Mesure de puissance absolue et comparative
Le Keysight E4419B Power Meter est un milliwattmètre RF numérique à deux voies, conçu pour la mesure de puissance de signaux radiofréquences dans les environnements de laboratoire, validation RF, télécommunications et production électronique. Il fonctionne en association avec des capteurs de puissance externes Keysight, permettant d’adapter l’instrument à différentes bandes de fréquence et niveaux de puissance.
Grâce à ses deux entrées indépendantes, l’E4419B permet la mesure simultanée de deux signaux RF, ou la comparaison directe de niveaux de puissance dans un même système. Cette capacité est particulièrement utile pour les applications de calibration, d’alignement RF ou de test de chaînes de transmission.
Associé aux capteurs compatibles, le système couvre une plage de fréquence allant typiquement de 9 kHz à 110 GHz, permettant des mesures sur l’ensemble des domaines RF, micro-ondes et hyperfréquences. La plage dynamique peut atteindre environ 90 dB, avec des niveaux de puissance mesurables allant jusqu’à –70 dBm à +44 dBm selon le capteur utilisé.
L’instrument offre une interface utilisateur claire via un écran LCD graphique rétroéclairé, facilitant la visualisation des mesures et la configuration des capteurs. Il est conçu pour une intégration complète en environnement automatisé grâce à ses interfaces GPIB, RS-232 et RS-422, permettant le pilotage à distance dans des bancs de test.
Le E4419B est particulièrement adapté aux applications nécessitant une mesure fiable de la puissance RF, notamment dans les domaines de la validation d’équipements de communication, de la métrologie RF et du test de composants hyperfréquences.

practical questions about Electrical Test and Measurement
01
Why can an electrical measurement be accurate... but not usable?Because a correct value isolated from its context has little meaning. The actual load, the temperature, the transient regime or the connection mode all have a major influence on interpretation. In electrical testing, relevance depends as much on the measurement conditions as on the intrinsic accuracy of the instrument.
02
What's the difference between measuring to diagnose and measuring to certify?Diagnosis aims to understand a behaviour or locate a fault, and tolerates a certain methodological flexibility. Certification, on the other hand, requires strict procedures, traceable instruments and documented repeatability. The same device can be used for both purposes, but not without adapting the protocol and the level of requirements.
03
Why is safety class as critical as precision?Because reliable measurement should never be at the expense of operator safety. An unsuitable CAT class can expose you to destructive overvoltages, even with a very accurate instrument. In an industrial or energy environment, electrical robustness often takes precedence over the last digit of resolution.
04
When is a specialised instrument preferable to a universal multimeter?As soon as the measurement becomes critical or repetitive. Micro-ohmmeters, megohmmeters or power analysers offer dedicated methods that are more stable and more reproducible than measurements taken with a general-purpose tool. They reduce interpretation errors and provide greater security for technical decisions.
05
Is reconditioned electrical equipment suitable for demanding environments?Yes, as long as it is requalified and documented. Electrical instruments are based on stable, proven architectures. Serious reconditioning, including functional and metrological verification, can deliver performance levels that are suitable for maintenance, production and R&D, with better control of lead times and costs.
