Signal analyzers to install Maritime Internet. How does the Internet work in the sea?

Most boats mount motorized satellite antennas that are constantly aligned with the telecommunications satellites. Through these satellite dishes, all kinds of telecommunications are sent and received: Internet, telephony, television and data. RANGER Neo TV and Spectrum analyzers are perfect for field work because they are shock protected and they feature more than four hours of battery operation time.

How to locate pirate radio and TV stations with PROMAX solutions

PROMAX designs several monitoring and spectrum surveillance systems. The government authorities in charge of the surveillance of the radio-electric spectrum can use the PROWATCH instruments to detect and locate the pirate and irregular broadcast stations of radio and TV.

How to perform a perfect fusion splicing of two optical fibres

In this video tutorial we are demonstrating how to fusion splice two optical fibers with the ultra thin fusion splicer model PROLITE-42. After this, you will learn how to check the connection for losses. We will use a PROLITE-105 calibrated light source and a PROLITE-67 selective power meter.

Unveiling the DOCSIS 3.1 technology

DOCSIS 3.1 brings a good number of new technologies to the table which put together become the essence of this new powerful CATV standard. Here you will find these innovative developments as well as their related jargon explained below. DOCSIS 3.1 extends the Upstream band up to 192 Mhz and the Downstream band up to 1.2 Ghz (optionally up to 1.8 Ghz) with the objective of increasing network capacity.

The power measurement of a digital channel differs from its vertical scale in the spectrum analyzer. Why?

The power of a digital channel is calculated using algorithms that evaluate the received energy through its entire bandwidth. The result of these calculations will differ from the vertical scale of the graph depending on the bandwidth of the signal that is being measured. These values will be more different as the bandwidth increases. How is this measurement calculated? How are we doing at PROMAX to guarantee and improve its accuracy?

How to check coaxial wiring at facilities

Coaxial wiring in new buildings (with no headend equipment installed has to be checked using a pilot carrier generator connected to the headend and a field strength meter certifying the reception levels in each outlet. For those facilities with installations in operation, each section can be checked in the same way, disconnecting and testing one section at a time.

FM radio is coming to an end? PROMAX develops new technologies for DAB and DAB+ analysis

PROMAX has a new type of demodulator for DAB and DAB+ that can be optionally installed into the RANGER Neo field strength meters so that they be equipped with the most versatile DAB/DAB+ analyzer available today. It includes an expanded frequency margin of up to 800 MHz, among other benefits over the rest of DAB analyzers of the market.

What do PON, GPON, XG-PON, 10G-EPON stand for? Which analyzers are compatible with them?

PON stands for "passive optical network" referring to the optical network composed by non-active components in all stages between the origin (local exchange) and the external sides (subscriber or clients). The others acronym (GPON, XG-PON…) corresponds to the standard transmission that travel through this physical network. In which are they different?

What do RMS and True RMS stand for? Here we explain you the differences

The TRMS instruments are much more accurate than the RMS when measuring AC current. This is why all the multimeters in PROMAX catalog have True RMS measurement capabilities.

PASS / FAIL: It may turn against you

The PASS/FAIL function is widely used in measuring instruments. Specifically talking about field strength meters it may become a great ally to check signals quickly, which turns into a double-edged sword in the hands of users if they do not know what they are doing. It is necessary to take into account certain variables that cannot be diagnosed by a simple PASS / FAIL function.
