verter is mounted upside down, e.g. on a wafer prober. If you turn the knob, a
receiver power calibration remains valid, while a system error calibration has to
be repeated if it refers to more than one port.
To set a flat output power over frequency just by entering a dBm value in the VNA
firmware, the leveling functionality of option R&S
ZNA-K8 can be used. Leveling
records the frequency-dependent relationship between the input power at RF IN
and the output power at the waveguide port. The resulting data set can then be
applied by the VNA firmware. For further details, refer to the R&S
ZNA online
help.
Since version 2.40, the leveling functionality is part of the R&S
ZNA firm-
ware. It is enabled with option R&S
ZNA-K8, and integrated into the stan-
dard power calibration routines.
The output power of the VNA is set to a fixed value optimized for the selected
type of converter.
