The power tracking function is used to monitor, when in the Output Power
control mode, the output power level and automatically adjust the
attenuation to keep the output power to the requested level.

In order to use the power tracking function, you must define a range of
power levels (see Setting the Drift Tolerance on page 27).

To activate the power tracking function:
From the Instrument function tab, click the Power Tracking button.
