The
REFERENCE FIXED
softkey defines the level and the fre-
quency or time of
MARKER 1
as a reference for one or several
delta markers. The measured values for one or several
markers displayed in the marker info field are derived from this ref-
erence point instead of the current values of the reference marker
(
MARKER
1).
On actuating the softkey, reference fixed is switched on and thus,
the level value and the frequency, time or x-level value of
MARKER
1
immediately become the reference point.
Additionally, the
REFERENCE
FIXED
softkey opens the submenu
where it is possible to determine manually a reference point with
level and frequency, time or x-axis level, to define a level offset or
deactivate the reference point.
The
REFERENCE FIXED
function is useful for the measurement of
the harmonic suppression at small span (fundamental not repre-
sented).
REF FIXED
ON OFF
The
REF FXD ON/OFF
softkey switches on or off the relative
measurement to a fixed reference value (
REFERENCE POINT
)
independent of the trace.
IEC/IEEE-bus command:
CALC:DELT2:FUNC:FIX ON
REF POINT
LEVEL
The
REF POINT
LEVEL
softkey enters a reference level independ-
ent of the reference marker level. All relative level values of the
delta markers refer to this reference level.
IEC/IEEE-bus command:
CALC:DELT2:FUNC:FIX:RPO:Y -10dBm
REF POINT
LVL OFFSET
The
REF POINT LVL OFFSET
softkey specifies a level offset rele-
vant to the reference level. The relative level values of the delta
markers refer to the reference point level plus the level offset.
The level offset is set to 0 dB on enabling the
REFERENCE FIXED
or
PHASE NOISE
function.
IEC/IEEE-bus command:
CALC:DELT2:FUNC:FIX:RPO:Y:OFFS 0dB
REF POINT
FREQUENCY
With the
REF POINT FREQUENCY
softkey a reference frequency
can be manually activated for the delta markers when the
REFERENCE FIXED
or
PHASE NOISE
function is used.
IEC/IEEE-bus command:
CALC:DELT2:FUNC:FIX:RPO:X 10.7MHz
