Carrier Level displays the measured peak-to-peak amplitude of the digital audio carrier. The displayed
value is only meaningful when the input connector is set to BNC or XLR— for optical or GenMon inputs
the display shows the amplitude of an internal signal.
Measured Fs displays the measured frame rate of the digital audio signal. For single connector digital
audio inputs this will be equal to the effective sampling rate of the digital audio data. For dual-connector
digital inputs this value will be half the effective sampling rate. When "Square Wave" is checked on the
input configuration panel, the frequency reported is simply the measured frequency of the input square
wave.
Delay measures the delay specified by the Delay Mode control. When Delay Mode is set to DigOut-
>DigIn the Delay field displays the delay from the z-preamble (beginning of digital audio block) of the
digital audio output signal to the z-preamble of the digital audio input signal. When When Delay Mode is
set to RefOut->DigIn the Delay field displays the delay from the z-preamble of the rear-panel
digital audio
reference output to the z-preamble of the digital audio input signal.Both these values can be used to
measure the transmission delay through a device depending on whether the rear-panel reference or the
main digital audio output is used as a source.
