Channel Status
Measurement Functions
Digital audio signals (formats AES3 and S/PDIF) have additional
information called channel status, encoded in the signal bit stream.
The Digilyzer directly translates the contents of the status bits and
displays the results on the channel status screen, thus enabling the
user to directly read the meanings.
The proper interpretation of the status bits is carried out automatically
by the Digilyzer. The first bit of the channel status indicates whether
the status bits are configured in professional or consumer format.
The professional format has various additional information encoded
in the channel status, whereby in the consumer format, the copy
protection is the major concern. ADAT signals do not carry any
status information, so the display will indicate CHANNEL STATUS
NOT AVAILABLE ON ADAT.
To display the complete status information three different pages are
available:
• page 1, main status information
• page 2, additional status information
• page 3, status information in hex code
The page number is displayed at the top center of the measurement
screen. Select the page number with the cursor and press enter to
select the next page.
