Under the conditions specified, the tuning mechanism shall be smoothly operable throughout the entire mechanical tuning
range without the specified torque being exceeded.
30/
The tuning mechanism shall withstand the maximum specified stop torque at the extreme ends of the tuning range without
damage.
31/
Tune tube to 15.8 GHz and measure the reflector voltage at mode center. Turn tuner one turn counter-clockwise and
measure reflector voltage at mode center for this tuner position. The difference in reflector voltage divided by the one turn
change in tuner position shall not exceed the limit specified.
32/
After completion of this test, tube shall meet the requirements of power output (1) and tuner torque.
33/
