Options
The following options are available for purchase for your NX5. Inform Nautel of your intention to use
any of these options prior to purchasing your transmitter to allow factory configuration and testing.
Standby Exciter
The NX5 supports operation with a standby exciter, which can be installed in the transmitter. With a
stancby exciter you can enable and configure the NX5’s automatic changeover function.
RF Output
The NX5 supports the use of a 1-5/8 inch EIA female connector (standard) or optionally, a 7/8 inch EIA
female connector.
IBOC
The NX5 supports the IBOC digital modulation system. The optional Exgine PWB can be mounted in the
transmitter, and in conjunction with an Exporter, provides the IBOC signal to the NX5 exciter.
DRM
The NX5 supports Digital Radio Mondiale (DRM) radio as a modulation option. An external DRM signal
source (purchased separately) must be configured to provide a modulating signal to the NX5 exciter via
I/Q over AES. Nautel will factory configure the proper pre-correction curves.
Open/Closed Air Cooling
There are two cooling configurations available for the transmitter. See Section 1.4, “Cooling
Requirements” on page 1.4.1 for more information.
GPS Sync Card
A GPS sync PWB can be purchased that is capable of driving a 3.3 V or 5 V GPS antenna. If the optional
GPS sync PWB is installed, it provides the necessary 10 MHz, 1 PPS and 1 kHz sync signals used by the
exciter(s). The exciter uses these signals to synchronize the transmitter’s carrier frequency and phase to
this GPS reference.
