Note 1 : Absolute rating should not be exceeded under continuous or transient conditions. A single absolute

rating may be the limitation and simultaneous operation at more than one absolute rating may not be

possible. Equipment design should limit voltage and environmental variations so that ratings will be

exceeded.

Note 2 : The Klystron body should be at ground potential in operation.

Note 3 : All voltages are referred to the cathode potential except the heater voltage.

Note 4 : The optimum operating value is shown on a test performance sheet for each tube.

Note 5 : Characteristics and operating values on this Data Sheet are based on performance test. These values

may be changed as a result of additional information or product improvement. NEC should be con-

sulted before using this information for equipment design. This data sheet should not be referred to a

contractual specification.
