Viavi 3920B Platform of testing of analog and digital means of a radio communication

VIAVI 3920B is the platform of testing of analog and digital means of a radio communication.

The platform of testing of analog and digital means of a radio communication VIAVI 3920B in the automatic mode provides fast accomplishment of the sequence of the test procedures checking compliance of characteristics of each user device to specifications of the producer. Such testing and calibration provides reliable results, can be carried out by directly users, occupies the minimum quantity of time (no more than several minutes) and does not require the appeal to the specialized service centers, so, can be executed more regularly and with smaller costs.

Adding of function of automatic testing of the products Tait in Viavi 3920B devices

The Russian representative office of the international company Viavi Solutions announced on October 29, 2019 agreement signature with the Tait Communications company specializing in development and release of the integrated radio communication solutions. Within the agreement of Viavi will provide automatic testing of the products Tait in the flagman Viavi 3920B Radio Test Platform devices.

Among devices for which functions of automatic testing – portable radio stations of lines Tait P25 and Tait DMR intended for police officers of fire and other services which activity is connected with the increased risk will be implemented and requires the guaranteed uninterrupted communication – both for the solution of assigned tasks, and for preserving of own life and health of employees.

For October, 2019 the Viavi 3920B platform works with the broad range of frequencies (from 10 MHz to 2.7 GHz), provides a full range of measurements analog and digital radio systems of different producers and includes sets of autotesting and approval. The platform supports, including, such standards and technologies as AM, FM, SSB, NXDN, TETRA and dPMR.

The complete solution for testing, calibrations and supports of permanent operability of communication devices

On August 28, 2019 the Russian representative office of the international company VIAVI Solutions presented the complete solution for testing, calibrations and supports of permanent operability of communication devices for the emergency and rescue services. The presented solution, according to the developer, will ensure the guaranteed functioning even in the most adverse external conditions, including at the fires and other emergencies. The reliable communication in such situations is crucial – and for accomplishment of a task, and for preserving of life and health of employees.

As noted in VIAVI Solutions, a basis of work of any radio station – the built-in frequency generator which even for expensive high-quality devices can "leave", get off over time. For this reason the radio station requires periodic calibration. Especially it is relevant for digital radio stations with a small step of channels. If this or that channel is occupied, then imposings and failures at enciphering/decoding are possible. In the manual mode calibration can occupy more than half an hour, and requires participation of the qualified technician. It is one of the reasons why calibration is not executed with required frequency. Using the solution for automatic calibration and testing proposed by VIAVI, this work takes no more than five minutes, at the same time can be executed by the employee with the minimum skills. Than the procedure – that high probability is simpler that results will not depend on a human factor and that calibration will always take place according to regulations, claim in VIAVI Solutions.

According to the statement of the developer, the solution VIAVI works practically with all widespread communication systems of different producers – both digital, and analog. Are supported, including, such standards and technologies as AM FM, SSB, P25, DMR (MOTOTRBO), NXDN, TETRA and dPMR. At the heart of a complex – the platform of testing of analog and digital means of a radio communication VIAVI 3920B. The platform works with the broad range of frequencies (from 10 MHz to 2.7 GHz), provides a full range of measurements analog and digital radio systems and includes sets of autotesting and approval.

"Smooth operation of radio station – an important condition for harmonious and safe work of a command in emergencies. Fire extinguishing or elimination of emergency are not only process, but also preparation of technical means. The team of firefighters should be sure that means of communication are completely ready for operation and will not refuse at the critical moment, especially when the visual contact with the workmate is impossible. The complex offered by us for testing of analog and digital means of communication completely solves a problem of support of the equipment in permanent readiness", 'Denis Sladkikh, the chief representative of VIAVI Solutions in Russia 'noted

Features of the Viavi 3920B platform

The features of the platform mentioned by the developer (as of August, 2019):

• The radio signal generator with the low level of a phase noise for testing of key parameters of receivers on radio stations.
• Model 3920B has the broad range of fixed functions and also additional opportunities of testing, the developed digital functions and possibilities of approval of Auto-Test II.
• The device provides a full range of measurements of the analog radio systems and also modern opportunities of digital testing.
• 3920B it is convenient in use and also differs in functions which accelerate testing of the systems of a radio communication and do it reproduced.
• Simple perception of color designation of results "passed tests / did not pass" for operational quality check. Convenient setup of measuring instruments allows to configure settings "passed / did not pass" for each type of the tested system of a radio communication.
• Includes sets of autotesting and approval for the most widespread systems of a radio communication in the industries.
