I'm the user of Agilent’s E4980A precision LCR meter. Now i 'm doing the final year project that to develop a friendly-user software so that the user can operate the instrument through the computer.So far i had successful to connect and get the result from the instrument by using the visual basic programming language.However i failed to set the variable frequency.As we need to key in the value of frequency into the SCPI command ":FREQ:CW <numeric>" only can change the instrument's frequency.Hence,is it got other ways to solve this problem?
