content: I recently acquired a power supply with LXI support. But I am clueless as to what to do with this. No software was supplied so I'd need external software and the little I hear about this stuff is expensive + hard to use. Are there any cheap and practical ways to use this functionality ?

content: Hi Simon, how about a little bit more info, brand, model...LXI is standard to communicate with instruments via Ethernet. Usually you just send normal SCPI commands and instrument obeys... or not :-)You can use Python with libraries, Scilab, Octave.... Or Labview, MAthlab.... Or software from manufacturer if there is one.Usually you use to automate some measurement procedure, testing process or something... Or calibrate.Generally for repetitive and boring stuff while being sure it was done exactly as it should be.So that's general overview. For more details, provide more details..EDIT:I see it is TTi, what model? TTi is good brand, they have good manuals with full SCPI command set to use...Regards,Sinisa

content: You can read theLXI specificationsand write software to control it.AIUI there are generic commands for standard functions on conventional instruments, so basic operation should be reasonably device-independent
