Note:
When adjusting the sensitivity level of the inputs, keep in mind that the menu
shows the instantaneous modulation level. For correct adjustment, it is therefore
advisable to apply to the input a dBm signal with a level equal to the entered
dBu level.
To adjust the levels of the inputs of the sub-carriers, a similar procedure can be
used, using the option
x10
that can be selected in the
MIX
menu. With this option,
the indicated modulation level is multiplied by a factor of 10. The indication of
75 kHz actually coincides with a deviation value of 7.5 kHz.
