Tektronix Labview Code Is Not

I need to project a vi interface threw LabView 8.0 to remotely control the oscilloscope.

I went to the National Instruments Homepage and downloaded the instrument driver: nbsp; nbsp; nbsp;It is a Plug and Play (project-style), this project already have the vi that I need to control remotely the oscilloscope threw serial interface.

When I run again thenbsp; Tektronix TDS 3000 Series Auto Setup Waveform Acquire.vi, it shows a new error message: nbsp; Error -1074002421 occurred at an unidentified location Possible reason(s):nbsp;tktds3k GetRawWaveformThe wafeform data returned does not meet the specified format.

Rodrigo, nbsp; In the tktds3k Initialize.vi, did you just set the ID Query input to False with a TF constant, or did you modify the vi.nbsp; The vi may be looking for the IDN string from the scope, but getting waveform data, which is causing the error.

If you have the scope set up to output ASCII data this VI will Error as it is looking for the specific header in the binary format.

The main issue I had with binary format on my scope is for some reason I could not explain the voltagediv value affected the number of sample points the scope returned.

I have absolutly NO IDEA why, so I just modified the GetRawWaveform VI to format the ASCII data.

This driver (in my opinion) is not written well and not complete in some aspects, however, with some minor modifications it will work.

Here is a picture of the FALSE condition I modified, eg not Binary so it has to be ASCII.

Hello AndrewAlford, nbsp; Can you please explain the modification you did, I am new to LabView and I can not follow what is going on inside this False Case.

I have the same settings for both channels, scope shows 15 V as standalone device, on LabView screen 10 Volts nbsp; Any advice help, appreciated.

Your code is not clear at all since you provided a link to an image on your c drive.

That doesnt work unless your pc is a web server.:smileywink: Just click the Browse button next to the attachment field below the message body and attach the image to your post.

Sorry bout that. Attached is an image of case 0 along with the actual VI.

Ive tried attaching the main VI again, along with the Fetch and modified GetRawWaveform routines.

Del GetRawWaveform.vi: PPCT State Machine.vi: State Machine.vi Fetch Waveform.vi: Waveform.vi.
