Hi All,
I just bought my first oscilloscope and my eyes are being opened to the world of electrical T&M. I recently developed a CMOS board to decode encoder signals from an industrial robot I am refurbishing as a hobby. One thing that would have been helpful is to inject a RS422 differential signal bus into the board emulating the encoder signals to help validate the functionality of the board. I have seen arbitrary waveform generators, but these look like single or dual channel devices mostly for analog design (although I'm sure their use extends into the digital realm). For my particular application, I would have wanted to inject 3 synchronized channels with various waveforms (a parallel bus). How do designers accomplish this task without building custom hardware. I saw a high end scope that came with a 4 bit pattern generator, but what if you needed 8 or 16 channels?
Thanks - just curious.
