Opens an edit dialog box to enter a fixed step size for the center frequency.
Remote command:
[SENSe:]FREQuency:CENTer:STEP on page 665

Frequency Offset
Opens an edit dialog box to enter a frequency offset that shifts the displayed frequency
range by the specified offset.
The softkey indicates the current frequency offset. The allowed values range from
-100 GHz to 100 GHz. The default setting is 0 Hz.
Remote command:
[SENSe:]FREQuency:OFFSet on page 824
Signal Track (span > 0)
Opens a submenu to define the signal tracking characteristics:
●
search bandwidth
●
threshold value
●
trace
The search bandwidth and the threshold value are shown in the diagram by two verti-
cal lines and one horizontal line, which are labeled as "TRK". 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.
The submenu contains the following softkeys:
●
"Track On/Off (span > 0)" on page 348
●
"Track BW (span > 0)" on page 348
●
"Track Threshold (span > 0)" on page 348
●
"Select Trace (span > 0)" on page 348
