Addressing measurements and power sensors
<Measurement> suffix
The R&S NRX memorizes sensor assignments. Thus, a sensor type that has been
connected before is assigned to the same measurement type when it is connected
again. See also
Chapter 5, "Measurement basics"
The sensor assignment is deleted by a preset, reset or sanitization. If the R&S NRX
has no memory of a previous sensor assignment, the R&S NRX assigns the measure-
ments according to the port, to which the power sensors are connected. The number of
measurement panes is adapted automatically.
Example:
For configuring measurements, the
CALCulate<Measurement>
commands are
used.
The first power sensor is connected to port
A. It is assigned to the first measurement,
addressed by
CALC1
.
The second power sensor is connected to port
C. It is assigned to the third measure-
ment, addressed by
CALC3
.
The third power sensor is connected to port
B. It is assigned to the second measure-
ment, addressed by
CALC2
.
All three power sensors are the primary sensor in the assigned measurement.
[:CHANnel<Channel>] suffix
If there is only one power sensor assigned to a measurement, you can omit
[:CHANnel<Channel>]
. Otherwise, the primary sensor is always addressed by
CHAN1
, and the secondary sensor is always addressed by
CHAN2
.
If you use calculation functions that process the results of two power sensors, you
assign a primary sensor and a secondary sensor. In
, the position of the power sensor in the expression defines the
power sensor as primary or secondary sensor.
