Functions and their use
The Function drop-down list itemizes all the measurement functions
provided by the R&S NRP. These are:
Function
Primary (A) Power in the primary channel, e.g. A.
Secondary (B)
Power in the secondary channel, e.g. B.
Ratio (A/B)
Ratio of the power in the primary channel to the power
in the secondary channel.
SWR (A,B)
Standing wave ratio
RCoeff (A,B)
Reflection coefficient
RLoss (A,B)
Return loss

ä↔ä
Diff (A-B)
Power difference between the primary and secondary
channel.
Sum (A+B) Sum of power from first and second channel.
Scope (A) This function cannot be selected from the "Function &
Unit“ dialog box but automatically appears there when
the primary channel is in the
Scope mode. The Scope
mode does not allow relative measurements or
two-channel measurement functions (ratio, SWR, etc).
The functions for the matching measurement are so defined that the
forward power must be measured in the primary channel and the re-
verse power in the secondary channel.

Prim. Channel –
( )
ä↔ä
Selects the primary channel which is to be used to calculate the dis-
played value.
If the selected channel is operating in the
Scope mode, its power is
automatically shown as a function of time ("Scope (X)" function). Ex-
cept for the graphical display, it is the same as the "Primary (X)" func-
tion. It is not possible to select another measurement function.
Sec. Channel –
( )
ä↔ä
Selects the secondary channel which is to be used for the calculation.
