when music continuously alternates between loud and soft, and enables an announcer to
speak over it.
Note In MPX mode (input 2 or input 3) the MPX power limiter is always deactivated. In this case
the external source must ensure compliance with the ITU recommendation.
2.7.5 Exciter > RF Menu Window
In the RF menu you set the output frequency and also enter settings for the clock reference.
Setting item Description
Frequency Setting for the output frequency
Value range: 87 500 000 Hz through 108 000 000 Hz
Step size: 10 000 Hz
Clock Reference Sets the reference for the internal oscillator
Possible selections
a)
– Internal (the built-in TCXO is used; default setting)
– External PPS (one pulse per second from an external source;
optional)
b)
– External 10 MHz (a 10 MHz clock from an external source; optional)
c)
– External AES (the AES/EBU signal clock)
a) Alternately overwrites the corresponding setting in the Exciter > Static Delay menu window.
b) Can only be used when the SR8000-B2 "External Reference" option is installed.
c) Can only be used when the SR8000-B2 "External Reference" option is installed.
TCXO Trim Value For adjusting the internal TCXO
d)
Value range: -100 % through +100 %
Step size: 0.01%
d) The value is sent straight to the hardware, i.e. there is no need to confirm the entry with OK. The effect of the
setting can be monitored straight away by simultaneously measuring the output frequency. The value is per-
manently saved when the setting has stayed unchanged for around 30 seconds.
