Como es habitual, recibido en tiempo garantizado. En cuanto al comentario respecto a los atenuadores, adjunto imágenes con los resultados medidos en el caso del de mayor atenuación (-20dB) que es el que mayor desviación del valor nominal pudiera presentar. Las imágenes corresponden a las calibraciones: 1 a 60 MHz 130 a 170 MHz 400 a 480 MHz 10 KHz a 4,4 GHz Las tres primeras medidas arrojan resultados con valores más o menos lineales. Donde más se aprecia una ligera “no linealidad” es en la calibración de 10 KHz a 4,4 GHz donde se puede apreciar que a partir de poco más de unos 2 GHz hay una ligera oscilación en el valor medido. Por supuesto que no son elementos de laboratorio, pero por el precio que tienen son aceptables para trabajos no profesionales.

Die Teile weisen sehr gute Werte auf. Messergebnisse passen exakt zu meinem VNA. (kein R&S) Sehr gut verarbeitet.

Ho acquistato 2 set di attenuatori al prezzo di 45.95 euro ciascuno, consegna puntuale e valore nominale degli attenuatori come da descrizione. Li ho caratterizzati a 144, 432 e 1296 MHz con VNA calibrato e questi sono i dati che ho ricavato: Precisione sul valore di attenuazione S21: entro +- 0.1 dB per tutti i pezzi tranne i 2 attenuatori a -6 dB (-5.83...-5.89 dB misurati) e 1 attenuatore a -20 dB (-19.84...-19.93 misurati). Return loss S11 e S22: per 144 e 432 MHz sempre migliore di -40 dB (SWR 1.02). A 1.2 GHz sempre migliore di -35 dB (SWR 1.04). Per i miei scopi sono ottimi!

Adequate for most non-Hams working on the 2.4Ghz ISM bands which are limited to 30 dBi (1 watt) here in the U.S. It's a handy set to complement my electronic attenuator, and a necessity if you are working with an SA or VNA. These are 50 ohm SMA devices, so it you are working satellite stuff, you may need 75 ohm "F-type" anttenuators. Fairly priced and looks to be nice build quality, I'll give them 5 stars, and update if I find any significant discrepancies. Cheers!
