6.2.1
Controlling the Measurement Results
The R&S NRX can cope with the wide range of measurement scenarios with the help
of the so-called "termination control". Depending on how fast your measurement
results change, you can define, how the measurement results are output.
Repeating termination control
Outputs a measurement result when the entire measurement has been completed.
This means that the number of measurement cycle repetitions is equal to the set aver-
age count. If the average count is large, the measurement time can be very long.
Useful if you expect slow changes in the results, and you want to avoid outputting
redundant data.
Moving termination control
Outputs intermediate values to facilitate early detection of changes in the measured
quantity. This means that for each partial measurement, a new average value is output
as a measurement result. Thus, the measurement result is a moving average of the
last partial measurements. How many of the partial measurements are averaged is
defined by the average count.
Useful if you want to detect trends in the result during the measurement.
6.3
Triggering
In a basic continuous measurement, the measurement is started immediately after the
initiate command. However, sometimes you want that the measurement starts only if a
specific condition is fulfilled. For example, if a signal level is exceeded, or in certain
time intervals. For these cases, you can define a trigger for the measurement.
6.3.1
Trigger States
The power sensor has trigger states to define the exact start and stop time of a mea-
surement and the sequence of a measurement cycle. The following states are defined:
●
Idle
The power sensor performs no measurement. After powered on, the power sensor
is in the idle state.
●
Waiting for trigger
The power sensor waits for a trigger event that is defined by the trigger source.
When the trigger event occurs, the power sensor enters the measuring state.
