Siglent 1104x-e and ethernet use
(1/1)
Gibson486:
I am trying to talk to the Siglent 1104x-e over a direct ethernet connection (ie connect ethernet directly from laptop to oscope) with pyvisa.

Here is what I have done thus far....

I changed my ethernet ports IP to 192.168.70.XX. My wireless is 192.168.20.XX

I set the mask to 255.255.255.0

On the scope, I set the IP to 192.168.70.XX+1

and I set the mask to 255.255.255.0

I can ping the oscopes manual IP....

I then run my pyvisa script.....and I tell it to list the resources the the resource manager found, but it finds nothing (this is how I usually find it over USB).

Maybe I need to specify the gateway address (not sure what that does)? I changed it on the scope to 192.168.70.1, but windows does not let me set the gateway address.

Did I forget to do anything or did I just do something wrong?

edit: I entered the scope's IP address into a browser and it leads to the Siglent control page....so it looks like it is a pyvisa issue?

Solved...

Had to download NI-VISA to create the driver.

For those not conversant with this IP stuff it can be simpler to just connect the scope to your LAN switch and let DHCP do it's thing to provide the Gateway, Subnet and assign an IP to the scope.

Each time you connect DHCP if left set to ON will assign a new IP to the scope for which you'll need to dig into the LAN settings to find this IP or we can go about saving it.

My way FWIW:
With DHCP set to ON let the scope negotiate the correct settings then turn DHCP to OFF and bump the IP's last digits higher to where there is little chance of an IP clash and then Save the IP.
Eg. DHCP returns 192.168.0.11 save as 192.168.0.101 < which becomes your scopes permanent IP address for you to access in a moment with a PC web browser to use the scopes internal webserver.

Whatever/however you want to work with the scope over LAN will use this custom IP you have set and saved and at a level where you'd be unlikely to ever have an IP clash with another device.

Oh yes this too if you need use something other than the inbuilt webserver and the scope remote control or SCPI command page.
NI-VISA is a large bloated thing sometimes just needed for the LAN and USB connectivity drivers however we can trim it down some by just installing the NIVISA Runtime package, ~25% of the size of the full install.  :phew:

hahaha...Yeah, I died a little inside when I downloaded NI-VISA. That being said, it did say the programming manual that NI-VISA needs to be downloaded. I just figured that since it did not need it in with USB, it would not need it with Ethernet.
