Meas
Provide various advanced measurement functions, including T-Power, ACP
(Adjacent Channel Power), Chan Pwr (Channel Power), OBW (Occupied
Bandwidth), EBW (Emission Bandwidth), C/N Ratio, Harmo Dist (Harmonic
Distortion) and TOI (Third Order Intermodulation). For advanced measurement
functions, the measurement mode can be single or continuous; you can restart,
pause and resume the measurement.
Measurement Function
This function is an option for DSA700 and is only available when the advanced
measurement kit is installed. When a measurement function is selected, the screen
is divided into two windows with the upper window (the basic measurement
window) displaying the sweep trace and the lower window displaying the
measurement results.
1. T-Power
Ths system enters zero span mode 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. ACP
Measure the powers 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 ACP and press Meas Setup to set the corresponding parameters.
3. Chan Pwr
Measure the power and power density within the specified channel bandwidth.
When this function is enabled, the span and resolution bandwidth are
