21、00:1992 BSI 10-1999 iii Foreword The CENELEC Electronic Components Committee (CECC) is composed of those member countries of the European Committee for Electrotechnical Standardization (CENELEC) who wish to take part in a harmonized System for electronic components of assessed quality. The object of
22、 the System is to facilitate international trade by the harmonization of the specifications and quality assessment procedures for electronic components, and by the grant of an internationally recognized Mark, or Certificate, of Conformity. The components produced under the System are thereby accepte
23、d by all member countries without further testing. This specification has been formally approved by the CECC, and has been prepared for those countries taking part in the System who wish to issue national harmonized specifications for DISPLAY STORAGE TUBES. It should be read in conjunction with docu
24、ment CECC00100: Basic Rules(1974). At the date of printing of this document the member countries of the CECC are Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, theNetherlands, Norway, Portugal, Spain, Sweden, Switzerland, and the UnitedKingdom. Copies of it can be obtained from
25、 the addressees shown on the blue fly-sheet. Preface This specification was prepared by CECC Working Group11: Electro-optical devices. In accordance with the requirements of document CECC00100 it is based, wherever possible, on the Recommendations of the International Electrotechnical Commission. It
26、 is a sectional specification for display storage tubes relating to the generic specification CECC11000. The text of this specification was circulated to the CECC for voting in the document indicated below and was ratified by the President of the CECC for printing as a CECC Specification: This speci
27、fication will be supplemented by blank detail specifications applicable to each sub-family of display storage tubes. The CECC Management Committee at its meeting in Copenhagen in March1979 decided that as the German National Authorized Institution would not be implementing the requirements of this C
28、ECC sectional specification, the text should be published in the English and French versions only.

46、rmity of pulse erasure (in a specified period) over the useful screen area at a specified screen voltage. NOTE 1This test is not suitable for bistable tubes. Procedure Apply electrode voltages as prescribed in the detail specification. The write gun(s) modulator electrode(s) shall be biased beyond c
47、ut-off. Deflecting fields may be applied to protect the tube in the event of flashover. Allow the specified warm up period. Adjust the pulse duration so that the screen area is darkened in approximately 50% of the specified period from the application of the erasure pulses. The clearance procedure s
48、hall be carried out before checking the effect of an adjustment to the pulse duration. Adjust the voltages applied to the flood gun modulating and other specified electrodes to achieve the specified maximum uniformity of erasure (seeNote2) over the useful screen area. The clearance procedure shall b

NOTE 2Uniformity of erasure is 1) determined by maintaining the erasure pulse amplitude and repetition frequency as used above, and adjusting the pulse duration to achieve complete darkness in the specified period, for example10s; 2) defined by: Conditions to be prescribed in the detail specification Electrode voltages, as appropriate The screen voltage if applied during clearan
