How to connect to oscilloscope using MATLAB with Linux Ubuntu as operating system

I am running Linux ubuntu 22.04 as my operating system with MATLAB 2024a. I am trying to connect to a HDO9104 Lecroy oscilloscope using Instrument Control Toolbox via TCP/IP. However, MATLAB is unable to detect the oscilloscope.

Hi @Howe Li,

Before proceeding with MATLAB, ensure your LeCroy instrument is configured for remote control:

1. On your LeCroy instrument, select Utilities > Utilities Setup, and choose the Remote tab.
2. Ensure that under Control From, the TCP/IP button is selected. Your instrument’s IP address is listed in the TCP/IP panel of the Remote tab.

You can verify connectivity to your instrument by issuing the following command from MATLAB:

!ping <instrument-IP>

where <instrument-IP> is the IP address of your instrument.

Once you've confirmed the network setup, please ensure you have the MATLAB Instrument Driver, which consists of custom drivers specifically designed for MATLAB. If not, you can download it from this FileExchange portal: https://www.mathworks.com/matlabcentral/fileexchange/12862-lecroy-oscilloscopes-matlab-instrument-driver.

There’s another one from Teledyne that you may also want to try: https://www.mathworks.com/matlabcentral/fileexchange/84144-instrument-driver-for-teledyne-lecroy-scopes-in-matlab.

Once you've confirmed that, you can try running a simple example found here: https://www.mathworks.com/matlabcentral/fileexchange/22627-lecroy-oscilloscopes-matlab-example.

To troubleshoot connection errors, follow the steps provided at these links:

If the connection is established but you’re unable to read data, please refer to the troubleshooting steps here: https://www.mathworks.com/help/instrument/tcpip-client-warning-unable-to-read-any-data.html.

Hope this helps!

I have followed the instructions to get the scope IP and tried pinging. So far no connection.

@Howe Li,

We have determined that the issue is connection-related—your PC is not detecting the hardware.

Please refer to and follow the troubleshooting and resolution FAQ on the Teledyne website: https://www.teledynelecroy.com/support/knowledgebase.aspx?docid=487&typeid=1&capid=176&mid=897&smid=

Additionally, there are two connection methods available: remote and direct. If the above resolution doesn't work, you might try switching to the other connection method.
