livré en 3 jours ; merci Amazon !un superbe produit pour 400 euros.J'ai longuement hésité entre celui-ci et le modèle 4 voies. Mais pour le même prix j'ai préféré prendre le 200MHz à deux voies seulement. Pour faire de la "petite" électronique Arduino, audio, mesure basse fréquence ça devrait me suffire pour un moment.Facile d'utilisation, bien pensé. Boutons agréables au toucher, réponse rapide.Il y a un petit ventilateur mais il ne fait presque pas de bruit, et je suis très sensible à ce genre de détail.Pas encore eu le temps de tester la fonction de décodage des trames.

Llegó en buen estado se realizaron pruebas básicas de funcionamiento ya que aún no estoy familirializado con sus menús. De momento no hay algún problema con el equipo.

Tiene caracteristicas que la mayoria no tiene, como un delay de triger para ver la posición que te interesa, un zoom muy fácil de manejar con un preview que permite navegar en el zoom muy facilmente. El decodificador serial me sirvio para revisar el protocolo de una tarjeta viejita que no me acordaba a que frecuencia trabajaba. Al menos a mi me salio muy muy barato con MSI tuve suerte, ya no lo he encontrado a ese precio. Exceletne proveedor llego en tiempo y forma.

The other reviews mention many great features ranging from the 1GSPS, 200MHz bandwidth, FFT, and range V/div starting at 0.5mV. So i won't repeat these for the Siglent SDS1202X-E that I purchase on July 31, 2021. This is an excellent scope for the price. Don't let people mislead you into thinking that it's only for beginners (it's not) but certainly beginners will be able to use it. Compared with my HP54111d from the 1990s costing $20k when new and having 500MHz Bandwidth and 2Gsps, the little Siglent does far more and better for far less price (but only 1Gsps and 200MHz bandwidth).Others mention concern over the serial numbers and the 'droop' related to probe calibration. My serial number is not the BA. However, I will mention that the 'quick start guide' accompanying the unit had an addendum page regarding calibration that indicated the unit was calibrated several years ago which appears to indicate the unit left the factor at that time. So the BA serial numbers must have been fixed by then.Other people have mentioned concern over high levels of noise on the 0.5 mV through 5 mV ... actually not a problem. But here's my story. When I first started the unit on Monday around 4pm, I shorted the probe tip to its ground and noted wildly varying 'noise' on the 0.5mV - 2mV scale and that would make the scale useless. I removed the probe and instead attached a banana-to-coax adapter and shorted the two inputs with a wire. Whoa still wildly varying noise. Bringing my hand closer to it increased the noise by a factor of two. I began to think there was a problem with scopes ground circuitry to the BNC and some how the noise was coupling through the ground in some type of common mode problem. The FFT showed a spike at the frequency of the FM station down the road at 98.3 ... very cool. Decided to wait till the next day (Tuesday morning) for further tests. The environmental noise levels had dropped by Tuesday morning ... an interesting fact in its own right but still enough for testing. This time, a 50 Ohm cap was placed on the SDS1202X-E input BNC and also placed a 50 Ohm cap on the BNC of my old HP54111D (2GSPS, 500MHz bandwidth). Comparing the two showed similar noise in both on the 1mV scales - here the noise refers to the 'thickness' of the baselines and both were well below 0.5 mV. As a matter of fact the HP unit has dying internal boards that produce a baseline that wavers over about 0.5 mV. With the caps on the Siglent unit, moving the hand closer the 50 Ohm Cap does not result in the wildly varying noise levels. However touching the ground on the cap does result in the scope picking up a small periodic spike maybe 0.25 mV. I'll need to investigate the probes more closely since grounding the tip does not appear to eliminate the nose very well. Anyway, the scope does not appear to have an internal noise problem contrary to some reports.Finally, I wish the power cord could be attached at the back rather than the side of the unit since that uses valuable shelf space or maybe provide a right angle connector for the power cord.Oh and be sure to download the full manual from either the sellers website or the manufacturers website since the unit only comes with the quick start guide.

Perdón, Pero no puedo opinar de algo que no se usar, hoy 9 de octubre 2023 aprendí a usarlo, excelente herramienta, Le compre su estuche su bolsa anti humedad, Esta muy bonito, lo recomiendo, cuando lo compre estaba un ((poco mas caro)) HOY... PRECIO CALIDAD DE LUJO. MUCHAS GRACIAS.

Es una aparato perfecto para electrónicos amateur y profesionales , siempre he tenido osciloscopios analógicos de doble trazo , pero nunca con una tecnología tan avanzada , con gran cantidad de usosy una frecuencia de muestreo tan alta , es una maravilla , espero que su fiabilidad este de acuerdo conla calidad del producto

Tiene un excelente precio para los 200MHz que ofrece, viene bien embalado con lo necesario para colocarlo y revisar todos los circuitos, sin duda lo recomiendo.

Las opciones digitales y el ancho de banda y la frecuencia de muestreo menpareces muy buenas con respecto al precio.

Excelente producto, lo estoy aprendiendo a utilizar pero hasta ahora genial, lo estoy utilizando para medir potencia en circuitos RLC y funciona muy bien. Espero aprender a sacarle provecho a sus muy amplias funciones. Me ha gustado mucho.

Insegno laboratorio di telecomunicazioni ed elettronica, ho acquistato questo oscilloscopio per motivi soprattutto amatoriali, prima su tutto il ferromodellismo. Ho fatto molte ricerche su oscilloscopi similari con prezzi svariati fino ad arrivare a qualche migliaia di euro. Mi serviva un due canali e una buona banda 200 MHz, la scelta è caduta su questo tipo della Siglent. L'oscilloscopio si presenta molto bene, ampio display e rivela subito una struttura di alta qualità. Su you Tube l'ho visto lavorare assieme a un colosso della Rohde&Schwarz e questo è indubbiamente un riferimento importante. E' pratico, semplice da usare, avendo anche la possibilità di selezionare le varie voci in lingua italiana.Veloce nelle impostazioni delle numerose funzioni, un rapporto qualità prezzo senz'altro molto elevato. Ho lavorato con diversi oscilloscopi digitali, hp, Rigol, Tektronix, Hameg , ma questo li supera decisamente per la semplicità d'uso. Le sonde vanno compensate e questo non è un problema, inoltre è calibrato con certificazione e con dicitura sul retro. Lo consiglio vivamente a tutti, professionisti e non , anche a chi volesse iniziare un'attività sperimentale di laboratorio. Un centro di assistenza si trova vicino Padova molto comodo. La consegna è stata veloce, in pratica l'ho ricevuto con cinque giorni di anticipo, il voto è d'obbligo a 5 stelle.

por características tecnológicas considero la mejor opción de Osciloscopios de bajo precio, buena calidad en pantalla (brillante) , botones , carcasa, si te gusta la electrónica o reparas equipos electrónicos es una excelente opción.
