•
Slope defines a linear factor to modify the port-specific source power as a function of the
stimulus frequency. The value can be set for frequency sweeps only.
Impact of the Slope
The channel power pb is defined by the following sweep settings:
•
For a power sweep, the channel power is equal to the stimulus range.
•
For a frequency or CW sweep, the channel power is equal to the fixed internal source Power .
The slope modifies the channel power pb so that the following port power ps (source power) is
obtained:
ps = pb + <Slope> * f
In the formula above, f denotes the difference between the current source port frequency and the start
of the stimulus frequency range. The Slope parameter is not available unless a frequency sweep is
active.

Receiver
Shows and/or defines the receiver settings for each physical port of the analyzer and each external
power meter. No receiver settings are provided for external generators.
Some receiver settings can be defined independently for the reference channel a (the wave generated
by the internal source and measured at the port) and the measurement channel b (the wave from the
DUT) at each port.
