Connectivity issues

I am trying to connect my PC to a E5071A ENA Series Network Analyzer, but when I do it, the Fail LED on my GPIB cable turns on. My objective is to control the VNA from Matlab, using the Instrument Control Toolbox, but when I click on the scan icon, it doesn't find the instrument.

I found out Matlab offers a support package called "Instrument Control Toolbox Support Package for Keysight IO Libraries and VISA Interface", but I can't download it yet, so I was wondering if installing this will solve my problem.

I also tried to find any kind of drivers for the VNA in its corresponding Keysight page, but I can't find any (except for some printer drivers).

Any suggestions?

No one else has this question

Update: I have downloaded the 2019 keysight IO library suite, and I still fail to connect the device.

The GPIB cable LEDs now light up correctly (all of them should be on), but when I scan the intsument through the intrument control toolbox of Matlab, I can't find the VNA.

I also tried the conexion expert that comes with the IO libraries, but that program fails to detect the VNA too.

Hi,

Check the GPIB settings: must be in talk / listener mode (SYSTEM, MISC SETUP. GPIB CONFIGURATION)
If you make a change, you must restart the instrument.

If everything is set up correctly, try adding an instrument manually in Connection Expert instead of an automatic search.

Hi,

The GPIB settings were already in talk/listener mode.

How should I add the instrument manually? I click on the "+Add" option but

it asks many things that I am not sure how to fill in.

Thank you for your help,

Aingeru

OK, when you used ADD+, first set the GPIBcard address, if you have only one, address is 0 (GPIB0). Second, enter primary gpib address of your VNA (example: 16). Nothing to enter for secondary address. AUTO-IDENTIFY checked...software will send *IDN? to verify connection.

I can't find those settings you are talking about. I'll attach 3 pictures

to show you what I see.

The first one shows up when I click "add+". I don't know if I have to

choose GPIB-VXI interface, or Remote GPIB interface.

In the second and third, I show you what I see when I click in each of the

GPIB options.

+ADD

GPIB0 if you have only one gpib card

Primary address (your VNA address): in this example 16

Secondary address = NONE

Ckeck AUTO-Identify

Test connexion: if everything is OK, the word "VERIFIED" appears
