stop frequencies. If the scan table defines a frequency range greater than the scan
range, frequencies outside the scan range are not considered in the measurement.
To avoid situations like this, you can align the start and stop frequency of the scan to
the frequency range defined by the scan ranges (see
"Adjusting the frequency axis"
Example:
In the picture below, the frequency range highlighted in red is covered by the scan
table, but not by the overall scan range. Thus, it would not be considered in the scan.
Figure 9-9: Scan range vs subranges of a scan
There may be gaps between the stop frequency of one range and the start frequency
of the next, for example if parts of the spectrum are not necessary to be tested. Gaps
between ranges are not considered in the scan.

Interrupting a Scan
Access
: [RUN SGL] / [RUN CONT] > "Hold Scan"
The R&S
ESW allows you to hold a scan any time with the "Hold Scan" feature. If you
hold it, the scan is interrupted immediately. When held, you can change settings that
have a direct effect on the scan, for example the frequency.
When you are finished changing the configuration, you have several options on how to
proceed.
●
Continue at the receiver frequency
Resumes the scan at the receiver frequency the R&S
ESW is currently tuned to.
This is any frequency that is equal to or smaller than the hold frequency.
If you do not change the frequency, resuming the scan at the receiver frequency is
the same as resuming the scan at the hold frequency.
●
Continue at the hold frequency
Resumes the scan at the frequency it has been interrupted at.
For example, when you interrupt the scan at 20
MHz, the scan would continue at
that frequency.
●
Stop the scan
Aborts the scan altogether.
