Thru Standard turn on S2 The Insertion Loss should be zero While still set up with the Thru Standard and S you can check the phase It should also read zero When done with the Calibration move the Transitions back to the Test Fixture Again do NOT remove the cables from the Transitions during this move or the cal will be inaccurate Make sure that the RF Pins are centered on the microstrip line and that there is enough pressure between the RF Pin and the substrate But use caution not to damage either of these parts Inter Continental Microwave 6501 W Frye Road Chandler AZ 85226 480 940 0740 fax 480 961 4754 www icmicrowave com sales icmicrowave com
3. c Component Size such as an 0805 follow installation below e Select and install the correct Midsection Assembly ex 0805 size After doing each of these steps you are ready to begin testing your components Choosing Midsection Assembly for Specific Component Size When testing a new specific component size you need to select the correct corresponding Midsection Assembly This insures that the component will make contact at the correct areas on the microstrip line and the ground pad If this is not accomplished you will have annomalies in your data due to incorrect spacing between the ground and RF signals on the device After you have selected the correct Midsection you need to disassemble the fixture and replace the Midsection Assembly that is currently in there There are 4 40 screws that hold the Midsection Assembly in place in the Test Fixture Simply remove the screws and take the Midsection Asembly off the fixture Take the Midsection Assembly currently in the fixture and place it in the provided case for safe keeping Align the new Midsection Assembly in the Test Fixture There is a red dot in one corner of the Midsection This corner goes toward the back left corner of the test fixture Losely tighten the screws on the bottom plate and make sure the dielectric pusher will make contact in the correct location on the substrate of the Midsection Once this is accomplished you can tighten the screws Testing Components Testing
4. components with this test fixture is a simple and straight forward manner After installing the correct Midsection Assembly on the fixture you are ready to test your components Simply place your component into the test fixture using the guides as alignment tools There should be very little slop in the placement of the device in order to insure accurate and repeatable testing After the device is properly seated in the fixture activate the press handle to move the dielectric pusher down onto the device This spring loaded pusher should come down and push onto the component to hold it in place with a consistent amount of pressure The device is now in place and ready for whatever electrical test you need to run When finished with the test raise the pusher up with the handle and remove the device and then repeat the above steps Calibration Procedure For Shunt Thru Test Fixture Using Series 2000 Calibration Kits The first step in Calibrating the Test Fixture is to remove the transitions from the Test Fixture For the Shunt Thru Test Fixture calibration there are no special steps from the normal Bolt On Transition Calibration Just follow the steps outlined below If you have any questions please contact ICM First you need to connect the cables from the Network Analyzer to the Transition Assemblies and install the Calibration Coefficients into the Analyzer After connecting the cables to the Transition Assemblies you do NOT want to una
