Self-Calibration

Self-calibration adjusts the WTS for variations in the environment using an onboard high-precision calibration tone. Perform a complete self-calibration after first setting up your WTS and letting it warm up for 30 minutes.

Note Warm up begins when the WTS has been powered on and the operating system has completely loaded.

The WTS is calibrated at the factory; however, you should perform a self-calibration in any of the following situations:

  • After first setting up the WTS .
  • When the system is in an environment where the ambient temperature varies or the WTS temperature has drifted more than ±2 °C from the temperature at the last self-calibration.
  • To periodically adjust for small performance drifts that occur with product aging.

NI recommends you perform a full instrument self-calibration by executing the CALibration:RF:FULL command either through the WTS Software UI or sending it as a SCPI command.

Note Self-calibration may take up to 10 minutes to complete.
