MDO3024 Teststand IVI read command generate timeout

Post by dlock4 » September 6th, 2016, 11:30 am

I have MDO3024 controlled by teststand 2014 and IVI driver(Ni-max). I using the latest IVI driver tkdpo2k3k4k IVI Driver 1.4.0.

I could acquire waveform from the oscilloscope using IVI command INITIATE and FETCH, but the IVI command READ generate a timeout (see -).

Why the read command generate a Timeout?

What I missing?

Hi dlock,

I can't tell from your trace what communications interface you are using with your scope, but I am going to guess it is Ethernet. This issue usually occurs because the firewall on your PC is blocking the Service Request message from the LXI protocol. To correct it you need to add an inbound exception to your firewall for the executable that is using the IVI driver, or switch your interface to USB.

I have an FAQ about this on our site at the following URL.
