R&S FSH Spectrum Analyzer Mode
Configuring Spectrum Measurements
Operating Manual 1173.6275.12 - 30 110
- Prefer FFT
The R&S FSH samples the signal levels over time on a defined frequency
value and transforms it to the spectrum by fast Fourier transformation (FFT).
Note that an FFT sweep is not possible under the following circumstances:
● For measurements in the time domain (zero span).
● For TDMA Power, Spectrum Emission Mask and Spurious Emission
measurements.
● For measurements with a gated trigger.
● If the frequency span is smaller than the resolution bandwidth (RBW).
● If the the resolution bandwidth (RBW) is greater than 300 kHz.
