14:46 <Guest32> joshua_: the calkit is a usb tmc class device. VID: 0xf4ec PID: 0x1600

14:46 <Guest32> SCPI commands to do the actual switching:

14:46 <Guest32> "SET:PORT OPEN,A",

14:46 <Guest32> "SET:PORT SHORT,A",

14:46 <Guest32> "SET:PORT LOAD,A",

14:46 <Guest32> "SET:PORT ATT,A",

14:46 <Guest32> "SET:PORT OPEN,B",

14:46 <Guest32> "SET:PORT SHORT,B",

14:46 <Guest32> "SET:PORT LOAD,B",

14:46 <Guest32> "SET:PORT ATT,B",

14:46 <Guest32> "SET:PORT OPEN,C",

14:46 <Guest32> "SET:PORT SHORT,C",

14:46 <Guest32> "SET:PORT LOAD,C",

14:46 <Guest32> "SET:PORT ATT,C",

14:46 <Guest32> "SET:PORT OPEN,D",

14:46 <Guest32> "SET:PORT SHORT,D",

14:46 <Guest32> "SET:PORT LOAD,D",

14:46 <Guest32> "SET:PORT ATT,D",

14:46 <Guest32> and is read like this:

14:46 <Guest32> "FL:DATA:READ:STARt"

14:46 <Guest32> "FL:DATA:READ? 1024"

14:46 <Guest32> the cal data is stored in a a zipped csv.

14:46 <Guest32> #A,B,C,D,T_AB,T_AC,T_AD,T_BC,T_BD,T_CD,CF_AB,CF_AC,CF_AD,CF_BC,CF_BD,CF_CD

14:46 <Guest32> readout csv:

14:46 <Guest32> "FL:DATA:INDEX 0" # no clue which index is correct

14:46 <Guest32> "FL:DATA:READ? 1024" # loop until done, last block is smaller, no clue where total size is coming from

14:46 <Guest32> As there are too many unknowns I stopped working on this until I get access to a siglent calkit to readout the header/csv. No clue about the attention between the ports.

14:49 <Guest32> well... that didn't really workout... https://nopaste.net/#XQAAAQAHBQAAAAAAAAA1G8rNIqiwTUHpBBPtMB9xWkQmGwemgb30oU2Q0qjha47dDNtN/S+CtOcnZpnLfgfGhJyA4K+fIV/CJhbY/j/cAFu7Wg06ZF32YiVai2Y1Nrw0mpcZ7Qlu4cJ4l8lH4xcYrU4euVMyQtveRNzQ+oM5IG72AiRcsZRS/J1wPQCK15E0qOMLF1SkfraXspe/xDECA3qPnjS+xGHIR1IS7ubFkw10A7uLohpeidFOsmF+08uV+PmVri2U3Y51K3B3Zb00NKzeQIlaofEDplK

14:50 <Guest32> I have some patch for some old librecal fw to add usbtmc, but was to lazy to actually figure out what is missing by try and error. I think it is to much unknown to solve it without a ecal dump.

14:55 <Guest32> well. ticking the box for "no upload" isn't really doing me any favours either. so lets try again.

15:01 <Guest32> I do have a ghidra project, but I don't think sharing is too helpful. entrypoint for me was ext_dev_usbtmc_session_t and ecal_dev_siglent_t

15:02 <Guest32> (I try to read the log and answer in a more timely fashion than last time ;))
