PM display:
The softkey is not available if logarithmic display is set ( "Deviation Lin/Log" softkey).
Remote command:
DISPlay[:WINDow<n>]:TRACe<t>:Y[:SCALe]:PDIVision
Reference Position ← AF Range
Determines the position of the reference line for the modulation depth or the phase
deviation (Analog Demodulation only) or frequency deviation on the y-axis of the dia-
gram. By default, this line is set to 0.
The position is entered as a percentage of the diagram height with 100 % correspond-
ing to the upper diagram border. The default setting is 50 % (diagram center) for the
display of the AM, FM, or PM signal, and 100 % (upper diagram border) for the AF
spectrum display of the AM, FM, or PM signal.
Remote command:
DISPlay[:WINDow<n>]:TRACe<t>:Y[:SCALe]:RPOSition
Reference Value ← AF Range
Determines the modulation depth or the phase deviation (Analog Demodulation only)
or the frequency deviation at the reference line of the y-axis. The reference value is set
separately for each display of the AM, FM, and PM signal and the AF spectrum of the
AM, FM, and PM signal.
●
AM/FM/PM signal display
The trace display takes individual frequency/phase offsets into account (in contrast,
the
quency/phase offset of the signal, and can therefore not be activated simultane-
ously).
Possible values: 0 and ± 10000 % (AM), 0 and ± 10 MHz (FM), 0 and ± 10000 rad
(PM).
●
AF spectrum display of the AM/FM/PM signal
In the default setting, the reference value defines the modulation depth or the
FM/PM deviation at the upper diagram border.
Possible values: 0 and 10000 % (AM), 0 and 10 MHz (FM), 0 and 10000 rad (PM).
Remote command:
DISPlay[:WINDow<n>]:TRACe<t>:Y[:SCALe]:RVALue
AF Coupling AC/DC ← AF Range
Controls the automatic correction of the frequency offset and phase offset of the input
signal:
(Note: This function is not available with the AF spectrum display of the FM or PM sig-
nal.)
