4-3. MODULE FUNCTIONAL DESCRIPTION (Cont)
CLOCK AND COUNTER MODULE 1A1 Generates range pulses when 5 MHz clock and sweep gate signals are applied
from signal processor. Range pulses represent targets occurring at ranges up to 100 km. During each sweep gate time,
one range pulse is output on the switch gate line to oscillator and switch module 1 A2. The target range represented by the
range pulse is determined by the settings of X SELECT, Y SELECT, TARGET WIDTH, and RANGE switches. MT GEN
switch controls +5 Vdc and +20 Vdc to the clock and counter module. Setting MT GEN switch to OFF position disables
switch gate signal.
