Hi, Bert, Thanks for your suggestion. I agree that SR_DF_META packet is a proper way to send it.
My device like usbee dx is not a real usbee dx. it is made by myself from PCB to plastic case. and probes are cheap Chinese ones like other clones. But it works well on Windows without any problem, especially without any delay between digital sample and analog sample of the same signal. So I think it works like real USBee DX. But I heard that some clone has some timing issues from a forum. I think it's due to different parasitic capacitance of digital and analog lines. I heard they used different parts in analog and digital lines, something like OP-AMP and voltage protection diodes. And even different PCB artwork can make it. I don't have those clones so I'm not sure. but I think analog signal delay value could be a user-defined value. So like other configuration key, this might use the same way. If someone has a clone, please check and let me know it. On defining configuration key, I think already-defined SR_CONF_TRIGGER_SLOPE key is proper for trigger slope of oscilloscope, This value is bound to uint64_t type and shown as integer value on pv's dialog box. I think this value could be changed to more readable value(rising or falling) for usual users. Is there any reason to be shown as integer value?
