Additional Features: Frequency range: 20 Hz-40 GHz Spectrum analysis with ultra-wide dynamic range  Refresh rate, quasi-analog 25 sweeps/s Displayed noise floor: –150 dBm (typ.) in 10-Hz bandwidth 3rd-order intercept point: +20 dBm typ. 1 dB compression point of RF input +10 dBm Sweep time: Span = 0 Hz  - 1 µs to 2500 s in 5% steps; Span ≥10 Hz -  5 ms to 16 000 s in steps ≤10% ;Error limit <1% Sampling rate: 50 ns (20 MHz A/D converter) Number of pixels:500 AF demodulation types: AM and FM The Rohde & Schwarz FSEK30 Spectrum Analyzer comes with low phase noise and OCXO, 1 Hz resolution bandwidth and an FFT filter. The FSEK30 is outstanding for its extremely low noise floor without any impairment to the dynamic range at large signal levels. This can be seen, for example, from the 1 dB compression point of +10 dBm, which yields a dynamic range of 109 dB even at a resolution bandwidth of 1 MHz, allowing GSM, DECT and EDGE power ramps to be determined.
