Can the USB 6501 be calibrated manually?


There are no calibration services offered for the USB 6501. Calibration is limited to verification of the onboard oscillator's frequency. To perform this verification, you will need to measure the onboard clock to see if it is within the specifications of operating frequency, steps can be found below.
  1. Set up a digital output task in LabVIEW and route a counter to the PFI line output that you are reading. 
  2. View the counter output frequency read. 
  3. Make sure that the frequency reading is within the specified operating range.
