Terminators Connectorized with D-6025 Connector
Interface
D-6021
Revision A1
25-Mar-15
f. Connectors--Per Raychem Specification D-6025 and the applicable
specification control drawing.
3.5 Design and Construction Requirements
These items are designed to be nonrepairable components which are connectorized for
inclusion in data bus harnesses. They shall consist of encapsulated electrical components
within an EMI shielded housing. Box couplers consist of encapsulated transformer/resistor
modules, and terminators consist of encapsulated resistors.
3.5.1 Weight, Configuration and Dimensions
Weight, configuration and dimensions of couplers and terminators shall be as
shown in the applicable specification control drawings.
3.5.2 Interchangeability
All items having the same part number shall be completely interchangeable with
each other in regard to installation and performance.
3.6 Performance Requirements
When tested in accordance with the procedures defined in 4.5, couplers and terminators
shall conform to the requirements specified herein and in the applicable specification
control drawing. Tests marked with an asterisk (*) are not applicable to general, purpose
terminators (see 1.3).
3.6.1 Functional Tests
3.6.1.1 Transformer/Resistor Module Requirements. Transformer/resistor
modules and their component elements shall meet the requirements of
MIL-STD- 1553B.
3.6.1.2 Box Coupler Input Impedance. When box couplers are tested as specified
in 4.5.3.1, the input impedance shall be 3000 -* (number of stubs) ohms,
minimum over the temperature range specified.
3.6.1.3 Box Coupler Waveform Integrity Test
When single stub box couplers are tested as specified in 4.5.3.2, the drop
of the waveform on the bus leads shall not exceed 20 percent. Overshoot
and ringing shall be less than ± 1.0 volt peak.
3.6.1.4 Box Coupler Maximum Voltage Test
When a box coupler is tested as specified in 4.5.3.3, the voltage on the
coupler's bus cables shall be between 8 and 10 V p-p.
3.6.1.5 Box Coupler Minimum Voltage Test
When a box coupler is tested as specified in 4.5.3.4, the voltage on the
coupler's bus cables shall be between 5 and 7 V p-p.
