Hi
I am trying (without much luck) to use IVI drivers in Test Stand and an Agilent MSO7104B scope.
I insert an IVI scope step and setup the settings for normal aquisition and width triggering with a level 0.9V.
I don't get an error message but the trigger level does not get set to 0.9V so all my measurements fail.
I can perform the setup using a lab view call and IVI steps in a labview vi, but then when I call an ivi test stand step to initiate the scope I get an error saying that I need to configure the scope first.
Help,
How do I do a simple thing like setup the scope from within test stand?
I am using the agilent IVI driver. I tried the NI IVI driver for that scope but it does not support width triggering.

Hi JacobM123,
I have found a couple of links for you that you may find useful
Please ensure that you have installed the IVI correctly in MAX
http://www.ni.com/white-paper/3377/en
follow the steps out lined in this white paper
Perhaps take a look at this KB

Let me know how you get on

well in NI MAX the driver shows both the IVI-C and IVI-COM interfaces, how do I know which is being used in either Lab View or Test Stand?
I would assume that test stand is using the correct interface.
Note that I do not get an error message from Test Stand

Hi JacobM123
As you are not getting any error message that would lead me to assume that TestStand is using the correct IVI calls.
In TestStand what do you see under IVI?
Kind Regards

Since you are not getting any errors you can also see if the right commands are sent over the communication link to the scope.
In MAX --> Tools there are few tools to monitor the actual command sent to the controlling device.
For example we used to use NI SPY for monitoring SCPI commands for a GPIB controlled Agilent power supply during debug phase.
