– 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.

The following mixer signal diagram corresponds to a power sweep:
– RF signal (left side): Analyzer port number (e.g. Port 1), power sweep range or
fixed power, CW frequency, frequency conversion settings (1 / 1 denotes no
conversion).
– LO signals (1 or 2, from below): Signal source (analyzer port or external gener-
ator), fixed power or power sweep range, CW frequency, frequency conversion
settings.
– IF signal (right side): Analyzer port number (e.g. Port 2), fixed frequency = (RF
+ LO) or |RF – LO|, expected power range.
