DG-2630
DG-2630 is Digital Audio Signal Generator manufactured by Unknown Manufacturer.
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 ply 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 inter face formatting can be manually changed regardless of the test pattern. However, L/R-MUTE is changeable at PCM MODE only.
