Basis of Selection
Selects scaling of current drive of YIG Oscillator
FM coil near 100 kHz.
Selected at factory to correct for frequency
nonlinearity in YIG Oscillator A12.
Allows maximum marker OFF pulse without
overlapping the ON pulse.
Center the range of 50
mHz frequency adjustment.
Minimizes feedthrough of 27.8 kHz square wave
into the external marker birdie.
Factory selected to optimize A12 YO band-
width, power, and harmonics
(not field replaceable).
