SCOPE:This test plan is broken into three major sections for the testing of bus controllers Electrical, Protocol and Noise tests.1.1
26、General: This validation test plan defines the test requirements for verifying that the design of bus controllers meets the requirements of MIL-STD-1553B, “Digital Time Division Command/ResponseMultiplex Data Bus.“1.2 Application: This is a general test plan for any first article, prototype, or engi
27、neering preproduction bus controller designed to meet the requirements of MIL-STD-1553B. These requirements shall apply to the bus controller under test, when invoked in a specification or statement of work.This document deals only with bus controller functions that are explicitly described in MIL-S
28、TD-1553B. This document does not specify tests that check the integrity of data from the subsystem to the bus, nor does it attempt to address the system test requirements.2. APPLICABLE DOCUMENTS:2.1 Standards. Military:MIL-STD-1553B, 21 Sep 1978 “Aircraft Internal Time Division Command/ResponseMulti
29、plex Data Bus“ with Notice 2, 8 September 1986.3. DEFINITIONS:3.1 Message: A single message is the transmission of a command word, status word, and data words if they are specified. For the case of a remote terminal to remote terminal (RT to RT) transmission, the message shall include the two comman
30、d words, the two status words, and data words. All messages are divided into two message segments: a command message segment and a status message segment.3.1.1 CMS - Command Message Segment: A command message segment consists of a command word and associated data words, if any. In the case of RT to
31、RT transfer, the command message segment includes both the receive command word and the transmit command word.3.1.2 SMS - Status Message Segment: A status message segment consists of a status word and associated data words, if any. In the case of RT to RT transfer, the status message segment include
32、s the status word of the transmitting RT, its associated data words, and the status word of the receiving RT.3.2 Bus Conditions: The following are definitions of bus conditions that bus controllers are required to detect. A description of the actual signal, state, or action taken within the bus cont
33、roller, which is used during test procedures to indicate the detection of each of the following bus conditions, shall be attached to the test results. Bus controller states may or may not be distinguishable; that is, a single bus controller signal may indicate both NR and ISMS.Copyright SAE Internat
34、ional Provided by IHS under license with SAENot for ResaleNo reproduction or networking permitted without license from IHS-,-,-AS4113Page 63.2.1 VSMS - Valid Status Message Segment: A VSMS condition occurs within a bus controller when if determines that a SMS contains only a CS and valid data words,
35、 the data words are contiguous to the status word and each other, and the response time is as specified in MIL-STD-1553. 3.2.2 ISMS - Invalid Status Message Segment: An ISMS condition occurs within a bus controller when it determines that a SMS is not a VSMS.3.2.3 NR - No Response: A no response con
36、dition occurs if a bus controller determines that there has been no response to a command.3.2.4 CS -Clear Status: The status word ma have the busy bit or service request bit set, or both. The status word must have the correct terminal address, all other status code bits in the status word must be ze
37、ro and the associated message segment must have the proper word count.3.3 Other Definitions:3.3.1 VW - Valid Word: A valid word conforms to the following minimum criteria:a. The word begins with a valid sync field.b. The bits are in a valid Manchester II code.c. The information field has 16 bits plu
38、s parity.d. The word parity is odd.3.3.2 UUT - Unit Under Test: For the purposes of this test plan, UUT refers to the bus controller under test.3.3.3 BC - Bus Controller:3.3.4 RT - Remote Terminal:3.3.5 MCX - Mode Code: For the purposes of this test plan, mode codes are tabulated in Table 1.3.3.6 DB
39、ACC - Dynamic Bus Control Acceptance Bit: The status word bit at bit time 18.4. GENERAL TEST REQUIREMENTS:The following paragraphs define the configurations, pass/fail criteria, and general procedures for testing bus controllers. Specifically, this document contains the test configurations and proce
40、dures for the Electrical Tests (5.1), the Protocol Tests (5.2), and the Noise Rejection Test (5.3) for MIL-STD-1553 bus controllers. Bus controllers that can be deployed in more than one configuration, depending upon the choice of stored program or hardware option, shall be tested using all specifie
41、d configurations such that the test program exercises all of the bus controllers capabilities. Before performing each test, the UUT shall be cleared of any preexisting error conditions to Insure that all test results are independent of previous results.Copyright SAE International Provided by IHS und
42、er license with SAENot for ResaleNo reproduction or networking permitted without license from IHS-,-,-AS4113Page 74.1 General Monitoring Requirements: In addition to the specific tests that follow, certain parameters of the BC transmission must be continuously monitored throughout all tests. These p
43、arameters are:1. contiguous data2. proper Manchester encoding3. proper bit count4. odd parity5. proper word count6. proper intermessage gap times7. proper sync8. proper CMS transmissionThis general monitoring requirement shall include the verification that the CMS transmitted by the UUT is the CMS s
44、pecified to be transmitted by the procedure.The UUT shall have failed the test if, at any time during the test, any of these parameters fall to meet therequirements of MIL-STD-1553. Record the parameters for all failures.5. DETAILED REQUIREMENTS:5.1 Electrical Tests: All tests shall use Fig. 1, Gene
45、ral Test Configuration, with all measurements taken at point “A“, unless otherwise noted. Each test paragraph contains the requirements for both transformer and direct coupled stubs. A UUT which provides both transformer and direct coupled stubs must be tested on both stubs. Electrical tests shall b
46、e performed on all buses for UUTs with redundant bus configurations.5.1.1 Output Characteristics: The following tests are designed to verify that all UUT output characteristics comply with MIL-STD-1553.5.1.1.1 Amplitude: A receive command shall be transmitted by the UUT, with the maximum number of w
47、ords that it is capable of sending. The amplitude of the waveform transmitted by the UUT shall be measured, peak-to-peak, as shown in Fig. 2.The pass criterion for Vpp for transformer coupled stubs is 18.0 V minimum and 27.0 V maximum.The pass criteria for Vpp for direct coupled stubs are 6.0 V mini
48、mum and 9.0 V maximum.Copyright SAE International Provided by IHS under license with SAENot for ResaleNo reproduction or networking permitted without license from IHS-,-,-AS4113Page 85.1.1.2 Rise Time/Fall Time: A receive command shall be sent by the UUT with at least one data word. The rise and fal
49、l time of the UUT waveform shall be measured between the 10 and 90% points of the waveform as shown in Fig. 2. The measurements shall be taken at both the rising and falling edges of a sync waveform and a data bit waveform. The rise time (TR) and the fall time (TF) shall be measured. The pass criteria are 100 ns = 1000 for transformer coupled stubs and Zin =
