2.4 Advanced Measurements
(DSA1030/DSA1030-TG Option)
2.4.1 Meas
This key provides plenty of 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), TOI (Third
Order Intermodulation) and Pass/Fail. The measure mode can be Single or Continue
and you can control the measurement through options including Restart, Pause, or
Resume at will.
2.4.1.1 Meas Fctn
After you select a measurement function, the screen is divided into two windows, the
upper window is the basic measurement displaying with a sweep trace, and the lower
window holds the results. Through the Screen Control key you can switch between
different windows and zoom the window.
1. T-Power
Enables the Zero Span mode and starts calculating the power within time domain.
The measureable power types are Peak, Average, and RMS.
Select the T-Power measurement and press Meas Setup to set corresponding
parameters.
2. ACP
Measures the powers of the main channel and adjacent channels as well as the
power difference between the main and each of the adjacent channels. When
enabled, values of both the span and resolution bandwidth of the analyzer are
adjusted to be smaller automatically.
Select the ACP measurement and press Meas Setup to set corresponding
parameters.
3. Channel Power
Measures the power and power density within a specified channel bandwidth.
