FFT Dynamic Range
Spurious free dynamic range
(Includes spurs, harmonic distortion,
intermodulation distortion, alias products)
Excludes alias responses at extremes of span.
Source impedance = 50 Ω
<−80 dBfs (90 dB typical)
FFT noise floor (typical)
Flat top window, 64 RMS averages
Harmonic distortion
Single tone (in band), ≤0 dBfs
<−80 dBfs
Post-filter harmonic distortion (alias
responses) of a single tone ≤102.4 kHz, ≤0
dBfs
<−80 dBfs
Intermodulation distortion
Two tones (in-band), each ≤−6.02 dBfs
<−80 dBfs
Spurious and residual responses
Source impedance = 50 Ω

Frequency alias responses
Single tone (out of displayed range),
≤0 dBfs, ≤1 MHz (≤200 kHz with ICP on)
2.5% to 97.5% of the frequency span
Lower and upper 2.5% of frequency span
<−80 dBfs
<−65 dBfs
