OUTLINE
DG-2630 generates the test signal by the IEC61937 (with MPEG-2 AAC) and IEC60958 (with PCM) digital audio interface format and measures the characteristic of the equipment which processes the digital signal.
The sampling frequency of PCM test pattern is up to 96kHz.

FEATURES
    MPEG-2 AAC and PCM
        Pre-set test patterns of MPEG-2 AAC and PCM are generated by digital.
        Test patterns of MPEG-2 AAC is fixed. PCM can be rewritten by using RS-232C.
   
    BS digital broadcasting standard
        The MPEG-2 AAC signal comply with the BS digital broadcasting standard in Japan.
   
    Manual operation
        Emphasis bit and copy bit of C-bit, validity flag and L/R-MUTE in digital audio interface formatting can be manually changed regardless of the test pattern.
        However, L/R-MUTE is changeable at PCM MODE only.
   
    Two kinds of output
        The signals are output by coaxial terminal and optical terminal.
   
    External control
        The key operation of a front panel can be controlled through remote control terminal of the rear panel.
   
    Seven segment LED display
        The output signal frequency and the level or pattern No. is displayed by seven segments LED.
   
    Easy test pattern change
        The test pattern is output in order pre-set by the UP/DOWN/TOP key.
