Have to add a delay in Agilent 3446x labview driver

[nanocyte]

I was seeing a weird bug in the Agilent 3446x driver on the driver page.

Running initialize.vi results in a long wait (~2 minutes) followed by this error:

Error -1073807339 occurred at VISA Read in Agilent 3446X Series.lvlib:Error Query.vi->Agilent 3446X Series.lvlib:Reset.vi->Agilent 3446X Series.lvlib:Initialize.vi

Possible reason(s):

VISA: (Hex 0xBFFF0015) Timeout expired before operation completed.

Then if I run the code again I get this error:

Error -1073807360 occurred at VISA Open in Agilent 3446X Series.lvlib:Initialize.vi->Ivan acquire single.vi

Possible reason(s):

VISA: (Hex 0xBFFF0000) Unknown system error (miscellaneous error).

I narrowed it down to a read call in Error Query.vi. I was able to fix it by inserting a 1 second delay in between.

I thought I'd write this up for anyone encountering this issue in the future.

I'm testing with a keysight 34465A firmware V, Windows 10, and Labview 2017.

Thanks for the info! I'm sure this will help people in the future.

You can also email instrument.drivers@ni.com with this write up to provide direct feedback.

Thank you so much, finally it works 

This bug is still existing...

To echo Salazaar.Slytherin above, giving feedback to instrument.drivers@ni.com directly would be helpful feedback.

This is a sneaky bug in the driver. I was tinkering with the driver for 2 days. Thank you for the solution.

Added the delay in the error query.vi and it works perfectly

Windows 7 64bit with Labview 2017 32bits.

Now I can code!

Delay is needed once after the reset (speed up meas)
