• NOR tkds5000 LabWindows/CVI IVI driver not work for TDS5104, TDS5054B

  I'm trying to get the driver NI LabWindows/CVI IVI (tkds5000 version 1,212) working for the Tektronix TDS5054B scope.  When I execute the following functions, I have the warning 'Is not a valid value for the parameter or property' of 0xBFFA0010:

  IviScope_InitiateAcquisition

  IviScope_GetAttributeViInt32 for IVISCOPE_ATTR_TRIGGER_SCOPE and IVISCOPE_ATTR_ACQ_TYPE

  IviScope_ActualRecordLength

  This is not an exhaustive list of the functions that do not work, but just that I currently see.  There are several functions that work (see this joint SPY OR file).

  The strange thing is that everything works fine when I have an oscilloscope Tektronix TDS5104 connected (file SPY OR see attachment).  The code also works when I have an oscilloscope connected and selected through MAX TDS3054 driver tkds30xx IVI of NOR.

  Is it possible that the driver of version 1,212 tkds5000 does not support fully the TDS5054B?  I looked through the files tkds5000.c and tkds5000.h, but has not seen any dependencies on the model of the oscilloscope for these functions.  Any ideas?

  Thank you!

  So, then I thought about it.  The tkds5000 driver AND works very well.  The problem is that the Tektronix TDS5054B scope do not "initialize" some of the attributes.  For example, I had a problem reading the value of the attribute of slope of relaxation because an invalid value was returned.  If I set the slope of the trigger, first of all, then read it, it works fine.

  Its strange because most of the attributes is set to the correct value corresponding to what is displayed on the oscilloscope screen and the Panel, but not ALL of them.  In addition, other Tektronix oscilloscopes did not require a writing before reading.

  Anyway, thanks a lot NathanT.  I appreciate your help.  You saved me a bunch of time to have to go back and add in a dedicated driver.
