2.4 Measurement

2.4.1 Meas

Provide optional measurement functions. When activated, the screen will be divided into two parts. The
upper part is the measurement screen which displays traces, and the lower 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 (Adjacent Channel Power)
Measure 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 (Occupied Bandwidth)
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 (Time Domain 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 (Third Order Intercept Point)
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.
2.4.1.6 Spectrum Monitor
Display the power of the swept spectrum as an intensity color map commonly referred to as a waterfall
chart. Select Spectrum Monitor and press Meas Setup to set the corresponding parameters.
