"Stimulus" settings), determine the sweep range of the converted signals (for a fre-
quency sweep, the input and output frequencies at the DUT ports). All measured quan-
tities (S-parameters, wave quantities, ratios etc.) and other trace settings are available.
The following example shows the transmission and reflection coefficients of a band-
pass filter in the frequency range between 75 GHz and 110 GHz, which is covered by
the frequency converter R&S ZVA-Z110E.

Please note that the measurement results may be degraded if the setup is exposed to
an electromagnetic field at the R&S ZVA/ZVT receiver frequency (typically 279 MHz).
For best measurement accuracy, observe the following rules:
●
Enter the correct power coefficients of all frequency converters; see
"Entering Power
●
Perform a source power calibration; see
Using converter output powers outside the calibrated range generally impairs the
measurement accuracy. The effect is enhanced if the power coefficients are not
correct.
●
Perform a system error correction for the power-calibrated test setup using an
appropriate calibration kit.
