With power outputs of 3 kW to 2000 kW, the NX Series sets a new standard for digital performance, rugged design and operational ease in the industry’s most compact enclosure. Add AM digital
precorrection, 90%* efficiency plus an intuitive touch screen interface and the result is the most advanced medium wave transmitter available today.
ADVANCED CONTROL AND REMOTE ACCESS
All NX Series transmitters include Nautel’s Advanced User Interface (AUI). Whether you are on-site in front of your transmitter or at home on the web, 100% of the AUI is available to help you manage your transmitter. Hundreds of parameters are available in real time at your fingertips. Imagine knowing in advance what parts and tools you’ll need at the transmitter site. Having that much control remotely can help you avoid trips, save time and save money.
The touch screen interface is implemented as a non-critical functional unit and may be completely removed from the system without affecting transmitter operation. A backup control interface provides control in case of front panel computer system failure. In addition to web based access the NX Series also supports traditional direct wired contact closure capability for local or remote control.
AWARD WINNING ADVANCED USER INTERFACE (AUI)
The NX Series features an Advanced User Interface with a wide range of configurable displays. The GUI can be controlled by touch screen, or via a mouse and keyboard. Some of the key features of the GUI include:
• Real time network analyzer for antenna cusp analysis.
• Real time spectrum analyzer for spectral mask compliance.
• Complete monitor and control of all functions to the
• Logging of all functions
• 17 inch color LCD screen on NX Series Transmitters 15 kW and above
Screens are easy to set up and read, and clearly display the parameters you need to see.
REAL TIME BUILT-IN INSTRUMENTATION
NX Series transmitters are provided complete with built-in instrumentation that would cost tens of thousands of dollars if purchased separately.
Nautel’s patented, real-time impedance measurement technology allows the antenna system load impedance to be optimized and monitored while the transmitter is operating normally. The transmitted voltage and current waveforms are compared to measure the load impedance over the operational frequency range.
Because this system can measure impedance without requiring artificial swept tones, the antenna system impedance locus can be measured without taking the station off-air. Impedance is measured at the combiner so no correction for harmonic filter phase is required.
NX transmitters also utilize a built-in directional coupler for spectrum measurement instead of a traditional voltage or current sensor. The directional coupler increases the accuracy of spectrum measurement into a real antenna load which is quite important when measuring adjacent channel emissions.
100% REMOTE ACCESS
No matter where you are, you’re only moments away from ensuring your NX Series transmitter is operating optimally. Open a web browser, enter your transmitter’s IP address, and you’re connected. 100% of the local NX Series display functionality is available on any web-interfaced PC or handheld device via the internal NX Series web server. Users can access status, controls, alarms, logs and reports via the internet.
NX Series transmitters also support Simple Network Management Protocol (SNMP), a network protocol that allows network management systems or a network operations center (NOC) to monitor network attached NX Series transmitters.
