Example:
Assume the following measurement parameters:
●
Start frequency: 1.000 GHz
●
Stop frequency: 6.000 GHz
●
=> Span: 5 GHz
●
sweep points: 1000
●
=>bin: 5 MHz (span/<sweep points>)
The first trace point is displayed at (<f
start
> + bin/2) = 1.0025 GHz.
The last trace point is displayed at (<f
stop
> - bin/2) = 5.9975 GHz.
A marker placed at 1.000 GHz indicates the same result as a marker placed at 1.0025
GHz, since no other value is available.
For trace values in the frequency domain, you can select which method is used to
determine the x-values in the frequency domain, that is:

Note the possible minor discrepancy between marker values and trace values using
the start/stop method.
Analyzing several traces - trace mode
If several sweep are performed one after the other, or continuous sweep are per-
formed, the trace mode determines how the data for subsequent traces is processed.
After each sweep, the trace mode determines whether:
●
The data is frozen (View)
●
The data is hidden (Blank)
●
The data is replaced by new values (Clear Write)
●
The data is replaced selectively (Max Hold, Min Hold, Average)
Each time the trace mode is changed, the selected trace memory is cleared.
The trace mode also determines the detector type if the detector is set automatically,
see
"Mapping samples to sweep points with the trace detector"
The R&S
FSV/A supports the following trace modes:
Table 7-4: Overview of available trace modes
Trace Mode
Description
Blank
Hides the selected trace.
Clear Write
Overwrite mode: the trace is overwritten by each sweep. This is the default setting.
All available detectors can be selected.
