In other countries, use a peak-indicating instrument as specified by the
regulatory authority in your country.
If you are required to implement the average modulation limits specified
by ITU-R 412-9, you may seldom see peaks hitting
75 kHz deviation. In
this case, we advise you to set the output level using the 8300’s reference
400Hz tone.

Set the digital output level.
A)
Press the
N
EXT
button.
B)
[Skip this step if you are not using the digital output.]
Turn the knob to set the desired digital output level corresponding to
100% modulation, in units of dB below full-scale.
The most accurate way to set this control is by observing a modulation
analyzer connected to your transmitter.
17.
Set the analog output level.
A)
Press the
N
EXT
button.
B)
[Skip this step if you are not using the analog output.]
Turn the knob to set the desired analog output level corresponding to
100% modulation, in units of dBu (0 dBu = 0.776 Vrms).
The most accurate way to set this control is by observing a modulation
monitor or analyzer connected to your transmitter.
If you have set Analog Output Feeds: Monitor in step 10 on page 2-18,
the peak level will not be well controlled because no peak limiting has
been applied to this signal.
C)
Press the
N
EXT
button.
If you activated the modulation setup tone in step (14.A) on page 2-20,
the tone will turn off automatically.
D)
Press the
N
EXT
button.
You have now completed the guided Quick Setup procedure and are in

screen. However, if your country requires you
to comply with the multiplex power ceiling specified in ITU-R 412-9, you
will also need to set up the 8300’s Multiplex Power Controller by follow-
ing the instructions in step 20 on page 2-22.
