Select Marker (No) ← Phase Noise
Opens a submenu to select one of 16 markers and define whether the marker is a nor-
mal or a delta marker (see "Marker 1 / Marker 2 / Marker 3 / … Marker 16,/ Marker
Norm/Delta" on page 280). "(No)" indicates the number of the currently active marker.
See "Marker 1 / Marker 2 / Marker 3 / … Marker 16,/ Marker Norm/Delta" on page 280.
Ref Fixed
Opens a submenu to set all values of a reference point. Instead of using the current
values of the reference marker (marker 1) as reference point for the delta markers,
level and frequency or time are set to fixed values and used as reference point.
Ref. Fixed On/Off ← Ref Fixed
Switches the relative measurement to a fixed reference value on or off. The level and
frequency or time values of marker 1 immediately become the reference point, but can
be altered using the corresponding softkeys ("Ref Point Level" on page 289, "Ref Point
Frequency (span > 0)/Ref Point Time (zero span)" on page 289 and "Peak Search"
on page 289).
When set to ON, all delta markers which previously referenced marker 1 are automati-
cally set to reference the fixed marker.
The reference marker assignment can be changed using the "Marker Wizard" (see
"Marker Wizard" on page 281).
Remote command:
CALCulate<n>:DELTamarker<m>:FUNCtion:FIXed[:STATe] on page 617
Ref Point Level ← Ref Fixed
Opens an edit dialog box to enter a reference level value. All relative level values of the
delta markers refer to this reference level.
Remote command:
CALCulate<n>:DELTamarker<m>:FUNCtion:FIXed:RPOint:Y on page 618
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 on page 618
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]

Marker Demod
The marker demodulation function sends the AM data at the current marker frequency
(in a bandwidth corresponding to the RBW) to the audio output. The "Marker Demod"
softkey opens a submenu to set the demodulation output settings.
