RF signal (left side): Analyzer port number (e.g. Port 1), frequency sweep
range (or fixed frequency, if the LO signal is swept), CW power, frequency con-
version settings (1 / 1 denotes no conversion).
–
LO signals (1 or 2, from below): Signal source (analyzer port or external gener-
ator), fixed power and frequency (or frequency sweep range, if the RF signal is
at fixed frequency), frequency conversion settings.
–
IF signal (right side): Analyzer port number (e.g. Port 2), frequency range =
(sweep range + LO) or |sweep range – LO|, expected fixed power.
