Monday, December 30, 2013. Difference between SCPI commands *WAI, OPC? Spent some time trying to know the inside out of *WAI, OPC? And OPC, didn't work out quite well though. There are conflicting explanations regarding both *WAI and OPC? In the case of *WAI, some say it will hold the instrument only, others say it will hold the whole bus; In the case of OPC? Maybe part of the reason is that it's up to the manufactures to implement these commands and each has its own liking? Although *WAI stops the analy...

Technical Notes: June 2011

Friday, June 3, 2011. There are two terminal types for gnuplot that I know of, one is win, the other is wxt. Wxt has more functions than win and is therefore preferred. To make sure octave uses wxt instead of win, simply set the environment variable GNUTERM = wxt by "right clicking My computer - Advanced - Environment Variables", remember to restart octave. And it is possible that the plot terminal might freeze for some reason. One work-around to this is to add the following commands.
