10、 fi dc _- This test is to be the first test performed at the conclusion of the holding period. Class AB linear RF amplifier single sideband suppressed carrier operation, both sections in parallel. Maximum glass and seal temperature shall be 250C. When operating the tube at maximum ratings, with forc
11、ed air cooling, it is necessary to cool both the lateral bulb surface as well as the anode pin seals by directing the flow of air toward the top and sides of the bulb. In most cases, approximately 20 cfm is sufficient. At reduced ratings, the use of heat sink is permissible. However, regardless of t
12、he type of cooling being used, the degree of cooling shall be determined by direct temperature measurement of both the seals and the bulb. Power output is total power at drive frequency delivered to load. Drive power is not subtracted from total output. Output circuit tuned for maximum power output.
13、 Read each unit separately. Grid (1) of section not under test shall be connected to -1 O0 V dc. Tie both anodes and the screen together. The pulse duration measured at 5 percent of the maximum value shall not be less than 3 p. At 50 percent amplitude, the duration shall be less than 2 YS. The appli
14、ed voltage shall have a maximum repetition rate such that the duty cycle, based on the pulse length measured at 50 percent amplitude, shall not exceed 0.0002 (0.02 percent). The test shall be duplicated on each unit separately. The unit not under test shall be tied to ground. Shielding shall be in a
15、ccordance with figure 2. Operation as class “AB1“ amplifier, Q = 10 minimum. Power output is total power at drive frequency delivered to load. Drive power is not subtracted from total output. Output circuit tuned for maximum power output. Drive to true “O“ bias point condition which shall be met aft
16、er all tuning is completed. Ef = 13.25, Eb = 800 V dc, Ec2 = 325 V dc, anodes and grids (1) in parallel, vary Ecl for Ib = 45 mA dc (total, both sections). These test conditions exceed the absolute maximum ratings and operation shall be limited to 5 minutes maximum “ony time followed by an “off“ tim
17、e of at least 5 minutes. Total “on“ time for power output (1) plus power output (2) tests shall be limited to 5 minutes with power output (3) test requiring as short a time as possible beyond the 5 minutes to reach stabilization. Vibration test shall be checked annually, using a sample of three tube
18、s with no failures allowed. In case of a sample failure, the test shall become a part of conformance inspection, part 2, for three consecutive successful submissions, at which time the test may revert to the conformance inspection, part 3 test. 3 Provided by IHSNot for ResaleNo reproduction or netwo

The tube base shall be capable of entering to a distance of 0.375 (9.53 mm) a flat plate gage having six holes 0.0800 (2.03 mm) kO.0005 (0.01 mm) and one hole 0.1450 (3.68 mm) 10.0005 (O.Olmm), all arranged
22、on a 1 .O000 (25.40mm) f0.0005 (0.1 mm) circle at the angles f5 specified on the outline. A 0.500 (12.70mm) fO.O1O (0.25mm) diameter hole at the center of the pin circle shall also be required. The axis Y - Y is defined by the center of this hole. The anode leads shall be capable of entering a flat
23、plate gage of 0.375 (9.53 mm) kO.001 (0.03 mm) thickness having two holes 0.2000 (5.08 mm) i0.0005 (0.01 mm) diameter spaced 0.365 (9.27 mm) 3.001 (0.03 mm) from a point coincident with the axis Y - Y. The axes of the holes shall be parallel to axis Y - Y and the plane of these axes shall be 90 degr
