Le FPV est rendu possible grâce à deux liaisons RF, une liaison de contrôle et une liaison vidéo. Sans un wattmètre RF, un pilote n'a aucun moyen de tester ces liaisons RF critiques. L'équipement de test pour les liaisons micro-ondes (GHz) n'est pas bon marché. ImmersionRC a changé cela il y a plusieurs années et a fourni son « Power Meter V1 » à la communauté FPV. Le V2 est le résultat de l'écoute des commentaires des clients. ImmersionRC a ajouté une batterie interne, un atténuateur interne et d'autres fonctionnalités dont chaque FPVer a besoin.
Mesures précises de la puissance RF
Le dernier VTX à la mode est-il vraiment aussi performant que le prétend sa fiche technique ? Émet-il vraiment 25 mW sur tous les canaux de course ? Émet-il toujours 25 mW 30 minutes plus tard ?
Le RF Power Meter V2 permet de répondre à ces questions et à bien d'autres.
Au tout début des courses FPV, ImmersionRC a été le pionnier des courses à faible puissance, où tout le monde utilise 25 mW. Cela est devenu une norme mondiale en quelques mois et continue d'être la norme aujourd'hui. Le Power Meter V2 vous offre l'outil de mesure dont vous avez besoin pour tester les émetteurs avantvous êtes surpris à la course suivante.
Conformité aux courses sans contact
Êtes-vous prêt à tester votre émetteur vidéo avant que le marteau ne sorte ?
Avec le dipôle court inclus, le RF Power Meter V2 est tout ce dont vous avez besoin pour effectuer un test de puissance approximatif sur n'importe quelle plate-forme FPV, même sans dévisser son antenne. Calibrez le compteur sur une plate-forme « connue pour être en bon état » et parcourez la grille de départ pour tester chaque quad prêt à courir. Les quads réglés accidentellement sur une puissance élevée (prêts au marteau), ou ceux qui ont des problèmes de matériel/câble/connecteur/antenne émettant quelques micro-watts sont identifiés avant la première porte.
Nous appelons cela le « mode Scully » pour une bonne raison. Joe Scully, le meilleur maître de stage FPV du secteur, a perfectionné cette technique de test pour garantir le succès des courses aux quatre coins du monde.
Mode PowerScope
Vous savez donc que des « paquets » de données circulent depuis votre émetteur R/C, ou système longue portée, vers votre modèle… mais que se passerait-il si vous pouviez les « voir » ? Le mode PowerScope du RF Power Meter V2 vous présente une représentation visuelle de la puissance émise par votre radio. À quelle vitesse les paquets sont-ils émis ? La multitude d'antennes de votre radio fonctionne-t-elle ? Où sont-elles ? Quelle est leur orientation ? Vous pouvez même repérer les émetteurs qui respectent les limitations LBT (écouter avant de parler) ou Duty Cycle. Oui, c’est un outil geek, mais il impressionne le sexe opposé !
Mesures moyennes et maximales
Les émetteurs vidéo analogiques émettent un flux constant de signaux RF. Les contrôleurs R/C émettent un flux de signaux pulsés (qui se dirigent simplement dans la direction opposée). Le RF Power Meter V2 peut fournir des mesures de puissance précises pour les deux types de signaux RF.
Batterie Li-ion intégrée
Le V2 contient une batterie lithium-ion intégrée, qui alimentera le compteur pendant au moins 8 heures. Grâce à l'arrêt automatique après des périodes d'inactivité, une seule charge alimentera votre compteur pendant des jours sur la piste de course. Rechargé à l'aide d'un connecteur micro-USB standard en moins d'une heure.

The tool is easy to use and I especially like the antenna as I can easily test the transmission power levels which are bound to my switches. Nice addition to my toolbox.

Great little device... not sure about accuracy but I can clearly tell if my transmitters are within power range.

10/10 Useful tool
Great tool for checking your VTXs! Also helped me confirm the power of my ELRS modules!

Great find!
Just what I needed for my project.

This thing is great. Was really pleased to see that I received a v2 instead of a first gen like was pictured. Was also shocked to see that it actually came because nobody has had these in stock for almost a year. Thanks guys!
