B.

3. Place the Adapter box in front of  the E5080B and connect it with the E5080B through the Semi-Rigid cable. The tightening torque used is 0.9 Nm for 3.5 mm and 1.36 Nm for Type N

Wear Check Procedure

The wear check allows you to obtain an idea about the deterioration of the fixture in order to ensure that the desired measurement accuracy is obtained.

Refer to the 16198A Users Guide for the test limit.

For open state setup

1. Preset

2. Click Meas > S-Param > Sxx (S22, S33 or S44) if the adapter box is connected with other than port 1.

3. Click Freq > Main > Start, Stop and set start and stop frequencies at 1 GHz and 3 GHz respectively.

4. Click Power > Main > Power Level and set the power level at -16 dBm.

5. Click Cal > Other Cals > Basic Cal.

• Connector: 3.5 mm

• Cal Kit: your 85052DH02 calkit.

• VNA Port: Check only the port where the adapter box is connected.

• DUT: Female

• Cal Type:OSL

6. Click Next, then execute Open/Short/Load calibrations.

7. Click Finish.

8. Click Math > Analysis > Conversions > Y-Reflect.

9. Click Format > Format 2 > Real.

10. Take measurements of the data for the open state.

11. Click Marker > Marker 1 and 2, then move the markers at 1 GHz and 3 GHz.

12. Compare the result with the limit.

For short state setup

1. Setup and Calibration is the same as the open state

2. Click Math > Analysis > Conversions > Z-Reflect.

3. Click Format > Format 2 > Real.

4. Set the 200 to 300 g weight.

5. Place a short bar at the right position on the contact board.

6. Set the fixture in the short state

7. Make sure if the pusher pushes the short bar properly

8. Take measurements of the data for short bar.

9. Click Marker > Marker 1 and 2, then move the markers at 1 GHz and 3 GHz.

10. Compare the result with the limit.
