To improve the accuracy of P
RF-In
, it is recommended to perform complementary
source flatness calibrations at the related analyzer ports (including the cables con-
necting the analyzer port to the RF Input of the frequency converter).
2. Reference receiver calibration
During this step, connect a power meter to the test port of the respective frequency
converter. The calibration consists of a single frequency sweep f
1
, ..., f
n
during
which P
RF-Out
(f
j
) and P
REF
(f
j
) are recorded, where P
REF
(f
j
) denotes the power mea-
sured by the VNA reference receiver.
