Measurement Setup
Access the frequency Span for the Power Spectrum graphic and the resolution bandwidth (RBW) for the
measurement, by selecting the Func front-panel key.
The maximum available span is 22 MHz, which can be set directly using the Span menu key or selecting
the Full Span menu key. Selecting Last Span toggles between the two most recent span settings. The
spectrum measurement can be set to Zero Span to obtain a power versus time measurement.
The RBW defaults to an auto setting of 10 kHz, but can also be set manually.

Figure 6-2: Channel Power measurement
Channel power measures power in the frequency domain by integrating the power spectrum of the signal
over a specified bandwidth. The measurement displays a graphic of the power spectrum of the signal and
numeric values for the Channel Power in the specified bandwidth and the average power per hertz across
the specified bandwidth. The Channel Power measurements in the LTE and Spectrum measurement
modes are identical.
