I have MSO7034B oscilloscope and I'm trying to connect it to my laptop running Windows 7 SP1.

I installed IO Library Suites 2018 Update 1.0 (IOLibSuite_18_1_23218.exe)
Installed IVI driver for MSO7034B Version 1.3.24.0(driver_ivi_Agilent546XX_1_3_24_0_x86.msi)
I set the I/O option in Utility menu in the oscilloscope to USB option.

When I open the Keysight Connection Expert, an instrument is detected but there is the red cross mark on it. It is not connected. I'm not sure what is the problem.

I'm attaching the screenshot of my Keysight Connection Expert. Kindly help me in solving the error.

Thank You in advance.

Hello Sumesh.1988,

Do you know if the "Found New Hardware Wizard" opens up on your laptop when you plug in the USB from the scope? There are certain drivers that need to be installed and this wizard should be able to get them for you with all the defaults selected being fine.

Check out this link on our website: Using a USB connection | Keysight (formerly Agilent’s Electronic Measurement)

Let me know if you have any questions.

  Hello KSuiker,
  "Found New Hardware Wizard" did not pop up. I checked Device Manager and I could see IVI driver is installed properly. I'm attaching the screenshot below.

Seeing the same thing on a MSO7104A. But I blew it off because I was able to send and receive commands using the Interactive IO despite the red X.

My main task is to write a C# code to download power trace from the oscilloscope.

I tried running the program given in Keysight "Using the IVI-COM Driver for InfiniiVision" pdf under section "Visual C# Quick Start". The link for the pdf is https://literature.cdn.keysight.com/litweb/pdf/54695-97017.pdf?id=1759305

When I run this code I get the following error

Somewhere I read that logical name can be set using Connection Expert tool. Hence I'm trying to connect Connect Expert with the oscilloscope.

Any suggestions or hint to achieve my main goal "C# code to download power trace from oscilloscope to PC" will be really helpful.

Thank You very much.
