MIL-PRF-1/1383D
TABLE I. Testing and inspection - Continued.
20/
This test is to be the first test performed at the conclusion of the holding period.
21/
The tube shall be tested in accordance with MIL-STD-167-1.
22/
Test is to be performed in accordance with MIL-STD-202, method 207. The height of hammer drop shall be 1 foot. A total of
nine blows shall be applied, three blows being applied to each of the three principal axes.
23/
The magnitude of any spike on the anode voltage pulse shall not exceed its peak value by more than 4,000 volts and the
duration of any spike when measured at the peak-value level shall not exceed 10 percent of the maximum "on" time. In the
absence of rf output voltage, the peak-pulse supply voltage may exceed 33,000 volts for no more than 10-consecutive pulses,
but under no circumstances shall the instantaneous value of the pulse-supply voltage exceed 36,000 volts. The output cavity
shall be pressurized as required to prevent corona or external flash-over at the ceramic bushing.
The magnitude of any spike on the grid 2 voltage pulse shall not exceed its peak value by more than 250 volts and the
duration of any spike when measured at the peak-value level shall not exceed 10 percent of the maximum "on" time.
24/
Test shall be performed with no voltages applied except as necessary to indicate shorts.
