Calibrating the Signal Processor from the Command Line

  1. In the terminal window, type: zauto -cal

    The utility displays a series of messages indicating the siggen (signal generator) values and DSP values used in the calibration, such as the following:

  2. If the new values deviate too far from the reference information, the file is not saved. To accept the new values:
    1. Run Zauto.
    2. In the AutoCal Config menu, change the tolerance fields.
    3. Rerun the utility
