Hi Pitol, Bill,

thank for your help first!

i have tried to set IDN to False in initialize.vi, but it's also same problem.

i checked the original DPT project with the original Power supply Chroma, there is also the same error 1073807343, but nothing is changed for this original DPT project.

But...maybe, i have reset the configuration data in MAX, after this there is those problem. so in this case, there is some drivers need to be configured again except for the driver of Power supply and tektronix Oscilloscope?

BG,

THAT's a bombshell you just dropped on us.  If you were using an alias for this instrument, you won't be able to find it any more.  That will cause exactly the symptoms you are describing.

Hi dear Bill,

sorry for my Bombshell😂, hope to get your understanding, and i have tried to update my VISA 17.0 to 19.5, then the above 1073807343 is solved, and the power supply is under controlled. But....hope you two can have a look the below new error:😂if you have time and if its possible for you.

Error -1074000000 occurred at Tektronix 7000 Series.lvlib:Error Query.vi

Possible reason(s):

Instrument reports:

402,"Operation complete"

2241,"Waveform requested is invalid; Waveform data not available; CURV?"

410,"Query INTERRUPTED"

104,"Data type error; Unrecognized NRf data; :CH2:POS N"

0,"No events to report - queue empty"

Complete call chain:

     Tektronix 7000 Series.lvlib:Error Query.vi

     Tektronix 7000 Series.lvlib:Read (Multiple Waveforms).vi

     Vertical_settings.vi

     MAIN_cRIO.vi

looking forward for your idea!

The error is clear. You are trying to read multiple waveforms (Tektronix 7000 Series.lvlib:Read (Multiple Waveforms).vi) but the device cannot provide all requested data (2241,"Waveform requested is invalid; Waveform data not available; CURV?") due to the (104,"Data type error; Unrecognized NRf data; :CH2:POS N").

Are you sure that the Tektronix 7000 Series.lvlib:Read (Multiple Waveforms).vi is properly called in your code? Does the Tektronix have all necessary waveforms ready when you call that VI?
