Can I control E4990A with a program installed on the embedded PC? How should I configure the instrument?

Frequently Asked Questions (FAQs)SummaryThis article shows how to configure E4990A to control it from its embedded PC where you have installed a programming environment, for example Matlab.QuestionCan I control E4990A with a program installed on the embedded PC? How should I configure the instrument?AnswerYes, you can. To do that, you can use the localhost capability to control the E4990A from the embedded PC: once you've opened the IO libraries on the embedded PC, you must add a LAN instrument writing localhost in the "Hostname or IP address" field. Then you can chose a protocol to communicate and select "Test this VISA address": The instrument VISA address could be “TCPIP0::localhost::inst0::INSTR” or "TCPIP0::localhost::5025::SOCKET" or "TCPIP0::localhost::hislip0::INSTR" depending on the Protocol you are using. With E4990A it's better to use the SOCKET protocol and you must configure it both in the IO Libraries (as shown above) and in the instrument. To do that: enable Lan on your E4990A selecting System > Misc Setup > Network Setup > Enableenable SOCKET selecting System > Misc Setup > Network Setup > Mode  > Socket You can test instrument connection sending the "*IDN?"  SCPI command. It will return the instrument information. Finally, in the programming environment you would like to use, you'll address your instrument using the above verified VISA address (for example TCPIP0::localhost::5025::SOCKET) to connect to the instrument.
