ETC DG-2630

DIGITAL AUDIO SIGNAL GENERATOR
Digital Audio Signal Generator
DG-2630
Two kinds of output
The signals are output by coaxial terminal and optical terminal.
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.
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.
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.
Easy test pattern change
The test pattern is output in order pre-set by the UP/DOWN/TOP
key.
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 inter face formatting can be manually changed
regardless of the test pattern.
However, L/R-MUTE is changeable at PCM MODE only.
