Hi I am using a MSO 2014 oscilloscope with the tdkpo2k driver to interface labview. The program is built (.exe file) and samples one of the channels and displays the signal in real time in labview. The oscilloscope is connected to the computer via usb and it works quite good most of the time.
However, the program freezes randomly, sometimes after 20 sec, sometimes after 20 min. Sometimes it starts working again without me having to do anything, and sometimes it wont work until I have restarted the program several times.
I thought this problem was caused by play in the usb ports so I installed the program on another computer, but that didn't help. Does anyone know what
could cause this?
Thanks,
Rui

I'm using the same scope and driver for hours on end. Are you using an external USB hub? Make sure it can supply the required voltage and current. Also make sure the OS is not turning it off in an 'energy saving' manner.
p.s. Please post new questions to the instrument control board. This board is for NI digitizers.
