Figure 1.
The RANGER mini includes all the necessary functions to carry out the
installation of any service in terrestrial, satellite or cable systems, including fiber
optics if this option is installed. Each system has a series of helpful tools for each
task.
The Spectrum Analyzer function provides an analysis of spectrum in the band
corresponding to the system selected. It can demodulate each 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 205 MHz, which allows you to easily detect problems in that
band, such as impulse noise.
The Scan for terrestrial and cable 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 and to connect to a external device (PC, tablet) via Ethernet.
The RANGER mini can be expanded with an optical input allowing field
technicians not only to perform optical power measurements but also to do all
the RFoG measurements using a built-in optical to RF converter.
