frequency information in the dialogs (including the channel list, the marker info fields, and the
marker tables). The same password is used to de-activate the password protection. If no
password is set, Display – Display Config – Frequency Info displays or hides the frequency
information.
 Restart Behavior configures the sweep behavior after a restart (Channel – Sweep – Restart).
Keep Previous Measurement means that the previous measurement results are maintained until
they are replaced by new, valid results. Set all Traces to 0 means that the restart deletes all
previous results and sets the traces to zero. The zeros are progressively replaced by the new,
valid results. The setting is also valid for remote-controlled operation.
If a single sweep is interrupted and restarted while Set all Traces to 0 is active, then the sweep
segment with zero trace data indicates the previous (interrupted) sweep range. A typical scenario
is a sweep in external trigger mode, where the triggered measurement sequence is a sweep
segment or point: The sweep will be interrupted when the analyzer receives no more trigger
pulses.
 Calculation of Bandfilter Center Frequency as selects the definition of the center frequency for the
bandfilter search; see Bandfilter parameters. The center frequency f
Center
is calculated from the
measured Lower Band Edge (LBE) and Upper Band Edge (UBE) values. If Geometric mean is
selected, f
Center
= sqrt (f
LBE
* f
UBE
). On a logarithmic frequency scale, this ensures equal spacing
from the band edges. If Arithmetic mean is selected, f
Center
= (f
LBE
+ f
UBE
)/2.
The arithmetic mean value is always larger than the geometric mean value. Both values are close
if the bandwidth is small compared to the center frequency.
 Process Options offers settings to control aspects of the NWA application
Set Priority of Process Nwa.exe selects the priority of the running NWA application. Normal
priority is the recommended setting for most measurements. Raise the priority for remote-
controlled measurements which produce large amounts of data that the network analyzer must
process synchronously and without interruption. Note that a higher priority of the NWA application
can adversely affect the performance of other processes running on the analyzer.
Error Dump Type controls the amount of diagnostic information collected when the NWA
application encounters an error.
When the firmware encounters an internal error it writes a dump file to disk. Dump files are
included in the System Report and can help to identify issues. They are small and should not
affect normal operation. Generation of dump files can still be disabled altogether by selecting
None from the Error Dump Type list. The remaining options (Normal, Large, Full) should only be
used when instructed to do so by R&S Support.
