I do use python for everything up to now. It's just a little frustrating that none of the open source projects have very complete SCPI command coverage of the features for some of the less common instruments, like the Keithley 2700 DMM/Scanner. For example, nothing I've found has implemented the command to check the EEPROM relay closure count on the cards. I would have expected that to be straightforward, but just issuing the command times out so there must be some setup sequence I'm missing. It would be nice to just have that basic functionality working out of the box with something like the vendor supplied software (Kickstart in this case).
