The Analyzer Power measurement can be performed with a WIDE resolution
bandwidth (denoting measurement at the front end with no restriction of the
analyzer frequency and level). The wide-band measurement is most accurate if
the correct center frequency is set.
The Pow. Meter Freq. Sel. measurement can be performed with the root-raised
cosine filter specified in standard TIA/EIA-136.xxx (TDMA filter) or with an 1.4
MHz bandpass filter specified for CDMA measurements (CDMA filter).
Resolution bandwidths for the Power and Spectrum measurements can be set
independently (pp. 4.40, 4.49).

Repetition
Repetition determines the repetition mode. Repetition modes for the applications
Analyzer Power and Power Meter Freq. Sel. can be set independently.
Single Shot Single-shot measurement: the measurement is stopped after one
sweep comprising 4096 samples. A stopped measurement is in-
dicated by the status display HLT in the Power softkey.
Continuous Continuous measurement: The CMU measures continuously
until the measurement is explicitly stopped via the measurement
control softkey in the graphical measurement menu (see
Analyzer Power softkey on p. 4.35). The measurement results
are valid after one sweep; however, the measurement is contin-
ued, and the output is continuously updated. An ongoing meas-
urement is indicated by the status display RUN in the Power
softkey.
Single shot should always be selected if only a single measurement result is re-
quired under fixed conditions. The continuous measurement is suitable for moni-
toring the evolution of a measured quantity in time, for example for adjustments.
Note: In remote mode, the counting measurement (counting mode) is avail-
able as a further repetition mode with a defined number of measure-
ment cycles to be performed, see chapter 6 of this manual.

Statistic Count
Statistic Count defines how many sweeps are combined to form one statistics cy-
cle. Each sweep consists of 4096 samples. This setting is available for the Power
Meter Freq. Sel. application; for Analyzer Power measurements the Statistic Count
is always equal to one.
1 to 1000 sweeps Number of sweeps per statistics cycle
The settings 1 and OFF (press ON/OFF key) are equivalent. A statistics cycle de-
termines the duration of single-shot measurements (see Chapter 3, section General
Settings).
