The rate of change of ambient temperature shall not exceed 2C per minute. z/ The tube under test shall be nonoperating and
12、 rigidly mounted on the vibration table. The frequency range, 20 to 55Hz, shall be traversed in approximately 1 minute. The motion shall be appGed for a period of 30 minutes in each of the three mutually perpendicular planes, one of which shall be parallel to the axis of the beam. 81 The tube under
13、test shall not be oscillating during this test. 9/ Forced air cooling shall not be used. - 101 Apply heater voltage for 2 minuteS.Then apply other voltages plus heater voltage for 2 minutes and read the total reflector current at the end of the latter 2minute period. 111 The frequency shall be allow
