Van néhány probléma, és nem tökéletes, van egy DC ofszet a kimeneten, és nagyon alacsony kimeneti kapacitással rendelkezik. A kimeneti impedancia túl magas ahhoz, hogy bármit megtöltsön, de mint alapvető alacsony teljesítményű jelforrás, rendben van. Erősen javaslom, hogy épít egy áram vagy erősítő, hogy menjen végig oldalán, hogy több energiát. Az ár ez egy nagyon jó tanulási eszköz, ha van egy oszcilloszkóp, és mivel beállítja a funkciót gen vakon nélkül hatály ez nem olyan hasznos. Akkor is használja a telefont a funkció gen, de ez nem rendelkezik az az előnye, hogy jobb frekvencia tartomány, és valószínűleg jobb emelkedés / esés alkalommal, hogy gyors. Megvan a maga helye, de ez nem egy precíziós intrsument, csak egy hobbi tanulási eszköz, próbálja meg használni a kondenzátort sorozatban a kimeneten, hogy távolítsa el az eltolást

It has some issues and it is not perfect, it has a DC offset at the output and it has very low power output capabilities. The output impedance is too high to power anything but as a basic low power signal source it is fine. I highly suggest building a current or power amplifier to go along side it to get more power. For the price it is a really good learning tool if you have an oscilloscope and since you are adjusting the function gen blindly without a scope it is not that useful. You could even use your phone for a function gen but this does have the advantage of better frequency range and probablyt better rise/fall times making it fast. It has its place but it is not a precision intrsument, just a hobby learning tool, try to use a capacitor in series at the output to remove the offset

PB is good quality and there is no major problem mouting it Some gotchas : * The square output is not modulated by the amplitude pot, it will always be maximum. I searched a long time for that. * The bolts are BELOW the pcb, that's why the internal screws look too short. They are just there for alignment, The PCB is hold back by the pots being sandwitched by the case (see pics, i used nylon screws but they are ~ same size as the provided ones) * you can add a led + ~ 1k resistor a tthe top of R3/R5 (R3 is VCC, R5 is GND) * The pots are not all the same, one is 100k, the 2 others are 50k

Szép darab, gyűjtött, kiérdemelt. Rengeteg van az interneten, hogyan kell alkalmazkodni és fejlődni. Miután befejezte, tiszta arcüreget kapott. A finomítás után kiderülhet, hogy egy elég tisztességes amatőr univerzális generátor.

Хороший набор. Собрал - заработал. В интернете много написано как настроить и улучшить. После доработки получил чистый синус. После доработки может получиться довольно приличный любительский универсальный генератор.

Great purchases, order placed and delivered 15 days later at the Post Office, congratulations to the BG team for the good work. It arrived in a simple package with padding protecting some assorted items, and in perfect condition. After opening and photographing, it took me a lot of small items in one purchase and I didn't have much time available, however, I did some tests and observations. A good DIY Kit, the components are in separate packaging, it seems to be ready to be assembled without having to buy extra parts on the market or search for diagrams on the internet and print. I liked it and will be assembling soon, as soon as I have time available. Ótimas aquisições, pedido feito e entregue 15 dias depois na agência dos Correios, congratulações ao time da BG pelo bom trabalho. Chegou em uma embalagem simples com acolchoado protegendo alguns itens sortidos, e em perfeito estado. Após abrir e fotografar, demorei pois foram muitos pequenos itens em uma compra e não tive muito tempo disponível, porem, fiz alguns testes e observações. Um bom Kit DIY, os componentes estão em embalagens separadas, parece estar pronto para ser montado sem ter que comprar peças extras no mercado ou buscar esquemas na internet e imprimir. Gostei e irei montar em breve, assim que tenha tempo disponível.

Pont úgy jött meg, ahogy ígérték egy hét alatt itt volt. Ennyi pénzért a hülyének is megéri, hát még nekem. Összerakni egyszerű mint a faék. Játéknak meg jobb mint a LEGO. A tápegység nem tartozék.

Assembly is really easy and done within 15 minutes. Waveform output of square and triangle work fine, sine wave is more tricky. Supply voltage should be 12...12.5 V. Not all frequencies are stable and only a range of the amplitude yields an undistorted sine wave. Keeping this in mind, it works quite well and is nice for quick demonstrations or to put it in your pocket.

Great piece of kit. Very usefull for beginners. Reasonably accurate at low frequencies. The assembly is simple and funny. Highly recommended!

Short notice in English language. Very easy to assemble. See the pictures for reference. The height of the box is quite limited, maintain the capacitors as close as possible to he PCB else you will be unable to close the box. Also, the power socket (JK1) and the variable resistors R2, R7 and R8 emerge too much below the PCB, and you must cut a small part of their pins. For the variable resistors and the 2 sockets JK1 and P1, as much as possible use a larger tip on your iron solder or raise the temperature by 10 to 15 degrees Celsius because of their thermal mass. Place the jumpers for the frequency range and the signal type as needed. Powered and worked fine.
