RRC Filter<br />

Filters with root-raised cosine characteristic (RRC) available for power measurements<br />

The indicated filter bandwidth is the 3 dB bandwidth. For RRC filters, the fixed roll-off<br />

factor (alpha) is also indicated.<br />

When you select an RRC filter, the automatic coupling of RBW to the span is not<br />

available.<br />

The table below shows a list of available channel filter.<br />

The MAIN PLL BANDWIDTH softkey defines the bandwidth of the main PLL of the<br />

synthesizer of the R&S <strong>FSQ</strong> and thus influences the phase noise of the R&S <strong>FSQ</strong>.<br />

Three bandwidth settings are possible (High / Medium / Low); if AUTO is selected,<br />

the bandwidth is set automatically (default).<br />
