Downloaded from https://www.everyspec.com MIL-STD-1311D GRID-PULSE OPERATION The electrical potentials specified on the TSS shall be applied to the tube. Sufficient negative grid voltage shall be applied to cut off the anode current. The cathode shall be preheated for a minimum of 30 seconds before grid pulse is applied. The duration of the test, excluding preheating, shall be as specified. The grid pulse (in time duration, excluding time of rise and time of fall) shall be as specified. Instantaneous anode, screen, and negative grid voltages shall not exceed 1.5 times their specified dc values due to transients. There shall be no evidence of arcing during the last half of this test.
