DISPlay[:WINDow<1|2>]:TRACe<1 to 3>:Y[:SCALe]:RLEVel:OFFSet
-
200dB to 200dB
This command defines the offset of the reference level in the selected measurement window.
Depending on the coupling of the measurement windows, it is valid for both screens (
INSTrument
:COUPle ALL
) or only for the selected measurement window (
INSTrument:COUPle NONE
).
The numeric suffix at TRACe<1 to 3> is irrelevant.
Example: "
DISP:TRAC:Y:RLEV:OFFS -10dB"
Characteristics: *RST value: 0dB
SCPI: conforming
DISPlay[:WINDow<1|2>]:TRACe<1 to 3>:Y[:SCALe]:RPOSition 0 to 100PCT
This command defines the position of the reference value in the selected measurement window. The
numeric suffix in TRACe<1 to 3> is irrelevant.
With the FM demodulator (FS-K7) switched on, the reference position for result display RF POWER
and SPECTRUM is kept separate from that for result display FM.
In operating mode NETWORK (Ext. Generator Option FSP-B10) with active normalization,
RPOSition defines the reference point for the output of the normalized measurement results.
Example:
"DISP:TRAC:Y:RPOS 50PCT"
Characteristics: *RST value: 100PCT(SPECTRUM mode)
50 PCT (NETWORK and FM DEMOD mode)
50 PCT (Mode FM-DEMOD with FM display)
100 PCT (Mode FM-DEMOD with AF spectrum display of FM)
SCPI: conforming
DISPlay[:WINDow<1|2>]:TRACE<1 to 3>:Y[:SCALe]:RVALue <numeric_value>
If the external generator control option (FSP-B10) is mounted and the normalization in the
NETWORK mode is activated, this value defines the power value assigned to the reference position
in the selected measurement window. This value corresponds to the parameter REFERENCE
VALUE in manual operation.
The numeric suffix at TRACe<1 to 3> is irrelevant.
Example: "
DISP:TRAC:Y:RVAL -20dBm"
(spectrum analysis)
"
DISP:TRAC:Y:RVAL 0"
Sets the power value assigned to the reference
position to 0 dB (Tracking Generator /Ext. Generator
Control option) or 0 Hz (FM demodulator option).
Characteristics: *RST value: 0 dB (Mode NETWORK)
0 Hz (FM demodulator mode with FM display)
2.5MHz (FM demodulator mode with AF spectrum display of FM)
- coupled to reference level
0 dB
