Electrical measurements are to be made with a standard frequency source having an absolute accuracy of the order of 1 part in 500,000. The cavities shall be tested mounted between UG-40/U chokes in RG-
13、52/U waveguide and with a voltage standing wave ratio less than 1.05 due to resistive match looking into each of the chokes between which the cavity is mounted. 2. The difference in resonant frequency before and after vibration shall not exceed the limits specified. 3. The cavity shall be subjected
14、to three complete cycles between the specified temperature extremes. The cavity may be allowed to come to equilibrium at room temperature in passing from one extreme to the other. The cavity shall be maintained at the extreme temperatures for the specified time during each cycle. When the tube has c
15、ome to equilibrium at room temperature at the conclusion of the last two half cycles, the resonant frequency shall be measured and shall be within the specified limits. 4. After temperature cycling described in note 3, the cavity shall be brought to equilibrium at the specified extreme temperature f
16、or 30 minutes and then returned to equilibrium at room temperature. Then it shall be brought to the specified extreme temperature again and allowed to return to room temperature. Resonant frequency measurements shall be made at approximately 20C temperature intervals while returning to room temperat
17、ure. At no temperature shall the resonant frequency differ from the value at room temperature by more than the specified amount.

18、ical diffuse low-pressure glow discharge when placed in an rf field. 6. The cavity may be allowed to come to equilibrium at room temperature in passing from one extreme to the other. The cavity shall be maintained at the extreme temperature for the specified time during each cycle. When the tube has
19、 come to equilibrium at room temperature, at the conclusion of the last two half cycles, the resonant frequency shall be measured and shall be within the specified limits. 7. Fo at -55C may be obtained by extrapolation of the data obtained at higher temperatures. 8. This test is not applicable to ty
