To provide a little more detail, the output/function generator can be in one of three modes: - high (1Meg Ohm) impedance - source voltage - source current If there is a source function, you can provide: - DC level - repeating waveform (n samples that repeat forever, where repeating happens in the host side library) - arbitrary waveforms (where the application provides data, when the data underflows, hardware stops, and must be restarted by the application). > The PPS support is currently based on setting the target output > voltage/current > via the configuration API.

Fixed "function generator" are a little different than an arbitrary waveform generator. It is pretty easy to make a sine/square/triangle/etc wave, and repeat it. It's a little more difficult to AM/FM modulate the sine wave, and stream the output. It's not just the API, but also the GUI can become pretty complex if you aren't careful. > > As soon as a few more units get off the manufacturing line, I can send > > some over to anyone interested -- Any thoughts on how to add a SMU (in > > a generic sense, and the M1k specifically) to sigrok? > > I'd be interested in getting one and working on this.
