DANTE LEADER CLOCK WITH GNSS SYNCHRONIZATION
Tone Generator Menu
The Model 5402’s tone generator function is capable of creating eight precision sine wave tones with independent fre-
quency and level configuration. The frequency range is 1 to 22000 hertz (Hz) and the level range is –99 to 0 dBFS.
The tone signals have Dante transmitter (output) default names of
Tone 1
through
Tone 8
. It’s expected that most applica-
tions will only use a few of the tones. But having eight output channels provides flexibility in creating a set of tones with
various frequency and level combinations. These can be useful in a range of applications including identifying individual
channels in a multi-channel arrangement, e.g., stereo, 5.1, or 7.1.
Frequency (Hz):
These eight fields reflect the Model 5402’s
currently selected sine wave tone generator frequencies.
For each channel enter the desired frequency in full hertz.
Don’t use a suffix such as k or kHz, nor enter a comma
or period to delineate thousands. Entering 1001 would be
correct while 1,001 or 1.001 k would not be acceptable.
The default tone frequencies were selected in hundreds of
hertz with the first digit matching the channel number: 100,
200, 300, etc. This can be useful when checking a series
of channels as this pattern can be easily recognized either
by ear or using equipment that can display the frequency
in text. Some applications may need the common 1000
or 10000 Hz reference sine wave tones and there’s no
problem configuring these if desired.
Level (dBFS):
These eight fields display the level of the
Model 5402’s sine wave tone outputs. The output level for
each of the audio output channels is independently adjust-
able over a range of –99 to 0 dBFS. The level is selectable
in 1-dBFS steps.
Enter the desired level in full dBFS with a hyphen as the
prefix to indicate less than full scale. In applications that
comply with the SMPTE® audio standards the typical nomi-
nal level will be –20 dBFS which can be thought of as 20
dB less than full scale or digital 0. In EBU applications the
typical nominal level will be –18 dBFS. Some applications
may benefit from a sine wave test tone that’s 12 dB less
than the reference level. This would equate to configuring
an output to –34 dBFS (SMPTE) or –32 dBFS (EBU). These
would typically be associated with a 1000 Hz tone.
The default tone levels were selected in a pattern that could
help identify a specific channel. Dante transmitter (output)
channel Tone 1 has a default level of –21 dBFS with the
value of 1 being selected to reflect the channel number.
Each subsequent channel then reduces its level by 1 dB.
So, for example, the second channel, Tone 2, has a level
of –22 dBFS. While these level steps may not be readily
discernible to human ears most test equipment or metering
could easily be used to identify specific channels.
Submit:
A Submit button is located at the bottom of the Lev-
el (dBFS) column on the Tone Generator menu webpage.
To save any changes made to the level or frequency fields
requires that the Submit button be pressed. Changes will
be made immediately after pressing the Submit button.
