DIGITAL OUTPUT AND CARRIER ARCHITECTURE
Digital Output parametersOutput wordlength is adjustable between eight and 24 bits, with optional addition of DC offset and dither.
Transmitted flags including Valid bits, User bits and all Channel Status fields can be set as required. These can be set from a simplified dialogue:
Or from an "advanced" dialogue which gives access to all parameters.
At high sample-rates, the Digital Output can be configured to operate in 'Split96' (or 'two-wire') mode, where a single channel is transmitted over a single AES3 carrier at a frame rate of half the sample rate.
Digital Output Carrier parametersOutput Carrier phase with respect to the Reference Sync can be adjusted.
Output Carrier jitter can be added, with sine, wide-band noise or audio-band noise functions. The low-frequency sine function with up to 20UI amplitude is available for testing jitter tolerance to the AES3 template.
Carrier amplitudes and rise/fall times can be set independently for the XLR and coaxial outputs.
Differential wide-band noise interference can also be added to these outputs. Common-mode interference can also be added to the XLR output.
Many of the degradation functions can be output from the Monitor Outputs if required.
These settings are controlled through the Digital Output Carrier dialogue box:
