3.5 Calibration
The R&S
ZVA-Z90 and the latest variant of the R&S
ZVA-Z110 (order number

) allow for a variation of the output power by changing the input power.
With these converter types the "R&S ZVA Frequency Converter Leveling Tool" can be
applied for the linearization of output power in the frequency range of interest. See
documentation "Software Utility R&S ZVA frequency converter leveling tool. Getting
Started" for further details.
With other converter models, the output power can only be manually set using the
adjusting screw. This does not allow for a power flatness calibration. A power calibra-
