Akbar VIP1AE27/07/2021It 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

fx123 VIP3FR18/02/2017PB 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 50kComments (0)Show Original -

0A:Hello,I bought the disassembled version and I did the assembly without any problems, all the parts are of quality and it worked perfectly. I believe the price difference is between those sold already assembled and those that are not assembled.Answered by alexandreeckel1969 on 02/07/2022Helpful (0)

0A:It is best to separate what we know from what we don't know. It has the same name, but it is not the original, it is what we know. Does it perform the same functions, has the same efficiency? It is what we do not know. Please experimentalists, answer these questions.Answered by TonBG248126253 on 27/04/2021Helpful (0)

0A:Try to slightly move the position of some components by gently pushing them apart with fingers. Make sure you trimmed the component legs close to the circuit board tracks, after soldering. Examine circuit board tracks for solder bridges or crystallised dry joints. Let us know if you managed to solve the issues.Answered by BigMac on 04/07/2021Helpful (0)

0A:It is a learning tool, has no precision, even using a scope the adjustment is difficult, modifications can and should be made to facilitate its use, high impedance audio output and very low power, a pre amplifier with insulation and proper voltage level should be constructedAnswered by TonBG248126253 on 30/12/2021Helpful (0)

0A:The kit generates waveforms with a defined amplitude. You have to match the correct amplitude, frequency, waveform and impedance of your own transductor. The kit should easily reach 100 kHz, but the waveform tends to degrade above that frequency.Answered by lmorelli on 24/01/2021Helpful (0)
