INTRODUCTION

The Electrical Performance Standards for Direct View High Resolution Monochrome Closed Circuit Television Monitors given here represent, it is believed, the best agreement between the members of the Closed Circuit Television Committee, who drafted these Standards, consistent with the rapidly developing state-of-the-art.

Committee TR-17 has undertaken the development of Electrical Performance Standards for Direct View High Resolution Monochrome Closed Circuit Television Monitors to define significant parameters descriptive of operation of these devices and to outline minimum levels of performance deemed desirable to develop an acceptable display. This effort will promote interchangeability of the products of different manufacturers, thereby eliminating confusion on the level of performance that can be expected from an appropriately specified device. It will assist the purchaser in selecting and obtaining the proper product for a particular need. The lack of a previous standard for high resolution closed circuit television monitors justified this work.

The Standards consist of (1) Definitions, (2) Standards, and (3) Suggested Methods of Measurements, for those parameters believed to be of importance.

These Standards are intended to apply only to Direct View High Resolution Monochrome Closed Circuit Television Monitors with a video input; that is, signals generated at a nearby point where control can be exercised over picture quality. They are intended to apply with a video signal as described by EIA Standard RS-343A, "Electrical Performance Standards for High Resolution Monochrome Closed Circuit Television Camera," latest revision thereof.
