Measurement settings
The overall measurement settings used to obtain the current measurement results are displayed below
the title bar (see Fig. 4-45). The following settings are listed:
Setting Description Restrictions
Frequency The frequency of the measured input signal.
Preamble Type The type of preamble of analyzed bursts.
Ref Level The reference level used for the input signal. IEEE 802.11b, g (Single Carrier)
only
Modulation
Shows the active setting selected in the Demod Settings
dialog box: Demodulator or PSDU Modulation to Analyze.
External Att The attenuation (positive values) or gain (negative values)
applied to the signal externally (i.e. before the RF or IQ
connector of the spectrum analyzer), e.g.:
External Att = 10 dB means that before the RF connector of
the R&S FSL a 10 dB attenuator is used
External Att = –20 dB means that before the RF connector of
the R&S FSL a amplifier with 20 dB gain is used
PSDU Data Length Shows the minimum and maximum number of data bytes that
a burst may have if it is to be considered in results analysis.
IEEE 802.11b, g (Single Carrier)

Result summary list
The result summary list shows the overall measurement results and provides limit checking for result
values in accordance with the selected standard. Result values which are within the limit as specified by
the standard are displayed in green. Result values which are outside of the limits specified by the
standard are displayed in red with a '*' to the left. Results which have no limits specified by the standard
are displayed in white. Limit values are displayed in white (not bold) and can be modified, if focused, via
the keypad. To reset the limit values to the values specified in the standard, use the lines menu (LINES
key).
The results displayed in this list are for the entire measurement. If a specific number of bursts have
been requested which requires more than one sweep, the result summary list is updated at the end of
each sweep. The number of bursts measured and the number of bursts requested are displayed to
show the progress through the measurement. The Min / Mean / Max columns show the minimum, mean
or maximum values of the burst results.
