Hi przemek
Thanks for the superb work on the manual. 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.

Looking at the ringing, how did you probe it?
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.
