ICQUANZX XR2206 High Precision Function Signal Generator DIY Kit Sine/Triangle/Square Output 1Hz-1MHz Adjustable Frequency Amplitude

One of the worst product, this won't work properly. Please don't buy this

As a soldering kit this thing is pretty cool. It was fun to put it together, no missing components. The kit comes with a useless printed copy of the circuit tough, if you want to see a good tutorial, search YouTube for “DIY AC Waveform Function Generator Kit - The Learning Circuit” from Element14.Now, when it comes to using it as a signal generator, it's alright but not amazing. You won't know the exact frequency or amplitude of what you're sending out, which can be a bit of a bummer. The square wave is fixed at a 50% duty cycle too, so no tweaking that. The sine wave maxes out at about 5.6V peak to peak and starts to clip, but for the price, I don’t complain. Just know that it's more for playing around than doing any more serious experiments.I've tested it out, and at 500 Hz, the signals are pretty clean. Push it to its max ~1.2MHz, and you'll see some quirks with the sine wave and the square wave's ramp-up. So, it's decent for casual use, like if you're messing with a simple amp circuit or doing a quick PWM prototype.It'd be awesome if you could adjust the square wave's duty cycle. But as it stands, it's a decent, fun little project that gets the job done for simple stuff.

Basilare nella progettazione ma funzionale. Durante l’assemblaggio non ho riscontrato alcuna difficoltà, certo le istruzioni allegate sono pressochè inutili e illeggibili ma basta una breve ricerca in rete per trovarne migliori, anche molti tutorial passo passo. I componenti sono pochi ed in poco tempo si salda il tutto; però sono sfusi e non etichettati quindi bisogna armarsi di tester per individuare le resistenza e stare all’occhio sul valore dei condensatori. Tutto facilmente superabile con un po’ di pazienza. Sono rimasto piacevolmente stupito dal risultato e dalla qualità dei segnali, certo non perfetti e se si esagera con l’ampiezza non reggono, ma per quel che costa è veramente stupefacente!

Bonjour, j'avais besoin de dépanner un ampli audio et pour cela il faut un générateur sinusoïdal 1000htz1v si possible or ce petit générateur a base d'un XR 2206 remplit bien ces fonctions et bien au cela caron peut utiliser des signaux carrés et triangulaires réglables en amplitude et en fréquence jusqu’à 1Mhtzle montage du kit est réalisé facilement en 45mn testé a l'oscilloscope les signaux sont stables et précisfonctionne parfaitement pour une dizaine d'euros ça vaut la peine d'en avoir un...content de cet achat...Bien Cordialement JP..33..
