Unveiling the secrets of the FM radio using PROMAX analyzers

Digital radio is available nowadays in many countries, however the analog FM radio is still among us... and for years to come. So, how does FM stereo work? What can we measure on those signals? Let's have a better understanding of all those topics using the advanced FM analyzer from PROMAX TV spectrum analyzers.

PROMAX signal analyzers and the television production trucks

PROMAX panoramic screen signal analyzers for outside broadcast vans (OB Vans) and production trucks make use of the same technology than portable signal analyzers: They are fail-safe, energy-efficient and low heat emission devices. These are three of the key features required for the equipment to be integrated in field production mobile units.

PROMAX solutions for analysis and monitoring of cable television (CATV) networks

Instrumentation for installers according to DUCT law

The DUCT law 20.808 effective in Chile since 2018 opens up the process of contracting a telecommunications services provider (pay-per-view television, phone, Internet, optical fiber...) and enables final consumers to choose the provider of their choice. This makes obsolete the agreements that forced final consumers to contract the telecommunications provider chosen by their building manager.

DVB-S2 Multistream: Converting from ROOT to GOLD PLS codes

The PLS codes used in DVB-S2 (as well as in DVB-T2 and DVB-C2) can be GOLD or ROOT. Sometimes receivers do not accept both code types so it is helpful to be able to convert one to the other. For your convenience, PROMAX has developed a free online ROOT to GOLD (and vice versa) converter.

The transport stream tables: Their meaning, their content and their purpose

The Transport Stream (TS) tables carry standarized data provided by the broadcaster including instructions for the receiver to properly decode the digital services. Digital services included in a multiplex carry a set of metadata used by the receiver to find the service and to self-configure itself to decode it.

The spectrum monitoring: A new technology for communication signals surveillance and tracking

Spectrum monitoring is a technique to monitor the quality of our RF communication signals that captures, stores and processes raw samples of the spectrum in a frequency band looking for patterns that would indicate a problem. This is a complete new way to monitor the RF spectrum and the PROWATCH Neo integral solution from PROMAX allows up to sixteen RF input signals.

Television e-learning during the pandemic

PROMAX TV analyzers can be remotely controlled over the Internet to do e learning online classes, which makes them a unique-in-its-kind teaching tool and an ally of the telecommunications systems teachers. Also, since they accept all broadcasting technologies, they themselves play the role of a complete grade.
