3、 interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for their particular need. The existence of such Publications shall not in any respect preclude any member or non-member of TIA from manufacturing or selling
4、products not conforming to such Publications. Neither shall the existence of such Documents preclude their voluntary use by non-TIA members, either domestically or internationally. TIA DOCUMENTS TIA Documents contain information deemed to be of technical value to the industry, and are published at t

Further details of the development process are available in the TIA Engineering Manual, loc
6、ated at http:/www.tiaonline.org/standards/sfg/engineering_manual.cfm TIA Documents shall be reviewed on a five year cycle by the formulating Committee and a decision made on whether to reaffirm, revise, withdraw, or proceed to develop an American National Standard on this subject.

This standard does not specify a specific naming convention for the filename portion of the filespec; ho
8、wever, those who generate filter characteristic data are encouraged to include some reference to the model number and to the date the data was taken. Because of compatibility issues, a filespec following the DOS 8.3 naming convention is encouraged, but is not required for compliance. 4.2 The File He
9、ader 4.2.1 General The file header consists of records that carry information not related to the devices characteristics data. 4.2.2 File Header Record Characteristics The header records to be used in digitized filter characteristics for the Terrestrial Land Mobile Radio Services are defined in Tabl
10、e 1. They are described in detail in the succeeding sub-clauses. Each header record begins with an abbreviated name field, ending in a colon. If one or more data field follows the abbreviated name field, there is no field delimiter between the abbreviated name field and the first field following it.
11、 If there are two or more data fields, the comma (“,”) serves as a field delimiter. All data positions up to and including the decimal point (if appropriate for the data type) shall be filled. Per-line comments may be added to any record. In any record, all data after a “!” character may be ignored.
12、 The record length, including the abbreviated record name but excluding the , shall not exceed the value specified in the Length column. If the format is free form, then the record may be shorter than the maximum length, and shall be terminated with a carriage return and line feed characters. Copyri

38、cteristics data follows the header data. Each data file includes at least one set of characteristics data. In cases where a given manufacturers model number corresponds to more than one characteristic curve (for example, in the case of different coupling loops), characteristics data will be presente
39、d corresponding to each different curve. Because filter power ratings are related to dissipation, the power ratings correspond to the coupling. Therefore, each set of data will include, in addition to the characteristic curves themselves, corresponding maximum average and peak power ratings. Within
40、the characteristic curves, the frequencies shall be absolute (not relative to center) and shall be expressed in MHz. 4.3.2 Data Header otherwise, optional. FR = Footer record.
