MIL-PRF-1/1705C
TABLE I. Testing and inspection - Continued.
30/ Peak current through the magnetron shall alternately be the limits as specified under test condition. Test shall be run to exclude the
effects of thermal drift and frequency instability not due to pushing.
31/ Except that "month" in 4.3.8 of MIL-PRF-1 be replaced with "2 months".
32/ The intermittent life test shall be conducted while the phase of a 1.5 minimum VSW R located at a distance of 1 ± 0.05 meters from
the magnetron flange is uniformly and continuously cycled through 360 electrical degrees with a time interval of approximately 30
minutes per cycle. Simultaneously the magnetron frequency, starting at F1, increasing to F5, then decreasing to F1 (see figure 2)
shall be changed approximately 100 MHz increments each 8 hours.
