Start / Stop Frequency
Defines the start and stop frequency for the scan.
The range for the start frequency is f
min
to (f
max
- 10 Hz).
The range for the stop frequency is (f
min
+ 10 Hz) to f
max
.
f
min
and f
max
are defined in the datasheet.

IF Span Manual
Defines the span for IF spectrum analysis.
The receiver (center) frequency is kept constant. Possible span values are in the range
from 10
kHz to 10 MHz.
Available for IF Analysis (firmware application R&S ESR-K56).
Remote command:
[SENSe:]FREQuency:SPAN
on page 825
Full Span
Restores the span to the full available frequency range.
The full span is specified in the data sheet.
In receiver mode, full span is available for IF Analysis and is limited to 10 MHz.
Remote command:
[SENSe:]FREQuency:SPAN:FULL
on page 825
Last Span
Sets the span to the previous value. With this function e.g. a fast change between
overview measurement and detailed measurement is possible.
Remote command:

Signal Track
Opens a submenu to define and enable the signal tracking:
●
search bandwidth
●
threshold value
●
trace
Signal tracking is available for IF analysis and is defined in the [FREQ] menu. After
each sweep the center frequency is set to the maximum signal found within the
searched bandwidth. If no maximum signal above the set threshold value is found in
the searched bandwidth, the track mechanism stops.
