Meas Setup
If in a measurement, Meas Setup displays one of six measurement setup
menus. The setup menu displayed depends on which measurement
(Channel Power, Occupied BW, ACP, Multi-Carrier Power, Power Stat CCDF,
Harmonic Distortion, Burst Power, Intermod (TOI), Spurious Emissions, or
Spectrum Emission Mask)
has been selected in the MEASURE menu.
NOTE The measurements described below are those available in SA mode (see
Mode key). Other measurements are available in other modes if an
optional personality is installed.
Channel Power Meas Setup Menu Keys
To access the following keys for setting up a channel power
measurement, press
MEASURE, Channel Power and then the front-panel
Meas Setup key.
Avg Number
On Off
Press Avg Number (On) to specify the number of averages used when
calculating the measurement result. The average will be displayed at
the end of each sweep.
Avg Number (Off) disables measurement
averaging.
Key Access:
Meas Setup
Avg Mode
Exp Repeat
Allows you to select the type of termination control used for the
averaging function. This determines the averaging action after the
specified number of measurements (average count) is reached.
Avg Mode has no effect on measurements that are not averaged.
Exp Each successive data acquisition after the average
count is reached is exponentially weighted and
combined with the existing average. Exponential
averaging weights new data more than old data, which
facilitates tracking of slow-changing signals.
Repeat After reaching the average count, all previous result
data is cleared and the average count is set back to 1.

Meas Setup
Integ BW
Allows you to specify the range of integration used in calculating the
power in the channel, defaults to 2.0 MHz, or is defined by the radio
standard selected. See Table 2-2. The range for this parameter is the
available non-zero span range of the analyzer.
