6、MDTNo reproduction or networking permitted without license from IHS -,-,- This Technical Report is one in a series produced by the InterNational Committee for Information Technology Standards (INCITS). The secretariat for INCITS is held by the Information Technology Industry Council (ITI), 1250 Eye
7、Street, NW, Suite 200, Washington, DC 20005. As a by-product of the standards development process and the resources of knowledge devoted to it, INCITS from time to time produces Technical Reports. Such Technical Reports are not standards, nor are they intended to be used as such. INCITS Technical Re
8、ports are produced in some cases to disseminate the technical and logical concepts reflected in standards already published or under development. In other cases, they derive from studies in areas where it is found premature to develop a standard due to a still changing technology, or inappropriate t
9、o develop a rigorous standard due to the existence of a number of viable options, the choice of which depends on the users particular requirements. These Technical Reports, thus, provide guidelines, the use of which can result in greater consistency and coherence of information processing systems. W
10、hen the draft Technical Report is completed, the Technical Committee approval process is the same as for a draft standard. Processing by INCITS is also similar to that for a draft standard. CAUTION: The developers of this technical report have requested that holders of patents that may be required f
11、or the implementation of the technical report, disclose such patents to the publisher. However, neither the developers nor the publisher have undertaken a patent search in order to identify which, if any, patents may apply to this technical report. As of the date of publication of this technical rep
12、ort, following calls for the identification of patents that may be required for the implementation of the technical report, notice of one or more claims has been received. By publication of this technical report, no position is taken with respect to the validity of this claim or of any rights in con
13、nection therewith. The known patent holder(s) has (have), however, filed a statement of willingness to grant a license under these rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to obtain such a license. Details may be obtained from the publisher. No further p

23、ds. This technical report describes the methods of characterizing a parallel SCSI domain by varying analog driver parameters and monitoring the results. The architecture for varying receiver parameters may be consistent with that used when varying analog driver parameters. The architecture for varyi
24、ng receiver parameters is not addressed in this technical report. This technical report addresses measuring the performance of driver-receiver connections. SCSI Parallel Interface-4 specifies minimum requirements of those connections. 2 References The following standards contain provisions that, thr
