Instrument Control (iC) allows to control (scientific) measurement instruments by processing a list of text-based commands that define the measurement sequence. These commands are in an intuitive format to provide great flexibility and allow easy adaptation to various measurement needs. The funcionality of iC can be extended with minimal programming effort or by defining new commands in a text file without any programming. iC supports GPIB, RS232 and USB. Tutorial videos show how to use iC.
