Forward/Reflected Power
The
Forward/Reflected Power
page (see Figure 2.86 ) allows the forward/reflected power to be
calibrated based on the filter lag, the ideal PA impedance (magnitude and phase), the test load
impedance and the measured RF current. Nautel sets these values at the factory. Value changes are
not typically required unless you are performing a frequency change.

Attempting to turn off ( Disable) the SWR Protection will display the following WARNING, prompting

WARNING: Factory settings are established at the factory and should not require any adjustment.
These settings affect critical system protections. Making changes to these settings may void your
warranty. Contact Nautel before making changes.
For future reference, record a parameter value before and after making a change.
