The change of this value changes both the reference level readout and the amplitude readout
of the marker; but does not impact the position of traces on the screen.

2.1.3.8 Correction
Correct the displayed amplitude to compensate for gains or losses from external devices such
as antennas and cables. When using this function, you can view the correction data table and
save or load the current correction data. When amplitude correction is enabled, both the trace
and related measurement results will be mathematically corrected. Positive correction values
are added to the measured values. Negative (-) correction values are subtracted from the
measured values.
1. RF Input
Set the input impedance for numeric voltage-to-power conversions. To measure a 75 Ω device,
you should use a 75 Ω to 50 Ω adapters to connect the analyzer with the system-under-test
and then set the input impedance to 75 Ω.
2. Apply Correction
Enable or disable amplitude corrections. Default is Off. The analyzer provides four correction
factors that can be created and edited separately, but they can be applied independently in any
combination.
