The frequency sweep settings are transferred to the sensor to automatically calcu-
late the correct measurement value for each frequency point.
●
Power versus power (power sweep, AM/AM)
Power sweep measurements are executed using the frequency settings of the gen-
erator. Alternatively, the sensor can be adjusted to a frequency different from the
generator, see Use Separate Frequency- Power Analysis.
This frequency is transmitted to the sensor to automatically calculate the correct
measurement value.
●
Power versus time (power measurement in the time domain, e.g. R&S NRP-Z8x
trace mode).
In the time mode, you can analyze the signal of the generator but also externally
supplied signals. This mode requires an additional trigger event, with selectable
level, hysteresis and drop time. Provided the sensor used supports the power mea-
surement of pulse signals, you can also analyze pulse data in time domain.
Characteristics of pulse data
For R&S NRP-Z8x power sensors that support time domain analysis and automatic
pulse analysis.
The power sensors enable pulse data analysis in measurement mode time. All impor-
tant pulse parameters are measured after setting the threshold levels. The following
graph shows most of these parameters:
The sensor calculates the pulse parameters from each measurement and delivers the
results to the R&S SMA100B.
The indication state of the parameters also affects the save function. Storing the mea-
surement diagram as hardcopy includes the parameters selected in this dialog.
