The Downstream Spectrum Analyzer function provides an analysis of
downstream spectrum in the band between 5 and 2700 MHz. It can demodulate
a signal and show its constellation. Reference level and span can be set by user.
The Upstream function provides an analysis of upstream spectrum in the band
between 5 and 200 MHz. It can easily detect impulse noise.
The Scan function shows the level of all active channels in the channel plan
through a bar chart.
The TILT function measures the tilt in dB obtained from the difference in level
between four carriers. It is useful for equalizing the line.
The Voltmeter function automatically identifies the voltage type (DC or AC) at
the input and the frequency in case of alternating voltage.
In addition, it includes other tools such as datalogger, screenshot, channel plan
editor, etc.
In short, implementation of all these functions into an light instrument,
ergonomic design and robust, makes the RANGER into a productive and
mini
efficient fieldwork tool for the installer.
The RANGER can be expanded with an optical input allowing field
mini
technicians not only to perform optical power measurements but also to do all
the RFoG measurements using a built-in optical to RF converter.
