2.4 Measurement
2.4.1 Meas
Provides optional measurement functions. When activated, the screen will be divided into two
parts, the above part is the measure screen which displays traces. The other part is used to
display measurement results.
2.4.1.1 Channel Power
Measure the power and power density within the specified channel bandwidth. When this
function is enabled, the span and resolution bandwidth are automatically adjusted to smaller
values. Select Channel Power and press Meas Setup to set the corresponding parameters.
2.4.1.2 ACPR
Measures the power of the main channel and adjacent channels as well as the power
difference between the main channel and each of the adjacent channels. When this function is
enabled, the span and resolution bandwidth of the analyzer are adjusted to smaller values
automatically.
Select ACPR and press Meas Setup to set the corresponding parameters.
2.4.1.3 Occupied BW
Integrates the power within the whole span and calculates the bandwidth occupied by this
power according to the specified power ratio. The OBW function also indicates the difference
(namely “Transmit Freq Error”) between the center frequency of the channel under
measurement and the center frequency of the analyzer. Select Occupied BW and press Meas
Setup to set the corresponding parameters.
2.4.1.4 T-Power
The system enters Zero span and calculates the power within the time domain. The types of
powers available include Peak, Average and RMS. Select T-Power and press Meas Setup to
set the corresponding parameters.
2.4.1.5 TOI
Automatic measurement of IP3 (Third order Intercept Point), including the power of
fundamental wave and the Third order in the power, and calculate the adjustable Intercept
Point
