Ref Point Level
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: CALC:DELT2:FUNC:FIX:RPO:Y –10dBm
Ref Point Frequency (span > 0) / Ref Point Time (zero span)
Opens an edit dialog box to enter a frequency reference or time value. All relative frequency or
time values of the delta markers refer to this frequency reference. For phase noise
measurement, input of reference time is not possible..
Remote: CALC:DELT2:FUNC:FIX:RPO:X 10.7MHz
Remote: CALC:DELT2:FUNC:FIX:RPO:X 5MS
Peak Search
Sets the maximum value of the selected trace as the reference point.
Remote: CALC:DELT:FUNC:FIX:RPO:MAX
Phase Noise 1 2 3 4
Selects the normal marker or the delta markers, activates the marker and opens an edit dialog
box to enter a value for the marker to be set to.
stands for delta marker 1.
Reference Fixed
Opens a submenu for relative measurement to a fixed reference value.
Reference Fixed On/Off
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, Ref Point Frequency, Ref Point Time and Peak
Search).
Remote: CALC:DELT2:FUNC:FIX ON
Sig Count On/Off
Switches the frequency counter on/off. The frequency is counted at the position of the reference
marker (marker 1). If no marker is activated, marker 1 is switched on and set at the largest
signal.
The sweep stops at the reference marker until the frequency counter has delivered a result. The
result is displayed in the marker field (see "Fig. 4-6: Marker values" on page 4.53), labeled with
[Tx CNT]. For more details see "Frequency measurement with the frequency counter" on page
4.56.
