Why does Tektronix scope keep resetting?

I have a new TDS420A Tektonix oscilloscope here and I am trying to display
a continuous wave from it to the PC. I have d/l all the drivers from the
NI site and have made a program that will display a waveform. The problem
arises when I try to display the waveform in a more "real time" mode. I
am dealing with low frequency waves and they "scroll" across the display
on the TDS420A, but when I try to view them this way using my VI, it keeps
resetting itself. I have already wired a constant False expression to the
reset connection on the Intialize.vi driver so that is not the problem.
Any ideas/suggestions would be greatly appreciated. Thanks!

Darrell,

The one other thing I can think of that could be causing the reset is if
you are calling the "TKTDS Setups.vi". This is called in the Getting Started
example that is included with the driver. If the "Operation" parameter is
set to "Autosetup" that has the effect of resetting the instrument to the
factory default settings. Hope this helps. One thing you could do is place
breakpoints after each VI in your application and see which VI is causing
the "reset" to occur, you could then try and see if any of the inputs in
that VI could be causing the "reset".

Good luck,
Kamran
