8. To activate the duty cycle correction, select "DutyCycle" and enter a percentage as
the correction value.
9. If you selected "dB" or "%" as units (relative display), define a reference value:
a) To set the currently measured power as a reference value, press the "Meas ->
Ref" button.
b) Alternatively, enter a value manually in the "Reference Value" field.
c) Optionally, select the "Use Ref Level Offset" option to take the reference level
offset set for the analyzer into account for the measured power.
