Description

MT352 is

superior third generation Coded

Dual AGC control option

Orthogonal Frequency Division Multiplex (COFDM)

television demodulator that is both Nordig II and DVB

(as defined in ETS 300 744 specification) compliant. It

can be used in either 2 K or 8 K modes with 6, 7 or

8 MHz channels and is capable of addressing all

modes of transmission.
