NEED FOR A RATING SYSTEM<\/u><\/p>\n
The conditions under which an electron tube may be operated are
\nlimited by fundamental capabilities of' the tube itself. Physical
\nlimitations exist, for example, in the permissible temperatures at
\nwhich the various electrodes may be operated, in the amount of
\ncurrent which can be emitted by the cathode, and in the voltage
\ngradients which may be permitted between the various tube
\nelements.<\/p>\n
Maximum tube ratings have been established to define these
\nvarious physical limitations of the tube in terms of readily
\nmeasurable quantities. The numerical quantities presented as
\nmaximum ratings indicate the limiting operating values required to
\nassure satisfactory tube life and performance.<\/p>\n
Before the value of any rating can become meaningful, the rating
\nsystem on which the rating is based must be spec\u00ecfied. The system
\nmust define the interpretation required of the numerical values and
\nindicate the procedure necessary to determine whether or not a tube
\nis operating within its rating.<\/p>\n
Until the present time, two rating systems have been commonly
\nused in conjunction with receiving tubes, the Design-Center System
\nand the Absolute-Maximum System.<\/p>\n
The problems created by their deficiencies have greatly
\nintensified in recent years primarily as a result of the greatly
\nincreased scope of receiving tube applications.<\/p>\n
To overcome the deficiencies encountered with the two rating
\nsystems in current use Maximum System" has been developed.<\/p>\n","protected":false},"excerpt":{"rendered":"
