Ethernet with e4438c %3F

[Bouyakaz]

Hello everybody,

I want to know iuf it's possible to command a Agilent e4438c ( Vector Signal Generator ) with labwindows through an Ethernet connection. I find drivers for GPIB connection on agilent website but it will be better with Ethernet.

So is it possible with Labwindows to pilot it in ethernet ?

THANKS.

Look at the datasocket examples.

If the Ethernet port can be used for programmatic control and the instrument is VXI-11/LXI compliant, you can just use the IVI driver as is. Have you tried or have you contacted Keysight?

Yes, the ethernet port is VXI-11/LXI compliant, i will look at the IVI dirver with more precision. It's a little difficult for a beginner because there is not a lot of example on internet. I will contact Keysight to try to find the best way to connect the e4438c.

Thanks

Hi,

I configured my system and it communicate well with other utilities like MAX.

But, when i try to run my labwindows program, with SICL language, it doesn't work, it seems to communicate but not to follow the other instruction.

Some command of my program :

char* instOpenString ="lan[20.250.11.3];

INST id=iopen(instOpenString);

if (!id)

{

fprintf(stderr, "iopen failed (%s)\n", instOpenString);

return -1;

}

 iwrite (id , "*IDN?\n" , 6 , NULL , NULL );

 itimeout(id, 2000);

 iread ( id , buf , 200 , NULL , &actual );

 iclose(id);

I have no return reponse so i think the connection works well, but buf and actual never change, it's like if it didn't read anything.

SICL? Really? Why post on a CVI forum? Go to Keysight or use CVI with the IVI driver and follow the examples that come with CVI.
