11、 1/ A suitable gasket shall be bolted between the tube and the mounting seat. Tubes shall be supplied with gaskets at both ends. 2/ Preproduction sample approval requirements hereby replace any qualification requirements referable to the product covered herein. The term “First article testing“ shall

12、 be considered as synonymous with the term “Preproduction sample approval testing.“ All tests applicable herein (including all preproduction sample approval and conformance inspection, parts 1, 2, and 3) shall be performed during preproduction sample inspection. A failure of any one tube in any of t

13、he tests shall be cause for decision of preproduction sample disapproval. 3/ The tube shall be capable of being inserted and removed from its seat a minimum of 15 times with no deterioration in the tubes electrical characteristics. 4/ A swept frequency method may be used for this test. 5/ The TR tub

14、e will be terminated with a waveguide to type N transition (VSWR not to exceed 1.1:1 at test frequency) and a coaxial type N crystal mount connected to the transition. The mount will contain a type 1N21WE crystal which will be terminated by a dc ground return of 100 10 ohms. The crystal mount will h

15、ave a VSWR not to exceed 1.5 when tested with a microwave source at the test frequency which provides a crystal dc current between 0.3 ma to 1.5 ma in a 100 ohms termination. At the beginning of life test, the crystal noise figure (NF receiver) shall not exceed 7.0 dB under the standard 1N21WE test

16、conditions. The actual crystal noise figure at the beginning of life shall be recorded. 6/ The crystal noise figure degradation from the initial value shall not exceed 1.5 dB maximum. One crystal failure will be allowed during the life test. If a crystal failure occurs, a new crystal shall be insert

17、ed in the mount and the life test shall continue for a minimum of 100 hours.
