PEAKS The PEAKS SUBRANGES softkey defines the search method with which maxima
SUBRANGES are searched for within a scan.
PEAKS
SUBRANGES
Remote command:
MARGIN The MARGIN softkey activates the entry field of the margin, i.e. of an additional
acceptance threshold for the determination of the peak list. The limit line currently
used is shifted by this amount for defining the maxima. The range of values is -200
dB to 200 dB.
Remote command:
FINAL The FINAL MEAS TIME softkey activates the entry field of the time of final measure-
MEAS TIME ment.
Remote command:
AUTOMATIC The AUTOMATIC FINAL softkey selects the automatic routine for the final measure-
FINAL ment. This routine is run according to the available frequency list without user inter-
action.
Remote command:
INTER The INTERACTIVE softkey selects the following sequence for the final measure-
ACTIVE ment:
• A frequency from the frequency list is set together with the associated settings
from the corresponding partial scan.
• The marker is set on this frequency in the scan diagram.
• The final measurement sequence switches to the Interrupted status.
• The signal can be exactly analyzed by modifying the receiver settings.
• CONTINUE AT HOLD starts the actual final measurement, the receiver settings
being restored except the frequency.
• The current frequency replaces the original one in the frequency list (drifting
interference sources)
• Next frequency of frequency list.....
With the AUTOMATIC FINAL softkey in the CONTINUE FINAL MEAS submenu a
switchover can be made to the automatic mode before the measurement is
started anew.

Operating Manual 1302.6163.12 - 03
Determination of a specific number of peak values relative to the
limit lines with the level values being independent of their fre-
quency spectral distribution.
Generating subrange maxima, i.e. the interference spectrum is
further analyzed at frequencies with the highest interference level
of a frequency subrange.
