Win7update Agilent33250A problem

[sgorumlu]

I have windows update problem.  

I downloaded drivers using Labview (Getting started window > Tools > Find Instrument Drivers) from NI certified drivers and installed them. Also, i downloaded Agilent IO libraries suite 15.5 to provide connection between GPIB and computer (15.0 did not worked in Win7 which was supplied with 33250A and 15.5 is worked). After i plugged the GPIB/usb connection to computer, i see that GPIB is recognized and green led light is observed. I reached the device using drivers and set the parameters properly.

I recognized that win7 updated itself and from that reason, somehow, i see the connection between GPIB port and computer, but i can not initalize  the device or set the parameters (frequency, amplitude, etc ) using drivers downloded from the NI website. I reinstall the drivers Labview software but it didn't worked.

Win7 update caused this problem, how can i set parameters (of course write new blocks) of 33250A using drivers again?

Thanks in advance.

AC Function generator: 33250A Agilent

If you are using an Agilent GPIB controller with LabVIEW you need to enable Passport in NI-VISA. I am assuming, of course, that you are using NI-VISA as your primary VISA.

Can I Use Both National Instruments (GPIB) and Agilent/HP (HPIB) Controllers in the Same System?

I found the error related to the problem. After the connection is set up, i try to initialize the function gen using driver supported from NI certified drivers and i could not see the port. 

I run MAX and from Configuration menu, i just pressed "Devices and Interfaces" section. After then, I run VI and it worked. But, when i restart the computer, i realized that inialize.VI did not work again. I did the same from MAX and it worked again. I suppose, there is a easy solution. How can i permanently see the ports without using this MAX "Devices and Interfaces" click? Thank you.

Hi sgorumlu,

Which particular initialize.vi function are you using, and how are you specifying the device to initialize?  Are you getting a particular error message when you run your VI before opening MAX and clicking on "Devices and Interfaces"? It may be that you can utilize the "refresh" option in a ring control to do the same thing.
