Ref Point Frequency (span > 0)/Ref Point Time (zero span) ← Ref Fixed
Opens an edit dialog box to enter a frequency reference or time value. All relative fre-
quency or time values of the delta markers refer to this frequency reference. For phase
noise measurement, input of reference time is not possible.
Remote command:
CALCulate<n>:DELTamarker<m>:FUNCtion:FIXed:RPOint:X
Peak Search ← Ref Fixed
Sets the maximum value of the selected trace as the reference point.
Remote command:
CALCulate<n>:DELTamarker<m>:FUNCtion:FIXed:RPOint:MAXimum[:PEAK]

n dB down
Opens an edit dialog box to enter a value to define the level spacing of the two tempo-
rary markers to the right and left of marker 1 (default setting: 3 dB). Activates the tem-
porary markers T1 and T2. The values of the temporary markers (T1, T2) and the
entered value (ndB) are displayed in the marker field.
If a positive value is entered, the markers T1 and T2 are placed below the active refer-
ence marker. If a negative value (e.g. for notch filter measurements) is entered, the
markers T1 and T2 are placed above the active reference marker. Marker T1 is placed
to the left and marker T2 to the right of the reference marker.
In the marker table, the following results are displayed:
Span setting
span > 0
span = 0
If it is not possible to form the frequency spacing for the n dB value (e.g. because of
noise display), dashes instead of a measured value are displayed.
