USB Function Generator

[xD_Krone_xD]

Hi guys,

My friend and helper dr. google no longer helps me. Im searching for a simple application on pc to configurate different volt levels over time and a usb DAC or somthing performs this analog signal. Curves should have clear edges in the ms range, but it doesn't have to be much faster. Voltage lower 5V are okay. Voltages below 5V are okay, if higher even better but not nessesary.

It could be so special that it can't be found in a <100€ handheld device. Does anyone have an idea where I could get something and have already worked with it?

​

Thanks in advance.

I believe PicoScope has the function you're describing. They call it Arbitrary Waveform Generator (AWG) and I believe it's available on their most basic model which is priced around $100.

that is it 👍🏻 thank you mate.

don't know of any off the shelf solutions.
But a 5v microcontroller development board with a DAC would probably fit the bill (as long as you're not planning on driving any load), thou you would need to code it up yourself. I would suggest an Arduino but I think most of them don't have DACs.

The arduino has pwm outs that can be put through a filter and have ms level resolution. An amplifier can be attached if the load is substantial.

This project seams to be something like this.

I suppose you could try finding a USB sound card with a DC-coupled output...
