Example:
For calculating the standing wave ratio (SWR), you use
CALC1:MATH:EXPR
"SWR(SENS3,SENS1)"
.
Thus, the power sensor at port C from the example above is assigned as primary sen-
sor, and the power sensor at port A as secondary sensor.
This behavior saves you assigning the power sensors using
CALCulate<Measurement>[:CHANnel<Channel>]:SENSe:INDex
.
Further information:

Assigning measurement panes and traces, see Chapter 13.6, "Measurement set-
tings and results" , on page 196.
13.4 Making measurements
Combining commands, also called high-level commands, simplify programming of the
R&S NRX for measurements. You can configure the parameters that are part of the
parameter list. The other parameters are set to their default values. For details on the
command syntax, see
Chapter 13.4.5, "Structure of combining commands" ,
on page 191.
If you need more precise control of the R&S NRX, you can use the commands that
configure only one setting, here called lower-level commands, or combining commands
that include fewer functions. This way allows you to make specific modifications
between the individual steps and configure parameters that are not part of the parame-
ter list.
Figure 13-1 shows the relationship of the commands.

13.4.1 Using MEASure?
The simplest way to program the R&S NRX for measurements is by using
MEASure?
.
But this method does not offer much flexibility. You can configure the parameters that
are part of the parameter list but nothing else; see also
"<parameter_list>"
on page 191.
