"Include Zeroing"
Performs a zeroing procedure before acquiring the user correction
data to improve precision. Since during zeroing no signal may be
applied to the sensor, RF is temporarily switched off at the generator.
When unchecked, the zeroing procedure is skipped. The RF signal
level might be blanked shortly. This setting is recommended if blank-
ing of RF is undesirable or the absence of power at the sensor can
not be guaranteed.
"Execute"
Performs automatic filling of the list, provided a sensor is detected
and the user correction list contains at least one frequency value.

"Amplitude"
Shows the currently set level.

5.3.5.7 Reverse Power Protection
The reverse power protection prevents against overload by an external signal applied
to the RF output of the R&S SMC.
The reverse power protection is tripped when the power of the external signal becomes
too high. A relay opens and interrupts the internal connection to the RF output. This
condition is indicated in the display header by the "OVERLOAD" status message.
Overload
If an "Overload" status message is indicated in the display header, reset the overload
protection by pressing the RF ON/OFF key.
The RF input is activated when the overload protection is reset.
