· For details on the connection method etc., refer to the Test Program Specifications KES-92654.
· Since a 2 track in digital coaxial 1,2 receiver has been selected in 1,2, use a coaxial cable ( 50 , 50m ) for the connection for
those terminals.
· Output 03D oscillation 1 kHz to ST OUT and YGDAI SLOT.
(1) Fs = 51.12 kHz (48 kHz + 6.5 %)
· Set the function generator to 51.12 kHz.
· Test listen with headphones for 30 seconds and verify that there is no noise.
· Change the connection between the DIGITAL I/O CONSOLE terminal and the DIGITAL I/O ENGINE terminal.
(2) Fs = 39.69 kHz (44.1 kHz -10 %)
· Set the function generator to 39.69 kHz.
· Test listen with headphones for 30 seconds and verify that there is no noise.
· Change the connection between the DIGITAL I/O CONSOLE terminal and the DIGITAL I/O ENGINE terminal and check
