17、ontinued. 1/ This specification sheet uses accept on zero defect sampling in accordance with MIL-PRF-1, table III. 2/ If these tests have previously been performed by the tube manufacturer, and if the materials, manufacturing processes, and test requirements are the same as when the tests were perfo

18、rmed, the subject test (or tests) need not be performed. 3/ The tube heater shall be protected against arcing by the use of a connector that places a minimum capacitance of 4,000 pF across the heater directly at the input terminals. 4/ In handling and mounting the tube, care shall be exercised to pr

19、event demagnetization. Ferromagnetic material shall not be brought within 12 inches of the tube; energized magnets shall not be brought within 18 inches of the tube. 5/ Reasonable care shall be used in transportation, storage, installation, and use of the tube to avoid imparting vibration or shock i

20、n excess of the values which the tube is designed to withstand. 6/ The tuner dial settings referable to corresponding frequency values shall be marked on each tube, in successive 100 MHz steps of frequency. Calibration of the tuner dial shall be effected under conditions of T(anode) = +100C (approxi

21、mate). 7/ The starting stability test shall be performed on 100 percent of the submitted lot. 8/ Measurement shall be made at the “hot test“ frequency setting corresponding to 9,600 MHz (operational frequency), and shall be made using “cold test“ techniques. The g limits specified apply to the fract

22、ion of wavelength determinable as the test goal. 9/ One cycle shall consist of a complete traverse from one end of the tuning range to the other end, and back again. 10/ Separate samples shall be used for this test. 11/ A modulator of the discharging-network type shall be used for test(s). 12/ The s

23、tanding-wave introducer shall be moved continuously, during the test, so that operation is obtained for all phases of VSWR. The standing-wave introducer shall be cycled continuously through a one-half wavelength of transmission line at a maximum rate of 4-cycles per hour. 13/ The characteristics of

24、the applied pulse shall be those which result in proper starting and oscillation. The rate of pulse voltage rise, the percentage of pulse voltage ripple, and the rate of pulse voltage fall are important considerations. Fall time of the current pulse shall not exceed 0.12 s. No spike or ripple shall

25、exceed 7.0 percent of average peak of pulse current. Inverse voltage shall not exceed 30 percent of the forward voltage. There shall be no negative post-pulse voltage oscillations since they may result in leakage current and noise. 14/ The tube shall be operated into a transmission line having a min

26、imum VSWR of 1.5:1 adjusted in phase to produce maximum spectrum degradation. 15/ The RF bandwidth shall be within the limits specified when a VSWR of 1.5:1 is introduced in the load at approximately 0.6 meters distance from the tube coupling flange, with the phase adjusted for widest spectrum. 16/

27、With the VSWR adjusted to that phase producing maximum instability, the missing pulses shall be counted during the last 3 minutes of a test period not exceeding 5 minutes. 17/ The tuner drive mechanism shall not be set against either mechanized stop. 18/ The tube shall be fastened rigidly to the vib

28、ration platform and vibrated with a simple harmonic motion at F = 10 to 55 to 10 Hz in 1 to 3 minutes at 10 G or 0.060-inch double amplitude. This cycle shall be repeated for a total of 90 minutes in each of three mutually perpendicular planes, and then the tube shall be vibrated for 30 minutes at e

29、ach of the resonant frequencies noted. 19/ The frequency drift from start to stabilized frequency shall not be more than the specified amount, and at least one-half of the total frequency drift shall occur during the first 2 minutes of a 5-minute test period.

Testing and inspection - Continued. 20/ After thermal equilibrium has been reached, the frequency obtained by turning the tuner from the beginning of the frequency range to the specified setting in one direction sha

31、ll be reproducible within the specified limits when returning to that same setting from the extreme opposite direction. 21/ Life test shall be run with heater power frequency set at the major resonant frequency, if any, as determined by the heater-structure test, provided that the resonant frequency

32、 occurs between 55 to 65 Hz or in the range between 340 to 1,800 Hz. If there is no such resonant frequency, heater power may be at any convenient frequency up to 1,800 Hz, at the discretion of the manufacturer. 22/ A cycle for intermittent life-test operation shall consist of the following: Ib Ef M
