Using the NI tkds 30xx library, but there is a problem with acquiring waveforms

[eltoro]

When I try to use the Initiate Acquisition function that is part of this library, I get the following error message: "the given session or object reference is invalid." The name of the device (created by the "initialize" function) seems to be correct (when I probe it). It is: "GPIB::1::INSTR 4". Does anyone know how to fix this?

Hi Sean

find attached an example, how I've initialized
TEKTRONIX TDS7054 DPO-scope. It was made for
a special application - should demonstrate,
how the address has to look like......
( at that time as I made it, was no driver available
from Tek / Natinst - thatswhy I have reused one )

regards
