The following settings are listed:

Setting Description Restrictions
Sig. Lvl. Set The expected mean signal level for the input signal. Turbo Mode only
Frequency The frequency of the measured input signal.
Time
Data Symbols Shows the minimum and maximum number of data
symbols that a burst may have if it is to be consid-
ered in results analysis.
Turbo Mode only
Samples
Standard Selected measurement standard
Burst Type The type of burst being analyzed.
Modulation Shows the active setting selected in the "Demod
Settings" dialog box: "Demodulator" or "PSDU Mod-
ulation to Analyze".
Turbo Mode only
Burst x of y (z) In case statistic over bursts is switched on (Overall
Burst Count), x bursts of totally required y (No of
Bursts to Analyze) bursts have been analyzed so
far. The value z gives the number of analyzed
bursts by the last update of the statistic.

Setting Description Restrictions
Ext Att The attenuation (positive values) or gain (negative
values) applied to the signal externally (i.e. before
the RF or IQ connector of the signal analyzer), e.g.:
External Att = 10 dB means that before the RF con-
nector of the R&S FSV a 10 dB attenuator is used
External Att = -20 dB means that before the RF con-
nector of the R&S FSV an amplifier with 20 dB gain
is used
Frequency The frequency of the measured input signal.
Cap Time The spectrum analyzer samples the signal for this
time interval length.
PSDU Length Shows the minimum and maximum number of data
bytes that a burst may have if it is to be considered
in results analysis.
