An approved noise source shall be used for noise figure measurements. Power input level shall be about -75 dBm
12、 for power gain (1), noise figure (1), power gain (2), and noise figure (2). 3. Envelope strain procedure. Tubes shall be tested as specified in MIL-STD-1311 method 2126, except that they shall first be immersed in water at not more than 5C for 15 seconds, and immediately thereafter subjected to the
13、 standard temperature cycle specified in method 2126. The criteria for air leaks shall be heater current of 330 mA, or more. 4. Vibrate in plane perpendicular to the plane of the grid. Test 10 tubes selected at random from the first production lot of each calendar year, and approximately every 90 da
14、ys of production during the year. If one tube fails to pass the specified end points, the test shall become a part of conformance inspection, part 2, acceptance level of 6.5 (see note 6). After three consecutive successful submissions, the test shall revert back to the 10-tube quarterly test. 5. App
15、ly the force perpendicular to the plane of the grid from the cathode end. Test 10 tubes selected at random from the first production lot of each calendar year. If one tube fails to pass the specified endpoints, the test shall become a part of conformance inspection, part 2, acceptance level of 6.5 (
16、see note 6), on all lots in process. After three consecutive successful submissions, the test shall revert back to a 10-tube annual test. 6. This specification utilizes an accept on zero defect sampling plan in accordance with MIL-PRF-1, table III. 7. Drawings 270-JAN, 271-JAN, 272-JAN, 273-JAN and

These dimensions shall be checked on a lot-to-lot basis under conformance inspection, part 2 to an acceptance level of 6.5, inspection level S3. The acceptance level is a
21、pplied to each dimension separately and is not combined. 2. These dimensions shall be inspected at the start of production and periodically every 3 months during production. The sample size shall be six tubes and the acceptance number shall be zero defects for each dimension. Failure of any dimensio
22、n to meet conformance inspection, part 3 requirements shall cause the nonconforming dimension to be inspection on a lot-to-lot basis to a 6.5 acceptance level, inspection level S3. After three consecutive successful submissions, the inspection shall revert to 3-month intervals. 3. All tubes are to b
23、e 100 percent tested for concentricity in gauge (see figure 3). Tube shall be rotated 360 in gauge without binding. 4. Grid shell seal shall be completely filled to cathode ceramic shelf. 5. T dimension shall be measured other than across tube designation etch, and approximately .100 (2.54 mm) from
24、the reference plane. 6. V dimension shall be measured approximately .100 (2.54 mm) from the end of the anode terminal. FIGURE 1. Outline drawing of electron tube type 6299 Continued. FIGURE 2.
