MSO64B matlab control over USB

Hi,

I've had issues connecting to the MSO64 via USB in Matlab using the instrument control tool. I see the resource USB0::0x0699::0x0530::C050282::0::INSTR but I receive a connection error, could not open VISA object.
It works well using TCPIP.
Is it some kind of USB driver issues? I've tried different VISA (keysight, NI, Tek) but nothing works.
I would appreciate any help I could get.
Thank you.

HI Pascal. Just a couple of clarifications before I dig further. Are you using a MSO64 or MSO64B? Also confirm the firmware version you are using? ( latest is 1.44)  Does the scope have Windows or Linux OS option?
regards

Hi

I did a quick test with Matlab 2020a, Ni-VISA and a MSO44. I was able to connect.

The only thing I see unusual is you have an extra "::0" in your identifier.

Here is what my string looks like:

g = visa('ni','USB0::0x0699::0x0527::C033013::INSTR');

Can you give this a try?
 

Hi 
I found the MSO44/46 also have issue when connecting via USB, it seems the "CLEAR" command would make them stop response. but via LXI, they seem working well. even if I was able to capture data from the scope, it is easily lose communication when connecting via USB.

Hi Blair,

Thank you for your suggestions.
I tried the address without the zero, but couldn't connect either. Error using icinterface/fopen
Unsuccessful open: Could not open VISA object. Use INSTRHWINFO for a list of available configurations.
I'm using an MSO64B with firmware 1.44.3.433 (I think the latest one?), it doesn't have Windows or Linux on it.
I also find that Matlab  Test and Measurement Tool takes a long time to scan for USB instruments. 

instrhwinfo('visa') returns     InstalledAdaptors: {'agilent'  'keysight'  'ni'}
Could it be an incompatibility between the different visas that causes the problem?
I'm attaching an screenshot of the Keysight connection expert, I also cannot connect to the scope using it.
Using tcpip would be fine, but the laptop I'm using doesn't have a ethernet port.

Thanks again for your help.
Regards,
Pascal

Hi Pascal.
In order for a deeper discussion and collection of  details you may not want to share in an open forum I would suggesting submitting a Support ticket at tek.com. This will get you a direct link with a Tektronix engineer.
