LIST
EVALUATION
The LIST EVALUATION softkey activates or deactivates the spurious emission mea-
surement LIST EVALUATION. The peak search evaluation is automatically done
during measurement and the results are displayed in a table in the lower part of the
screen.
Following results are listed:
• frequency range
• frequency of the absolute peak power in this range
• level delta to the limit with margin in dB
• limit check state (by color change and an asterisk at the end of the line if failed)
If LIST EVALUATION is switched on, the functions PEAKS PER RANGE , MARGIN ,
PEAK SEARCH and VIEW PEAK LIST are not available.
Remote command:
CALC1:PEAK:AUTO ON | OFF
IF SHIFT Refer to the IF SHIFT softkey in the setup menu.
STOP MEAS See “STOP MEAS” on page 4.219 .
START MEAS See “START MEAS” on page 4.219 .
PEAK SEARCH The PEAK SEARCH softkey starts the process of determining the list of the sub-
range maximums from the existing sweep results. This procedure can be repeated
as often as desired, e.g. to experiment with the various threshold settings.
It is activated only after a measurement has been performed with START MEAS.
Remote command:
CALC:PEAK
PEAKS PER
RANGE
The PEAKS PER RANGE softkey activates entry of the number of peaks per range
that are stored in the list. The value range extends from 1 to 50. Once the selected
number of peaks has been reached, the peak search is stopped in the current range
and continued in the next range. The default value is 25.
Remote command:
CALC:PEAK:SUBR 1...50
