TABLE I. Testing and inspection - Continued.
Class "C" amplifier
Life-test end points
Total grid current
See "Reduced pressure (altitude) rating", and altitude, maximum peak voltage.
Each unit shall be read separately. Control grid of unit not under test shall be connected to -100 V dc.
This test to be performed at the conclusion of the holding period.
Test both units in parallel. Ec1 is a rectangular pulse voltage with a pulse width of 800 µs; this pulse voltage is superimposed
on Ec1 = -100 V dc (total pulse voltage = 160 V.) Duty cycle = 0.04.
Each unit shall be tested separately; ground unit not under test.
Screen grid Mu is determined by measuring grid voltage required to adjust anode current for grid 2 voltages of 210 and 190
volts. Mu = 20/ĆEc1 at Eb = 200 V dc; Ib = 30 mA dc.
Power output is total power at drive frequency delivered to load output circuit adjusted so that Pp does not exceed 2 x 5 watts.
This specification sheet uses accept on zero defect sampling plan in accordance with MIL-PRF-1, table III.
