4.1 Architecture overview
The term Receiver-Fixture Interface (RFI) describes the overall assembly that is used in electronic testapplications. Mounted to various ATS benchtop/portablce test system instrument configurations，(asdescribed by Figure l), the test interface provides a quick-disconnect mass termination betweenreceiver/fixture electrical units. The receiver is typically hard-mounted to the benchtop/portable chassis andserves as the receptacle part of the test interface，which can be scaled to the test requirement pinconfiguration. The fixture is uniquely designed for a specific test program set (TPS) to adapt a unit-under-test (uuT) to the ATS. In any application of the RFl, the architecture performs the same function ofquickly blind mating thousands of contacts and their related electrical signals with minimum effort andtime.
These signals are transferred within the receiver fixture interface by the connector contact pins or matinginterface points. To support and house the connector contact pins， a variety of receiver fixture contactmodules are employed in a pin configuration defined by the user application.
4.2 Framework specifications
The following subsections and illustrations describe the specifications for the framework configurationrequired to satisfy the scalable level of the application requirements. This information is stand-alone, butdoes reference the application IEEE Std 1505-2010 RFI Specifications, as part of IEEE Std 1505.3-2015.Rule 4.2.a: The configuration shall be implemented in intervals conforming to IEEE Std 1505-2010Framework Specification,Clause 5,that supports mounting of connector types in scalable frameworkintervals of four (4), nine(9),fourteen (14), and nineteen (19) slots (see Figure 3， Figure 4, Figure 5,Figure 6，and Figure 7). Every fifth slot shall be set aside as a blank slot to support side-by-side frameintegration and fixture engagement.
Rule 4.2.b: The framework shall be in accordance with the IEEE Std 1505-2010 Framework Specification,Clause 5， allow placement of any applicable fixture configuration (4/9/14/19 slot) to any matingconfiguration (4/9/14/19 slot) on the receiver (see Figure 7) by the implementer with proper frameworkkeying to validate proper location.
Rule 4.2.c: Physical footprint of the framework shall be in accordance with the IEEE Std 1505-2010Framework Specification, Clause 5, that limits dimensional envelope to a maximum 35.6 cm (14 inch) rackwidth, or height of 24.1 cm (9.5 inch) (including handle height).
Dual slot connector/contact configuration can be used as stand-alone or with the IEEE Std 1505-2010framework. When the scalable framework is applied, only the dual slot connector without shroud andjackscrew is used in the receiver/fixture. The two slot fixture connector can be separately mounted to amating configured receiver connector with shroudjackscrew mechanism. To broaden the pin configurationapplicability, the specification implemented a mixed contact configuration to support signal, power andcoax performance requirements in a dual slot connector housing. These contact types and quantities aredescribed and illustrated in Figure 8. This is a scalable design to delete/add connectors andor individualcontacts to minimize footprint, as well as repair/replace individual contacts to minimize maintenance of theconfiguration.
Rule 4.3.a: An implementation of IEEE Std 1505.3-2015 shall implement a compliant dual (two) slotmixed contact connector that is integrated into IEEE Std 1505-20i0 scalable framework design.Theconnector shall meet the IEEE Std 1505-2010 connector specifications for the specific signal, coax, andpower contacts and related mechanicalelectrical pin configuration described by the dual slot connectormodule, illustrated in Figure 8,Figure 9, and Figure 10.
Rule 4.3.b:Stand-alone dual slot connector module with shroud/jackscrew assembly shall be compliantwith the pin configuration described in Figure 8, when used in a panel mount scheme without an IEEE Std1505-2010 receiver framework.
