TDS5054 Driver

[RachelREO]

I am using Labview to gather data input into a TDS5054 oscilloscope. I downloaded the proper drivers and am having some issues. Mainly, I get an issue with the Configure Timebase vi. I get an error that says:

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


Possible reason(s):

Instrument reports:
113,"Undefined header; Command not found; :HOR:MODE:SCA "
0,"No events to report - queue empty"



Complete call chain:
     Tektronix 7000 Series.lvlib:Error Query.vi
     Tektronix 7000 Series.lvlib:Configure Timebase.vi
     Tektronix 7000 Series Acquire Multiple Waveform.vi

The weird thing is that I am able to run Error Query.vi with no problems, it is only when it is encoutered as a subvi that there are issues. Does anyone have any idea what could be happening?

Thanks,

Rachel

The error query is not the problem. It is correctly reporting the error that the instrument sees. Check the syntax of that command in the manual. You would not be the first to discover a bug in a driver.

According to the error message, probably the issue is caused by an incorrect command :HOR:MODECA. You could easily locate the command in  Configure Timebase vi . You could also found with Control in the front panel is related to this command. 

You might try the following things.

1. If you don't care the function the command provided, just remove it from the VI

2. If you need the function, please found the correct command for this model in the programming guide. Then replace it with the correct one you find.

Thanks,

Hi Rachel, do you still get error there?

In order to help isolate the issue there are a few things that I'm curious about regarding your system:

1. What OS are you using?

2. What version of LabVIEW are you running?

3. How are you connected to the instrument (GPIB, USB, ethernet)?

The problem seems to be resolved. We looked at the driver package for the DPO 2000 4000 series and changed some of the HOR:MOD commands to HOR:MAI: commands and everything now appears to be running smoothly.

Oh! Glad to hear that!

And thanks a lot for sharing the solution with us.
