R&S <strong>FSQ</strong> Instrument Functions<br />

<strong>Analyzer</strong> Mode<br />

As soon as the FFT filters are active (RBW ≤ 30 kHz) the sweep time display field<br />

(SWT) is replaced by the acquisition time (AQT) display field.<br />

FFT is a block transformation so the result depends on the time relation between<br />

the data set to be transformed and the burst or pulsed signal. A gated sweep measurement<br />

for TDMA signals is therefore not provided if FFT filters are used.<br />

Channel Filter<br />

Additionally, a number of especially steep-edged channel filters are available for<br />

power measurements.<br />

The indicated filter bandwidth describes the 3 dB bandwidth.<br />

When you select a channel 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 />
