If you are concerned about things like accuracy, jitter, rise and fall time, etc.. then this generator is not for you. It should not be used as a calibration standard... it's not that accurate. The display is a standard 16x2 LCD with a green backlight. The output can go as high as Β±10 volts (there is an internal voltage generator). The output filter really does nothing. The zero offset control works, but is rather useless.This little signal generator consists of an Atmel ATMega48v microcontroller driving an R2R ladder (8 bits) to generate the waveforms. The waveforms are precalculated and stored in the microcontroller's flash memory. A small loop written in tight assembler cranks the samples out to the R2R ladder to generate the signal. The rest of the code is ordinary C. You could easily add to the waveform library if you wish. Just generate it, store it to flash and add to the menu. The ATMega48v is clocked at 30.0 MHz. (!) which is way above it's spec, but it runs just fine and stable as ATMega's do. If you are an Arduino tinkerer and have a compiler and ICSP programmer, there is a third party program that you can program into an ATMega328p chip and improve the functionality of this generator (one handy feature being storing the last used settings in EEPROM so that the generator comes up the way it was last set. The buttons are also debounced much better). Search for "Alternate Firmware for FG-100". You will need the ATMega328p because the Mega48v doesn't have enough memory to add anything to the stock code. The 328 and 48 chips are, of course, pin compatible.All in all, this generator works great for what it is, and it's design makes tinkering with it or adding to it easy. It will be a both a useful tool and a fun platform to tinker with. I bought two of them, one to use and one to experiment with. I highly recommend it. Lots of fun!
