Audio Mode

For instruments with only video modules installed, Audio mode provides a protocol-level check for the AES stream. The Embedded Audio Status screen reports the following information:

HWhich video input is the source of the embedded audio

HThe standard used by the audio signal

HWhether the header indicates that audio is present on each pair of channels (Status = Present or Not Present)

Audio Mode (Option DG Only)

NOTE. The information below describes the Audio mode display for instruments with the Option DG audio module installed.

Configuring the Instrument for Audio Measurements

Selecting Which Audio Input to Monitor

Use the following submenus of the Configure menu to set the various instrument parameters for audio measurements: Audio Inputs/Outputs, Audio Displays, and Audio Thresholds. Use the Configure Alarms submenu to configure the audio alarms.

Use the Input menu to select which audio input the instrument will monitor. Select Embedded to monitor the audio signal embedded in the selected video signal input, or select Ext AES to monitor the audio signal(s) connected to the Option DG audio module.

NOTE. When you set the function of the AES connectors to output, embedded audio is automatically selected as the audio input source. You cannot monitor audio signals on the AES connectors until their function is set to input (use the Audio Inputs/Outputs submenu of the Configure menu).

When you select Embedded or Ext AES as the audio input source, the instrument maps the audio signal to the level-meter bars as configured by the Embedded Input Map or the AES Input Map in the Audio Inputs/Outputs submenu of the Configure menu.
