Top class! I have a couple of things to add if you haven't already found them. The arbitrary waveform transfer is actually - :aX0,n2,.........n64<CRLF> :aX1,n65,n66........n128<CRLF> . . :aXF,n.........n1024<CRLF> where X is an arbitrary waveform store from 0 to F (Hex). There is an OK<CRLF> returned between each block when transfer is successful. The Sweep time message is :s5tn from trial and error. Regards, Chris |

Would be nice if the protocol for the FeelTech signal generator can also be reverse engineered, or has somebody already confirmed that they are identical? |

Here is some eval of the generator performance. Regards, Dana. |

| danadak:
The pics were all probed with 10X probe, 1M, 12 pF. Also a 10X 10M 14.5 pF probe. When looked at with 50 ohm scope termination, straight short coax, not much changed in terms of ringing, distortion. I looked recently at narrow pulse, low duty cycle, at 1 Mhz pulse looks like slew rate limiting of output amp. At 6 Mhz just 1.5 V, lots ringing severely distorted. Regards, Dana. |
