Data sheet

A USB isolator is a device that electrically separates a USB-connected device from its power and data source, such as a computer or RF set.

It eliminates ground loop problems, protects against electrical noise and reduces electromagnetic noise that can affect signal quality.

For consumer use:

The USB isolator improves the stability and quality of sensitive USB connections, for example for audio interfaces (Groundlift), medical equipment or measuring devices.

It helps protect the computer from power surges and ensures smooth operation without interference or unwanted disconnections.

For amateur radio use:

For radio amateurs, the USB isolator is particularly useful for connecting a transceiver to a computer, to reduce interference, noise generated by the PC and to isolate the ground.

The USB protector works like a USB cable and does not require any driver to be installed. All operating systems are compatible (Windows, MAC, Linux).

Isolateur galvanique USB 2.0

Installé entre un PC moderne et un FT710, c'est à fuir. Que du bruit, plus de signal toutes bandes. Le niveau de bruit est devenu impressionnant malgré une ferrite placée à chaque bout du cable USB blindé de 50 cm. Testé avec plusieurs cables USB. Tous les matériels sont à la terre.

Answer:

Bonjour,

Nous avons bien pris connaissance de votre avis concernant l'isolateur USB 2.0 utilisé avec votre Yaesu FT-710 et nous sommes désolés pour ce désagrément.

Ce phénomène s'explique par la conception même de ce type d'isolateur. Ils intègrent un convertisseur DC-DC pour fournir l'alimentation de manière isolée. Sur des récepteurs SDR très sensibles comme le FT-710, le bruit de commutation de ce convertisseur peut parfois générer des interférences RF qui remontent par le câble, augmentant le niveau de bruit au lieu de le réduire.

Le Yaesu FT-710 gérant généralement très bien la connexion USB directe avec un PC, surtout lorsque l'ensemble du matériel est correctement mis à la terre comme dans votre installation, l'usage de cet isolateur n'est pas forcément nécessaire et s'avère ici contre-productif.

Étant donné que ce produit ne convient pas à votre configuration, nous vous invitons à nous le retourner pour un remboursement. Vous pouvez initier cette démarche directement depuis votre compte client : https://www.passion-radio.fr/mon-compte

Nous restons à votre disposition pour toute question ou complément d'information.

Cordialement,
