Ampl Ref Off On
Supported All
This softkey toggles the operating state of the amplitude reference mode. When
amplitude reference mode is turned on, the amplitude value displayed is equal to the
current hardware output power minus the reference value set by the
Ampl Ref Set
softkey. All subsequent amplitude parameters are then relative to the reference value.
Amplitude offsets can be used with amplitude reference mode. In this situation, the
display will show the amplitude calculated as the current hardware output power minus
the reference value plus the amplitude offset.

Remarks Amplitude reference mode changes the display only, it does not change
the RF output power.
Ampl Ref Set
Supported All
This softkey enables you to set the current output power as an amplitude reference
value. It also causes the
Ampl Ref Off On key to toggle to the On position, turning on
amplitude reference mode. All subsequent output power settings are then relative to the
reference value.

Remarks This key sets the reference value equal to the current output power. If
you have not yet set the reference value, the normal preset value for
amplitude reference is 0.0 dBm.
