Description of Option H08 Modification
The A6A2 LO Driver Assembly has been modified by the installation of a semi-rigid cable
connected between pin 2 of Ul A and an added subminiature coaxial connector (part of the
semi-rigid cable) on the shielded cover for the assembly. This SMC connector is labeled "J3
OUTPUT, 60 MHz". From this connector a flexible coaxial cable (W102) routes the 60
MHz signal to the Al 1 60 MHz Low Pass Filter Assembly mounted on the air deflector at
the rear of the instrument.
