I am writing a LabVIEW program to collect a time and period measurement from a 53131A. After I read the measurement the counter displays "HP IB -221 ". A measurement is collected no error dialog is thrown until I go to the exit state where I close the connection.
I've looked over the different settings and everything seems to be configured.
The 221 error in the manual states:
221 Settings conflict: Indicates that a legal program data element was parsed but could not be executed because due to the current counter state.
If anyone else has had this issue, please let me know.
