Selecting a measurement function
The R&S NRP can combine measured values from several channels (sensors) using a mathematical
function and display the result in the selected window. The necessary settings are made in the
Func-
tion...
dialog box.
The first step is to select the measurement function, i.e. the mode of combination for multi-channel
measurements. Possible functions are the power ratio of two channels, a matching measurement func-
tion derived from this or the power in a single measurement channel. All or any of the connected sen-
sors can be selected. A primary channel, and possibly a secondary channel, can be selected for each
measurement window.
The simplest case is a measurement with just one sensor. To configure this measurement, first of all
select
Primary (X)
or
Secondary (X)
(
X
=
A
,
B
,
C
or
D) i
n the
Function
list and then the channel (sensor)
you want in the
Primary Channel
or
Secondary Channel
list. Select the function
Ratio (X/Y)
to measure the
power ratio and then the measurement channel assignment. For all dual-channel measurements, the
first argument “X” of the measurement function is the primary measurement channel. For the sake of
clarity, the primary measurement channel is referred to as the
Incident Power
for matching measure-
ment functions (SWR, Rcoeff and Rloss) and indicates the forward wave, i.e. the wave that is incident
at the DUT.
