Power tab
The "Power" tab defines the power of the RF and the LO signals.
The table in the "Power" tab contains the following columns:
●
"Port" contains the RF and IF ports and one or two LO ports, depending on
whether the "2nd Mixer" is selected.
●
"Type" specifies how the power for each signal is defined. Each of the mixer input
signals RF, LO 1, and LO 2 (if present, for ) can be either at the analyzer's channel
base power ("Base Pwr"; the signal is swept if a power sweep is active; it is at fixed
power (CW) for the other sweep types) or at the "Fixed" power. The same applies
to the IF signal.
●
"Start/CW" defines the output powers at the RF, LO 1 and LO 2 ports. The "Base
Pwr" setting overwrites the power settings in the STIMULUS softtool panels: For
power sweeps, "Base Pwr" is the power sweep range. For the other sweep types, it
is the fixed "Power" value.
The "Fixed" power settings also appear in the"Port Configuration" dialog. The
"Start/CW" power for the IF port sets the IF source power for the reverse sweep.
This setting is only relevant if
is active.
●
"Stop" shows the stop value of the power sweep range (for power sweeps only).
If a segmented frequency sweep with segment-specific powers is active, the "Base
Pwr" is no longer editable but set to the minimum and maximum power of the sweep
segments.
