Is there any other real world use for one? --- End quote --- Absolutely. You use it to put complicated looking Lissajous patterns on your scope to impress visitors/your spouse. --- End quote --- :-+ I don't have one. Just a pulse generator which gets seldom use. Every project I have done has relied on itself to generate all necessary signals starting from the wall socket and downstream from there. Wait a minute - I just made an audio oscillator of high purity to test possible audio projects, so there's that. |

I am always finding uses for my generator. Just today I wanted to quickly do some motor control work and used it to generate a PWM. Saved a lot of time having to get a micro out and program it etc. |

Perhaps a more interesting question might be 'real world use of two function generators'. I was bemoaning the fact that I have three function generators but wish I had an arbitrary waveform generator. But perhaps I can combine two of my function generators to create one. I recall back in the early 1960s I worked for a company that made a function generator. It was housed in perhaps two or three six foot racks, all tubes of course, with many 10 turn potentionmeters to set various points on the desired waveform. I never used or worked on this device but found it fascinating. I do believe that with use of some of the rear panel auxiliary inputs I can make a staircase wave or something like it. Any ideas? I haven't given this much thought yet so maybe I can answer my own question. |

The power supply adapter is garbage. Throw it away and use a decent adapter, or put a simple block transformer + LM7805 in the thing itself. Plenty of room. On low amplitude it gets a bit noisy. The signal is generated by a 12-bit ladder DAC on the output of an FPGA. ... --- End quote --- You have damn near convinced me that I should have one on my bench!! --- End quote --- ...and I did!
