ACCURACY

The Navigator-Modulation analyzer uses 100% digital technology. All measurements are performed algorithms of demodulation decoding, filtering, and weighting. Computations are independent of the material.
Except for the D/A and A/D converters which are some of the best on the market, the precision of the measurements is dependant only on the precision of the calculations.
For instance, it is possible to compute the excursion of a modulated signal with a precision better than 0.5% (typically 0.2%).
This product can be used as a reference for the quality control of a program using the digital AES-EBU output just because between the RF input and the digital output, the signal is always digital.

APPLICATION SOFTWARE ERGONOMICS

Some measurements are done on the front panel with a touch screen (for field measurements), or via a PC software (for lab measurements), which can be adapted to a variety of uses.
Clear, accurate and integrated view of the required parameters for controlling and adjusting the FM transmission chain.

INPUTS / OUTPUTS

Through a variety of interfaces, Modulation Analyzer can be used at any point of the transmission chain.

Inputs:

Stereo analogic and stereo digital (AES-EBU) to analyze studio output, listen to AES-EBU input (with headphone).
Composite input to check levels at audio processor output, stereo encoder, RDS encoders, and also to check RDS data.
RF input to check RF power and spectrum, and also every level of the composite signal.

Outputs:

Digital (AES-EBU) and analogic L/R output to check the modulated audio signal.
2 configurable analogic composite outputs to make specific control, compare performances, linearity.
A programmable headphone output to listen to audio during measurements.

FUNCTIONS

On production line:
You can qualify your transmitter entirely. Navigator Modulation Analyzer is a complete tool to calibrate, adjust RF or stereo ports or make a complete check up.

On transmition site:
As measurements are available in real time, you can visualize RF spectral representation but also MPX and Left & Right spectrums. The user can control excursion and every level injections through bargraphs.
As the equipment is multi-client, your technician can use the equipment while your expert checks remotely (depending on your network) every available measurement with the same configuration.
You will be able to maintain and troubleshoot your equipment faster.

OTHER FUNCTIONS

Communication IP:
The standard application software can be used from a distant PC and send command to the equipment via network. A production or maintenance center can centralize the management of all its Navigator Modulation Analyzers from one or several management center.

Automatic reports:
The application software can generate automatic measurement reports. The user can modify the presentation of these reports, the software offers a standard model with most of the results and also some graphical representation essential for a complete FM broadcast measurement session.
All panels are caught and saved on your local hard drive and a txt file including all numeric values is created.
The report shows additional information like serial number, revision number, data of calibration.
