Waveform Display

[Dennis_Knutson]

No, the driver is for 546xx model scopes. It does not require any digital channels.

Saying 'a bunch of error messages' is not at all descriptive. Surely you can do a bit better than that. Explain what example you are running and the specific errors.

The error box on the VI front panel has this information: BFFF0015 and the box below it has: VISA Read in ag546xx Fetch Digital Waveform Both.vi->ag546xx Read Digital Waveform.vi->ag546xx Acq Digital Wfm Edge Triggered.vi.  Then it is showing 16 errors like this: "The VI expected to be at "<instrlib>:\ag546xx\ag546xx.llb\ag546xx Read Digital Waveform.vi" was loaded from "C:\Program Files\National Instruments\LabVIEW 2011\instr.lib\ag546xx\ag546xx\ag546xx.llb\ag546xx Read Digital Waveform.vi".  Maybe I am installing/unzipping the VI in the wrong place or the wrong way?

"BFFF0015 and the box below it has: VISA Read in ag546xx Fetch Digital Waveform Both.vi->ag546xx Read Digital Waveform.vi->ag546xx Acq Digital Wfm Edge Triggered.vi. "

This error is a timeout error.  The VISA system did not get a reply when it asked for it.  I suspect this is because you are trying to read a digital waveform when you scope does not support that function.  There should be a simple Fetch Waveform.VI that you can use to read out the displayed waveform.  If you cannot find it, let us know.  I can post a screen shot of where you should be able to find it once I get back to my desk.

"Then it is showing 16 errors like this: "The VI expected to be at "<instrlib>:\ag546xx\ag546xx.llb\ag546xx Read Digital Waveform.vi" was loaded from "C:\Program Files\National Instruments\LabVIEW 2011\instr.lib\ag546xx\ag546xx\ag546xx.llb\ag546xx Read Digital Waveform.vi"". 

These are not errors, but information telling you that the VI file structure has been modified from it's last save.  This is nothing to worry about right at the moment.

You obviously understand that your model of scope has no digital channels yet you ran a digital channel acquisition. That makes no sense. You also obviously ignored my advice about the automatic download and installation and decided to do it all on your own. Both the error and warnings are your mistakes.

 I would appreciate it if you could tell me where I can get the Fetch Waveform.VI.  What we really need is a scope with GPIB or ethernet but I am stuck with the serial port interface so I will make the best of it.  Thanks so much for the help so far.

It's on the Data>Low Level Acquisition palette.

Troy it would be nice if you would send me a screenshot of the location of the VI.  I cannot find the Data>Low Level Acquisition palette in my 2011 trial version of Labview.  Is it in the controls or functions palette?  Is it on the NI website? I searched the drivers on the NI site and no luck there.

Here you go.

I attached a screen shot of labview.  It looks to me like Labview cannot read the files properly.  Maybe I need to reinstall?  Do I just let it install the driver automatically?  That is what I did last time.

Brian,

When you installed the driver, did you just un-zip it into the instr.lib folder?  If you did, it should have created a new folder called Agilent 546XX Series.  After doing that, you would have to restart LabVIEW and then the pallet should show up correctly.  I have included a screen shot of how my instr.lib folder looks. 

Also, when you installed LabVIEW did you also install the instrument drivers DVD?  This install is important for VISA and other functionality that is needed for doing instrument communication and control.
