SCOPE :This SAE Aerospace Standard (AS) contains a sample test plan for AS15531 or MIL-STD-1553B Remote Terminals (RT) that may serve several different purposes. This document is intended to be contractually binding when specifically called o

31、ut in a specification, Statement of Work (SOW), or when required by a Data Item Description (DID). Any and all contractor changes, alterations, or testing deviations to this section shall be separately listed for easy review.1.1 General:The purpose of these tests is to verify that the Unit Under Tes

32、t (UUT) responds properly in accordance with the requirements of the governing standard. The tests are not intended to verify the mission aspects stated in the equipment specification.The pass criteria is defined in each test paragraph. If any test fails, record the UUT response to that test.1.2 Fie

33、ld of Application:This general test plan is intended for design verification of remote terminals designed to meet the requirements of AS15531 and MIL-STD-1553B with Notice 2. Appendix A, B, and C provide cross references among this test plan, AS15531, and MIL-STD-1553B. For those remote terminals no

34、t required to meet Notice 2, Appendix D and E list the changes in this test plan for MIL-STD-1553B only and MIL-STD-1553B, Notice 1. The test plan requirements apply to the terminal under test, when invoked in a specification or statement of work.When invoked in a specification or statement of work,

35、 these requirements apply to the remote terminal and associated equipment which is developed either alone or as a portion of a system or subsystem development. The contractor is responsible for invoking all the applicable requirements of this document on any and all subcontractors he/she may employ.

DEFINITIONS:3.1 Responses:The following are definitions of the responses of the RT as used in this test plan. In e

40、ach case the status word must have the correct terminal address and unused status bits set to zero.3.1.1 Broadcast Command Received (BCR):The broadcast command received bit (bit time fifteen) is set in the status word (and no data words in response to a transmit status mode command or a single data

41、word in response to a transmit last command mode command).3.1.2 Clear Status (CS):The status word may have the busy bit and/or service request bit set. All other status code bits in the status word must be zero and the associated message must have the proper word count.3.1.3 Busy Bit (BUSY):CS with

42、the busy bit (bit time sixteen) set in the status word, and no data words.3.1.4 Dynamic Bus Acceptance Bit (DBA): CS with the dynamic bus control acceptance bit (bit time eighteen) set in the status word.3.1.5 Service Request Bit (SRB):CS with the service request bit (bit time eleven) set in the sta

43、tus word.3.1.6 Message Error Bit (ME):The message error bit (bit time nine) is set in the status word followed by no data words (except in response to a transmit last command mode command which requires one data word).3.1.7 No Response (NR):The addressed terminal does not produce any response to the

44、 command.3.1.8 Respond In Form:A terminal is said to “respond in form” if its response to an illegal command as defined in the paragraph titled “Illegal command” of AS15531 or MIL-STD-1553B consists of a response formatted as though it were a legal command.3.1.9 Subsystem Flag Bit (SF): CS with the

45、subsystem flag bit (bit time seventeen) set in the status word.3.1.10 Terminal Flag Bit (TF): CS with the terminal flag bit (bit time nineteen) set in the status word.Copyright SAE International Provided by IHS under license with SAENot for ResaleNo reproduction or networking permitted without licen

46、se from IHS-,-,-SAE AS4111- 8 -4. GENERAL REQUIREMENTS :4.1 General Test Requirements:The following paragraphs define the configurations, pass/fail criteria, and general procedures for testing remote terminals (RT). Specifically, this document contains the test configurations and procedures for the

47、Electrical Tests (5.1), the Protocol Tests (5.2), and the Noise Rejection Test (5.3) for AS15531 and MIL-STD-1553B remote terminals. The remote terminal under test is referred to as the Unit Under Test (UUT). Proper terminal responses are defined in each test paragraph. If the hardware/software desi

48、gn of the UUT does not permit a test to be performed, then adequate analysis shall be provided in place of the test results to demonstrate that the design meets the requirements of AS15531 or MIL-STD-1553B as stated in the test.Any condition which causes the UUT to respond other than as called out i

49、n AS15531 or MIL-STD-1553B, to lock up, or require a power cycle in order to recover for any reason shall automatically cause that UUT to fail the test. All occurrences of responses with the busy bit set in the status word shall be recorded. If the UUT response does not match the pass criteria for a particular test, then the UUT has failed that test.4.2 Test for Option
