17、nt demagnetization. Ferromagnetic materials or energized magnets shall not be brought within 2 inches of the tube. 2/ A calibrated tuner with appropriate dial markings shall be incorporated on the tube. The tuner mechanism shall be capable of setting the tubes frequency within 5 MHz when the tube is

18、 operating at test condition 1 conditions, TA = 25C, and when the effects of frequency pushing and pulling are neglected. The tuner is to be rotated in a clockwise direction for each new setting. A tuner calibration chart shall be provided for each of the 10 frequencies specified below: Channel No.

19、Frequency 1 . F1 2 . F2 3 . F3 4 . F4 5 . F5 6 . F6 7 . F7 8 . F8 9 . F9 10 . F10 3/ High burst duty. The test shall be performed with a pulse train of 1,667 pulse pairs with a pulse pair spacing of 8 s, and an interpair interval of 60 s. This provides a pulse train of 99.96 ms duration. Pulse train

20、s shall be generated every 200 ms. 4/ Low burst duty. The test shall be performed with a pulse train of 333 pulse pairs with a pulse pair spacing of 8 s, and an interpair interval of 60 s. This provides a pulse train of 19.92 ms duration. Pulse trains shall be generated every 200 ms. 5/ High average

21、 duty. The test shall be performed with constant repetition rate single pulses spaced 60 s. 6/ Low average duty. The test shall be performed with constant repetition rate single pulses spaced 300 s. 7/ After the performance of the specified test, the tube shall meet the requirements of conformance i

22、nspection, part 3, life-test end points. 8/ The input capacitance shall be measured between the cathode terminal and a mounting plate .25 inch (6.35 mm) thick with the minimum cut-out required to flush mount the tube. 9/ Spurious emissions shall not have peak power exceeding the specified amount on

23、the tube specification sheet (TSS) within the frequency range of 7.5 GHz and 20 GHz. This limit not applicable within either the designed emission bandwidth or 5 percent of the center frequency in this TSS. 10/ Tubes shall meet the tuner torque requirements after the specified number of cycles. 11/

24、The difference in amplitude between the first and last rf pulse in the pulse train shall not exceed 0.5 dB under the condition that peak current variation of these two pulses be less than 5 percent total. 12/ The difference in frequency between the third and last pulse in the pulse train shall not e

25、xceed the specified value under the condition that peak current variation of these two pulses be less than 5 percent total. 13/ When the filament voltage is varied as specified, the measured frequency shall not change more than the specified amount.

Testing and inspection - Continued. 14/ A life-test cycle shall consist of the following: The frequency shall be shifted starting at F1 to the next higher channel each eight operating hours. 15/ The tube shall be operated int

27、o a transmission line with a VSWR of 1.3:1 minimum, adjusted in phase to produce the maximum spectrum degradation. A suitable spectrum is considered one in which the major lobe has a shape such that its slope does not change sign more than once for power levels greater than the specified dB below it

28、s peak. 16/ Stability shall be measured in terms of the average number of output pulses missing, expressed as a percent of the number of input pulses applied during the period of observation. The missing pulses (MP), due to any causes, are considered to be “missing” if the rf energy is less than 70

29、percent of the normal energy level. A VSWR = 1.3:1 (minimum) shall be adjusted to that phase producing maximum instability and the missing pulses counted during any consecutive 5-minute interval of a 10-minute test interval. 17/ Tuner stops shall be provided to limit rotation of the tuner mechanism.

30、 The lower frequency limit shall not be less than 15.375 GHz and the upper frequency limit shall not exceed 15.725 GHz, with the tuner mechanism “set” against the upper or lower stop. 18/ This test shall be performed using the requirements of either of the specified test conditions.
